Atlantic Hurricane Outlook – August 20, 2025: A Couple Systems In The Atlantic

Hurricane Erin is holding as a Category 2 storm offshore, producing rip currents and coastal hazards along the East Coast. Meanwhile, the Gulf and Florida remain quiet, though tropical waves in the Atlantic are being monitored.

TLDR Version: Click Here

Current Tropical Systems

  • Hurricane Erin:
    Erin has weakened slightly but remains a Category 2 hurricane as it tracks northeast, well offshore of the U.S. East Coast. The storm continues to generate dangerous swells, rip currents, and pockets of coastal flooding, especially from the Outer Banks northward into the Mid-Atlantic and New England. While direct landfall is not expected, coastal impacts remain significant.

  • Disturbance in the Central Atlantic:
    A tropical wave near 45°W continues to show signs of organization. Environmental conditions feature warm sea surface temperatures but are partially offset by moderate wind shear and Saharan Air Layer (SAL) dust intrusion. Development chances: 30% over 7 days.

  • Far Eastern Atlantic Wave (off Africa):
    A fresh wave near 25°W is emerging with scattered convection. It remains disorganized but will be monitored as it progresses westward. Development chances: low (20% over 7 days).

Gulf of America (Mexico) Outlook

The Gulf remains broadly quiet, with high pressure dominating and keeping conditions mostly stable. While moisture pockets are leading to afternoon thunderstorms, there are no signs of tropical development at this time. Sea surface temperatures are very warm (29–31°C), so the region will continue to be monitored closely heading into late August.

Florida Forecast

Florida remains under the influence of high humidity and afternoon sea-breeze thunderstorms, typical for August. Outer rainbands from Erin are not expected to impact the peninsula. No immediate tropical threats are forecast for the state in the near term.

Atlantic Hurricane Outlook – August 10, 2025: Multiple tropical waves crossing the Atlantic; development chances gaining

Multiple tropical waves are moving across the Atlantic today, but Saharan dust, wind shear, and dry air are keeping development chances low. Warm ocean temperatures could allow for changes later this week.

Atlantic Basin Overview

TLDR Version; Jump Here

As of this morning, no named tropical cyclones are active in the Atlantic. Several tropical waves are traveling westward across the Main Development Region (MDR), but most are struggling with environmental challenges that limit development. Sea surface temperatures are amply warm, so these waves will continue to be monitored as they move toward more favorable conditions later this week.

Key Systems We’re Watching

  • Central Atlantic Tropical Wave (~40°W):
    Moving west at 10–15 knots with scattered convection. Organization remains limited due to dry air and moderate wind shear. Low chance of development over the next 7 days.

  • Eastern Atlantic Tropical Wave (~23°W, off Africa):
    Recently emerged from the continent with convection along its southern flank. Battling Saharan dust and dry air, keeping development chances low in the near term, potentially gaining strength in next 7-days.

  • Monsoon Trough Low (~08N44W):
    Embedded within the monsoon trough, sparking intermittent thunderstorm activity. No immediate signs of organized development.

Atlantic Hurricane Outlook – August 3, 2025: Two Areas Now Under Watch

The Atlantic remains calm with no named storms, but two areas—one off the U.S. coast and another off Africa—are now under watch for potential tropical development. Here's today's scientific hurricane outlook.

*Those who like data, continue reading. Those it prefer the quick version, jump to the TL;DR here.

As early August continues, the Atlantic remains without any active tropical cyclones. However, two areas have emerged as brown disturbance watches, as forecasters monitor subtle signs that could impact the Atlantic if conditions shift.

Atlantic Basin Highlights

  • No active tropical storms in the basin.

  • Two areas are now under National Hurricane Center scrutiny:

    Invest Area AL95: Expected to be a fish storm, it’s a non-tropical low just off the North Carolina coast—producing disorganized thunderstorms. (The orange X on the chart)
    Chance of development: Medium (30%) over the next 2–7 days.
    Movement: Toward the east-northeast at ~10 mph, expected to stay offshore.

    Emerging tropical wave off Africa: Near 30°W, forecast to move westward with scattered convection.
    Chance of development: Low (30%) within 7 days.

GOES-19 - Sector view: North Atlantic - Sandwich - August 3, 2025

GOES-19 - Sector view: Tropical Atlantic - Sandwich - August 3, 2025

Key Environmental Conditions

  • Sea Surface Temperatures (SSTs):
    The Gulf of Mexico and Caribbean Sea remain very warm, with temperatures ranging from 29–31°C (84–88°F). The Main Development Region (MDR) is also running slightly above average. These warm waters provide abundant fuel for tropical development — if other atmospheric factors allow.

  • Wind Shear:
    Moderate to high vertical wind shear persists across the central Atlantic, particularly along the latitude band where Disturbance 2 is located. This disrupts the vertical alignment of developing systems and limits the ability of convection to consolidate around a center.

  • Moisture:
    Mid-level moisture is gradually increasing across the western tropical Atlantic and Caribbean. However, the central Atlantic remains drier overall, especially in areas affected by Saharan dust, limiting deep convection and thunderstorm persistence.

  • Saharan Air Layer (SAL):
    A robust SAL is sweeping across the central and eastern Atlantic, characterized by dry, dusty air and suppressed vertical motion. The SAL also contributes to a stable atmosphere, effectively capping thunderstorm development and working against tropical wave organization.

Dust & SAL data from Windy.com

Implication for Disturbance 2:

While ocean temperatures are favorable, the combined influence of high wind shear, limited moisture, and widespread SAL intrusion is expected to stall or inhibit further development of Disturbance 2 as it continues westward across the tropical Atlantic. Until it reaches a more favorable environment, organization remains unlikely.

Gulf of America (Mexico) & Caribbean Region

  • No disturbances active in the Gulf, and high-pressure conditions support light winds and minimal rain outside normal sea‑breeze showers.

  • Eastern Caribbean: A wave near 68°W is producing localized storms over Hispaniola and Venezuela but remains disorganized.

Outlooking Ahead

Invest Area AL95, while moving away from land, bears watching if it gains tropical characteristics. Meanwhile, the wave off Africa will pass into warmer waters—another early‑August indicator. Meteorological models forecast these systems might strengthen if wind shear declines and dust regresses later this month.

TL;DR – August 3 Hurricane Summary

  • No storms currently in the Atlantic basin.

  • AL95 (off North Carolina): 30% chance of development over the next week. (Fish Storm)

  • African wave near 30°W: 20% chance of development within 7 days.

  • Factors are currently favoring disorganization.

  • SSTs are warm and moisture is increasing—conditions may improve in early August.

  • Immediate risk remains low; now is a good window for storm preparedness.

Atlantic Hurricane Outlook – July 19, 2025: Disturbance in the Deep Tropics Eyes Development

A tropical wave southwest of the Cabo Verde Islands shows a low chance of development as it moves westward. Conditions remain mixed across the Atlantic, but signs of activity are increasing.

The Atlantic Basin remains relatively quiet today, but there’s a new player on the map. A tropical wave in the central tropical Atlantic—labeled Disturbance 1—has a low but notable chance of development over the next week. This marks the first sign of deeper tropical activity emerging from the Main Development Region (MDR) as we move closer to peak hurricane season.

Atlantic Basin Overview: One Area to Watch

As of 8:00 AM EDT Saturday, July 19, 2025, the National Hurricane Center is monitoring:

  • No named tropical cyclones

  • One disturbance in the central Atlantic

  • Tropical development chances:

    • 10% over 48 hours

    • 20% over 7 days

Disturbance 1 is a tropical wave located about 900 miles west-southwest of the Cabo Verde Islands, interacting with a broad area of low pressure. Showers and thunderstorms remain disorganized, but marginally favorable conditions could support slow development as the system moves west to west-northwest around 10 mph.

However, by mid-week, environmental conditions are expected to become less favorable, limiting its window for intensification.

Satellite imagery courtesy of Windy.com

Sea Surface Temperatures: Fuel in Place

Waters remain very warm across much of the Atlantic:

  • Gulf of Mexico: Holding above 86°F (30°C) in many areas

  • Western Caribbean: High SSTs remain steady

  • Main Development Region (MDR): Warm enough to support tropical wave development—an important factor as more systems emerge off Africa

These warm waters are key to supporting systems like Disturbance 1.

Sea Surface Temperature data courtesy of Windy.com

Wind Shear & Moisture: Still Mixed

  • Wind Shear: Moderate in the eastern Atlantic near Disturbance 1 but lower closer to the Caribbean

  • Moisture: Rising across the western Atlantic, but dry air from the Saharan Air Layer (SAL) is still suppressing deeper convection across much of the MDR

While the disturbance has some support for development, these mixed upper-atmospheric conditions could limit growth.

Wind Shear July 19, 2025

Atlantic Hurricane Outlook – July 18, 2025: Tropics Quiet, But Gulf Moisture Persists

The Atlantic remains free of tropical storms today, but rising ocean heat and evolving atmospheric patterns point to potential development in the coming weeks. Stay prepared with Cat5Prep's daily hurricane outlook.

The Atlantic basin remains relatively quiet as we enter the weekend, with no active tropical cyclones or immediate threats on the map. However, lingering moisture from a weak low in the Gulf of Mexico continues to impact parts of the Southeast with enhanced rain chances. Meanwhile, environmental signals are gradually shifting toward favorability as we move closer to the climatological ramp-up in late July.

Daily Hurricane Update July 18, 2025 from the NWC NOAAA

Atlantic Basin: Still Quiet, But Watchful

As of this morning’s update from the National Hurricane Center (NHC):

  • No active tropical cyclones

  • No named systems or advisories

  • No tropical development expected over the next 7 days

The basin remains in a holding pattern—but that may change in the weeks ahead.

Satellite imagery courtesy of Windy.com

Sea Surface Temperatures: Running Hot

Ocean heat content continues to build across key development zones:

  • Gulf of Mexico: Sea surface temperatures (SSTs) remain in the mid-to-upper 80s°F (29–31°C), well above average.

  • Western Caribbean: Waters continue to warm, supporting deep convection.

  • Main Development Region (MDR): SSTs between Africa and the Caribbean are approaching thresholds that historically support long-track hurricanes.

These conditions set the stage for rapid intensification when tropical systems do form.

Sea Surface Temperature data courtesy of Windy.com

Wind Shear and Atmospheric Moisture: Becoming More Conducive

While upper-level wind shear remains moderate in parts of the Caribbean and central Atlantic, it is gradually weakening—especially closer to the Gulf. Atmospheric moisture continues to increase:

  • Mid-level moisture is supporting thunderstorm development

  • Reduced shear and rising instability create a more supportive environment for potential tropical waves

This combination is worth monitoring as we approach the latter half of July.

Saharan Air Layer: A Temporary Shield

Dry air and dust from the Saharan Air Layer (SAL) remain active over the eastern Atlantic:

  • SAL suppresses convection by drying out the lower atmosphere

  • It also enhances wind shear, limiting vertical storm growth

  • This protective layer typically weakens in August

While it currently limits tropical wave development off Africa, its influence is expected to wane soon.

Saharan Air Layer (Dust) data courtesy of Windy.com

Gulf Moisture: Lingering Showers, Low Development Risk

A broad area of low pressure and enhanced moisture remains over the northern Gulf of Mexico:

  • Development chances remain very low

  • The system is disorganized, with no surface circulation

  • Still, heavy rain and localized flooding are possible today along the Gulf Coast, particularly in southern Alabama, the Florida Panhandle, and southeastern Louisiana

This disturbance is more of a rainmaker than a tropical threat but illustrates how even weak lows can impact coastal regions.

  • Identify multiple exit routes in case primary roads are closed

  • Plan ahead for pets, medication, and transportation

Being familiar with your zone before a storm is one of the best preparedness steps you can take.

Looking Ahead: A Quiet Stretch, But a Shift Is Coming

While the tropics are calm for now, the combination of warming waters, weakening wind shear, and deepening atmospheric moisture signals that a transition to a more active pattern is coming.

Expect activity to increase in late July into early August, as the historical ramp-up in hurricane season begins.

Atlantic Hurricane Outlook – July 16, 2025: Gulf Disturbance Lingers, Tropics Stay Quiet

A weak low in the Gulf of Mexico brings rain and storms to Florida, but no tropical development is expected. Cat5Prep’s daily update covers real-time conditions, SSTs, and what to watch next.

The Atlantic hurricane basin remains quiet in terms of named storms, but attention continues to center on a weak low-pressure system lingering over the eastern Gulf of Mexico. Although this system remains disorganized and development chances are low, it’s bringing widespread showers and thunderstorms across parts of Florida, the northeastern Gulf, and coastal Georgia.

While no tropical development is expected over the next 7 days, the broader environment is slowly shifting toward favorability, with rising sea surface temperatures, weakening wind shear, and the gradual retreat of the Saharan Air Layer (SAL).

Atlantic Basin Overview

As of the latest NHC update (2:00 PM EDT):

  • No active tropical cyclones

  • One disturbance in the Gulf of Mexico (Low development chance)

  • No tropical formation expected in the next 7 days

Disturbance in the Gulf of Mexico

A broad area of low pressure continues to meander just west of Florida over the northeastern Gulf of Mexico:

  • Development chances remain low (0% over 48 hours, 10% over 7 days)

  • System remains non-tropical and disorganized

  • Producing periods of heavy rainfall, especially across the Florida Panhandle, southern Georgia, and coastal South Carolina

  • Some gusty winds and isolated flooding may occur, especially in areas with poor drainage

This system is expected to drift inland by late Thursday, reducing any tropical potential.

Sea Surface Temperatures (SSTs)

Ocean temperatures remain exceptionally warm, providing high potential energy for storm development once other conditions align:

  • Gulf of Mexico: 86–89°F (2–4°F above normal)

  • Western Caribbean: 85–88°F

  • Main Development Region (MDR): Now reaching 82–84°F across much of the eastern Atlantic

Atmospheric Conditions

Wind Shear Courtesy of https://tropic.ssec.wisc.edu/

  • Wind Shear: Still elevated in the western Atlantic and Gulf, but beginning to weaken, particularly near Central America and the western Caribbean.

  • Moisture: Mid-level moisture continues to increase, especially in the Caribbean and southern Gulf.

  • Saharan Air Layer: A large, dry SAL continues to stretch across the central Atlantic, suppressing storm formation east of the Lesser Antilles, but it's expected to weaken by early August.

Thunderstorm & Rainfall Activity

  • Florida & Gulf Coast: Expect locally heavy rain and thunderstorm clusters tied to the Gulf disturbance.

  • Western Caribbean: Some disorganized convection continues, but nothing tropical at this time.

  • West Africa: A new tropical wave has emerged, but faces significant dry air and shear over the central Atlantic.

Florida Forecast

  • Highs: Upper 80s to low 90s°F

  • Humidity: High, with a heat index reaching the upper 90s

  • Rain: 60–70% chance of scattered storms in parts of Florida, especially in the afternoon and evening

  • Winds: Light southeast winds, with occasional gusts during storms

Prep Tip of the Day: Review Flood Insurance Coverage

Standard homeowners insurance does not cover flood damage. Use this calm window to:

  • Check your flood zone designation

  • Review your current policy limits

  • Confirm your coverage start date (flood insurance usually has a 30-day waiting period)

With warm SSTs and an increasingly favorable atmosphere, inland and coastal flood risk rises as we move deeper into hurricane season.

Looking Ahead: Watchful, Not Worrying

Although July 16 brings no immediate storm threats, all eyes remain on the broader Atlantic:

  • The ingredients for development are aligning: warm water, weakening shear, and increased moisture.

  • The next two weeks may see the first organized systems forming in the western Caribbean or Gulf of Mexico.

Now is the time to stay informed and finalize preparations—not when a storm is already on the map.

Atlantic Hurricane Outlook – July 15, 2025: Gulf System Organizing, Tropics on Alert

A weak low over Florida is drifting into the Gulf of Mexico, producing heavy rain and prompting close monitoring. While development chances remain low, record-warm waters and shifting winds suggest more activity is coming.

The Atlantic remains officially quiet, but eyes are turning toward the Gulf of Mexico as a broad area of low pressure continues to develop. Though not yet a tropical depression, this system is producing heavy rainfall across parts of Florida and may slowly organize over the next few days. Elsewhere, warm sea surface temperatures and improving atmospheric conditions continue to set the stage for increased activity as July progresses.

Atlantic Basin: Watching the Gulf

As of this morning’s update from the National Hurricane Center (NHC):

  • No named tropical cyclones

  • One area of interest: Disturbance near Florida

  • Development potential: Low over 48 hours (10%), Slightly higher over 7 days (20%)

A broad, weak surface trough stretching across southern Florida is generating scattered storms and heavy rainfall. As it drifts westward into the Gulf of Mexico, slight development is possible—though wind shear and dry air may continue to limit its growth in the near term.

Regardless of tropical classification, this system is expected to bring:

  • Heavy rainfall across Florida and the Gulf Coast

  • Localized flash flooding

  • Coastal thunderstorms and rough surf

Sea Surface Temperatures: Primed and Warming

Waters across much of the Atlantic basin are running well above average:

  • Gulf of Mexico: 87–89°F (30–32°C) across much of the basin—ideal for storm formation

  • Caribbean Sea: Persistently warm, with temperatures near or above 86°F (30°C)

  • Main Development Region (MDR): Trending well above average for mid-July

This level of ocean heat content supports rapid intensification potential for any system that organizes in the coming weeks.

Atmospheric Conditions: Becoming More Favorable

Wind Shear Courtesy of https://tropic.ssec.wisc.edu/

  • Wind Shear: Moderate across the Gulf and Caribbean, but forecast models show a gradual easing through late week

  • Moisture Levels: Improving, especially in the western Caribbean and southern Gulf

  • Upper-Level Winds: Starting to show a less hostile pattern over the Gulf and MDR

Overall, the atmospheric profile is trending toward neutral to favorable—a subtle but important change.

Saharan Air Layer (SAL): Retreating Slowly

Dry air remains across parts of the eastern Atlantic but is beginning to loosen its grip:

  • Still suppressing deep convection off the African coast

  • Expected to retreat westward and weaken through the next 7–10 days

  • This transition opens the door for tropical waves to survive and organize

Florida & Gulf Coast Forecast: Wet and Stormy

The disturbance currently over Florida is impacting much of the region:

Florida Peninsula

  • Scattered to widespread showers and storms today

  • Localized flooding possible, especially in urban areas

  • Highs in the upper 80s to low 90s°F

Northern Gulf Coast (AL/MS/FL Panhandle)

  • Cloudier skies and increasing storms through tomorrow

  • Elevated rainfall totals possible

  • Winds 10–20 mph with gusty thunderstorms

Prep Tip of the Day: Secure Outdoor Items

With storms increasing across the Southeast:

  • Bring in or secure loose outdoor items like patio furniture, garden tools, and trash bins

  • Clear storm drains and gutters to reduce urban flooding risk

  • Monitor flash flood alerts in flood-prone neighborhoods

Looking Ahead: A Pattern Shift Is Coming

Although no named systems are expected in the next few days, the Gulf disturbance is a reminder that even weak systems can cause significant impacts. Sea surface temperatures and weakening wind shear are setting the table for development in the latter half of July.
