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.

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.

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

Satellite imagery courtesy of Windy.com

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.

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.

Rainfall forecast (ECMWF) courtesy of Windy.com

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

Satellite imagery courtesy of Windy.com

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.

Relative Humidity data (ECMWF) courtesy of Windy.com


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

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

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

Radar imagery courtesy of Windy.com

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.

Stay tuned, stay prepared, and check back daily with Cat5Prep for accurate, actionable updates.

Atlantic Hurricane Outlook – June 20, 2025: Tropics Hold Quiet as Atlantic Patterns Begin to Shift

The Atlantic remains calm with no storms expected, but warm waters and shifting atmospheric patterns hint that the quiet may not last. A developing Atlantic Niña could hit a reversal and amplify activity later this season.

As we close out the third week of the 2025 Atlantic hurricane season, the basin remains quiet. No named storms or tropical disturbances are being monitored by the National Hurricane Center (NHC), and no development is expected over the next 7 days. However, behind this calm lies a subtle shift in Atlantic patterns that may influence storm activity in the weeks ahead.

Daily Hurricane Update June 20, 2025 with Hurricane formation in the Atlantic being suppressed by Atlantic Niña

Atlantic Basin: All Clear—for Now

As of the latest NHC update (8 AM EDT, June 20):

  • No active tropical cyclones

  • No areas of interest

  • No tropical development expected through late June

This type of quiet is typical for mid-June, historically a transitional period before activity ramps up in July and peaks from August to October.

Satellite view via Windy.com

Sea Surface Temperatures: Still Hot, Still Fuel

Sea surface temperatures (SSTs) across much of the Atlantic remain well above normal:

  • Gulf of America (Mexico): Mid to upper 80s°F (29–31°C), 2–4°F above average

  • Western Caribbean: Similar anomalies, particularly near the Yucatán and Cuba

  • Main Development Region (MDR): Still warming gradually, trending toward conditions that could support long-track storms later this season

Warm SSTs are a critical energy source for hurricanes—and the heat is already in place.

Sea Surface Temperature (ECMWF Analysis) via Windy.com

Atmospheric Conditions: Neutral ENSO, but Atlantic Cooling Briefly

While the Pacific remains in an ENSO-neutral phase, a rare “Atlantic Niña” has recently emerged—marked by cooler-than-average sea surface temperatures in the eastern tropical Atlantic off the coast of Africa, as seen in the NOAA Coral Reef Watch chart below with a pocket of blue.

  • This can temporarily suppress early-season hurricane formation by reducing convection and stabilizing the atmosphere

  • However, models indicate that this pattern may reverse in July, shifting into a warmer Atlantic Niño phase, which typically boosts tropical activity

So, while the Atlantic Niña may be limiting development now, forecasters are closely watching the timing of this transition. Safe money would be on a reversal, which could super charge storm breeding.

While no tropical organization is underway, convection continues to pop up in key regions:

  • Florida and Gulf Coast: Afternoon storms due to heat and humidity

  • Western Caribbean: Scattered convection, but unorganized

  • Eastern Atlantic: A few tropical waves exiting Africa remain weak and embedded in dry air

These thunderstorms are typical for the season and do not currently show signs of tropical development.

Thunderstorm Forecast (ECMWF) via Windy.com

Florida Forecast

  • Highs: Upper 80s to low 90s°F (31–33°C)

  • Humidity: High

  • Afternoon Storms: Scattered area of thunderstorms likely after 2 PM

  • Winds: Light and variable, with storm gusts possible

Flooding in low-lying areas is possible if storms linger over one area.

Rainfall Forecast (ECMWF) via Windy.com

Prep Tip of the Day: Restock Pet Supplies

Don’t forget your furry family members when preparing for hurricane season:

  • Have a two-week supply of pet food, medications, and water

  • Keep vaccination records and vet contact info in your go-bag

  • Prepare a small pet first-aid kit

  • Label pet carriers clearly and store them where they’re easy to grab

Looking Ahead: Transition Coming

For now, the Atlantic basin is calm. But forecasters continue to watch:

  • Warm SSTs

  • Easing wind shear

  • Gradual return of moisture

  • Potential reversal from Atlantic Niña to Atlantic Niño

All signs point to a more active environment forming as we move into July. Stay alert, stay prepared, and check back tomorrow for your daily hurricane outlook from Cat5Prep.com.

Atlantic Hurricane Outlook – June 19, 2025: Still Down South – Pacific Watches Erick

The Atlantic remains storm-free, but Hurricane Erick—a powerful Category 4 storm—gains strength in the Eastern Pacific. Learn what this means for the Atlantic basin and why now is the time to prepare.

The Atlantic basin remains quiet today, with no active tropical cyclones and no development expected over the next 7 days, according to the National Hurricane Center’s latest 2 AM and 8 AM EDT outlooks nhc.noaa.gov. While the Atlantic sleeps, attention is turning to a powerful system in the Pacific.

Atlantic Basin: Calm Waters, No Alerts

There are still no named storms or areas under tropical monitoring. The graphical and textual 7-day outlooks show zero development chance, meaning the basin continues its quiet stretch early in the season . Early June silence isn’t unusual—but with warm seas in place, conditions could shift quickly.

Satellite view via Windy.com

Pacific Perspective: Erick Now a Category 4

In the Eastern Pacific, Hurricane Erick has rapidly intensified into an “extremely dangerous” Category 4 storm with 145 mph sustained winds, now only about 70 miles west-southwest of Puerto Ángel, Mexico, heading for landfall.
This storm is expected to bring destructive winds, brutal rainfall (8–16 inches), mudslides, and severe coastal flooding across southern Mexico.


Sea Surface Temperatures: Atlantic Warming Continues

  • Gulf & Western Caribbean: SSTs remain warm at 84–88 °F, maintaining energy supply for potential tropical systems.

  • Main Development Region (MDR): Ocean temperatures are also above normal, setting the stage for Atlantic activity later in the season.

Atlantic Hurricane Outlook – June 1, 2025: Opening Day, But All’s Quiet… For Now

June 1 marks the official start of the 2025 Atlantic hurricane season. No storms are currently active, but rising sea surface temperatures and favorable patterns suggest a potentially busy season ahead.

The Atlantic hurricane season officially begins today, June 1, and while the tropics are currently quiet, forecasters are already eyeing the environmental conditions that could lead to a very active season. For residents in hurricane-prone regions, now is the time to prepare—not relax.

Atlantic Basin: Calm Start to the Season

As of the latest update from the National Hurricane Center (NHC), there are no active tropical systems, no areas of concern, and no immediate threats expected over the next seven days.

This quiet opening is not unusual. Early June often sees little activity in the deep tropics. However, this calm is not expected to last. Sea surface temperatures are running well above average, and the atmospheric setup is trending toward conditions favorable for development later this month.

Satellite data courtesy of Windy.com

Sea Surface Temperatures: Running Hot

The Atlantic basin is notably warm for this early in the season, providing more than enough fuel for potential tropical cyclones.

  • Gulf of America (Mexico): 2 to 4°F above normal, with widespread areas exceeding 86°F (30°C)

  • Caribbean Sea: Similar temperature anomalies, especially in the western basin

  • Main Development Region: Continues trending above average

Historically, warmer-than-average waters correlate with more frequent and intense storms.

Sea surface temperature data courtesy of Windy.com

ENSO Neutral: La Nada Takes Over

The El Niño–Southern Oscillation (ENSO) is now in a neutral phase. With El Niño in the rearview and La Niña not yet in play, we enter what meteorologists call "La Nada"—a neutral state that often removes inhibiting influences on hurricane formation.

  • Decreased wind shear is expected across the Atlantic basin

  • A neutral ENSO often correlates with average to above-average storm development

  • Other patterns, like the Madden–Julian Oscillation (MJO), may become more influential later in the month

Saharan Air Layer: Dust Still in Play

The Saharan Air Layer (SAL) continues to stream across the Atlantic from Africa, bringing with it dry, dusty air that temporarily suppresses tropical development.

  • Inhibits cloud formation and convection

  • Increases atmospheric stability

  • Introduces vertical wind shear

The SAL typically begins to weaken later in June, removing one of the key atmospheric barriers to tropical development.

Saharan Dust SAL data courtesy of Windy.com

Eastern Pacific: Alvin Weakens

Tropical Storm Alvin, the Eastern Pacific's first named storm of the season, formed earlier this week and is now weakening.

  • Location: Approximately 710 miles south of Baja California

  • Movement: Northwest at 13 mph

  • Maximum Winds: 50 mph, weakening

  • Forecast: Expected to dissipate within 36 hours

Though Alvin poses no threat to land, its formation signals that tropical systems are beginning to stir in the broader region.

Florida Forecast: Statewide Conditions Typical for June

Across the state of Florida, today's weather reflects classic early summer patterns.

  • North Florida: Highs in the upper 80s, lows in the mid-60s, low humidity, mostly clear skies

  • Central Florida: Highs near 90°F, afternoon humidity and a slight chance of thunderstorms

  • South Florida: Highs in the mid-80s, lows in the upper 70s, muggy with isolated afternoon storms

These are the kinds of conditions that typically precede the onset of more frequent tropical activity in late June and July.

Temperature across Florida data courtesy of Windy.com

Preparation Tips: Start Now, Not Later

With the season now officially underway, take time today to prepare while skies are still clear.

  1. Review your family emergency plan and evacuation zone

  2. Check and restock your hurricane kit

  3. Confirm your insurance coverage and take property photos

  4. Sign up for local emergency alerts and follow trusted forecast sources

  5. Bookmark Cat5Prep.com and the National Hurricane Center

Looking Ahead

Although the season begins on a quiet note, forecasters warn that this calm is likely temporary. Record sea surface temperatures, a neutral ENSO, and easing wind shear all point to increased tropical activity as we move deeper into June.
