Atlantic Hurricane Outlook – July 24, 2025: Gulf Disturbance Monitored as Tropics Remain Broadly Quiet

A weak disturbance in the Gulf of Mexico brings rain to the Gulf Coast, but tropical development chances remain low. Meanwhile, the broader Atlantic remains quiet.

As we near the close of July, the Atlantic remains largely stable, but the National Hurricane Center is monitoring a weak disturbance in the Gulf of Mexico for any signs of development. While conditions remain broadly unfavorable for rapid formation, subtle shifts in the atmosphere suggest we’re approaching a more active phase of the season.

Atlantic Basin: Broad Stability, But Eyes on the Gulf

As of the 8:00 AM EDT Tropical Weather Outlook, the National Hurricane Center (NHC) is reporting:

  • No active tropical cyclones

  • One disturbance in the Gulf of Mexico with low development chances

  • No tropical cyclone formation expected elsewhere over the next 7 days

NOAA/NESDIS/STAR – GOES-19 Air Mass Composite – July 24, 2025

Gulf of Mexico: Surface Trough Brings Rain, Low Development Risk

A broad surface trough located over the north-central Gulf of Mexico is generating scattered showers and thunderstorms. While upper-level winds remain hostile to development, the NHC notes this system could persist for several days as it drifts slowly westward.

  • Formation chance (7 days): Low (near 10%)

  • Main impacts: Localized heavy rain along portions of the Gulf Coast (especially Louisiana, Mississippi, and Alabama)

  • Conditions: Disorganized thunderstorm activity, no defined surface circulation

Expect periodic showers and thunderstorms over coastal waters and possible heavy rainfall inland through the weekend.

Atlantic Hurricane Outlook – July 23, 2025: Gulf Disturbance Brings Rain Risk, Tropics Mostly Stable

A low-pressure system in the north-central Gulf is bringing rain to Florida and the northern coast, but development remains unlikely. Multiple waves in the Atlantic are being monitored.

The Atlantic basin remains quiet overall, but a new area of interest has developed in the north-central Gulf of Mexico, with a low (10%) chance of tropical development. Elsewhere, multiple tropical waves continue their westward journey across the Atlantic, but none show signs of immediate organization.

Gulf of Mexico: Watching a Coastal Disturbance

As of the 8:00 AM EDT update from the National Hurricane Center, a trough of low pressure just offshore the southeastern United States is producing disorganized showers and thunderstorms over the north-central Gulf. The system is forecast to drift west-southwestward over the next day or two into more open waters.

  • Chance of development remains low (10%) as the system will likely move inland before organizing.

  • Regardless of development, locally heavy rain is expected along the Florida west coast and the northern Gulf coast through the weekend.

We'll continue to monitor this system closely for any signs of improvement in structure.

Atlantic Hurricane Outlook – July 22, 2025: Tropics Stirring, But Development Remains Gradual

Tropical activity is picking up across the Atlantic, with multiple waves being monitored. While no storms are expected yet, conditions are slowly becoming more favorable for development.

The Atlantic basin remains free of named storms this morning, but the deep tropics are showing increased activity. Multiple tropical waves are marching across the basin—some with disorganized convection, others with early signs of circulation. While none are forecast to develop imminently, the atmospheric stage is being set for a more active period as we approach late July.

Atlantic Basin: Several Waves Under Watch

As of the 8:00 AM EDT Tropical Weather Outlook from the National Hurricane Center (NHC):

  • No active tropical cyclones

  • Two tropical waves of interest:

    • Central Atlantic wave near 45°W: Still disorganized, no longer showing on NOAA Seven-Day TWO , moving westward at 10–15 knots. Scattered convection continues, and models suggest a more favorable environment as it approaches the Caribbean later this week.
      Chance of development over 7 days: Low (20%)

    • Far Eastern Atlantic wave near 27°W: Recently emerged off Africa. Some associated convection along its southern flank, but no signs of organization yet.

Both systems are embedded in the broader Monsoon Trough, which is supporting shower and thunderstorm development across the deep tropics.

Sea Surface Temperatures: Favorable and Climbing

Ocean waters remain well above average in key areas:

  • Gulf of Mexico: 86–90°F (30–32°C) across most of the basin

  • Western Caribbean: Steady warming, ideal for storm fuel

  • Main Development Region (MDR): 1–2°C above normal across much of the eastern and central Atlantic

These conditions provide a supportive foundation for any systems that organize over the coming weeks.

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

Relative Humidity (ECMWF) data courtesy of Windy.com

Saharan Air Layer: Still an Inhibitor

Dry, dusty air continues to stretch across much of the central and eastern Atlantic. It:

  • Reduces storm cloud organization

  • Increases atmospheric stability

  • Weakens convection associated with tropical waves

SAL is expected to persist into early August but may begin to recede gradually.

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

Thunderstorm Activity: Isolated and Mostly Local

  • Florida: Scattered PM thunderstorms expected—typical for this time of year

  • Gulf & Western Caribbean: Moisture lingers but no signs of tropical organization

  • Off Africa/Central Atlantic: Activity is tied to Disturbance 1, but convection remains weak

Thunderstorm forecast (ECMWF) courtesy of Windy.com

Florida Forecast

  • Highs: Upper 80s to low 90s

  • Humidity: High

  • Rain: Isolated to scattered afternoon storms

  • Winds: Light to moderate easterlies

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.

Relative Humidity (ECMWF) data courtesy of Windy.com

Wind Shear July 18, 2025

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.

Rainfall forecast (ECMWF) courtesy of Windy.com

Florida Forecast: Humid and Storm-Prone

Expect classic July conditions across the state:

  • North Florida: Highs in the low 90s, partly cloudy, isolated afternoon storms

  • Central Florida: Around 91°F, muggy, with widespread PM storms

  • South Florida: Mid-to-upper 80s, very humid, storms possible after 2 PM

Local flooding is possible in poor drainage areas due to repeated rounds of heavy showers.

Thunderstorm forecast (ECMWF) courtesy of Windy.com

Prep Tip of the Day: Review Evacuation Zones

Now is the time to double-check your local evacuation zone and routes:

  • Know whether you're in a surge or flood-prone area

  • 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.

Check back tomorrow for the next update from Cat5Prep.com.

Atlantic Hurricane Outlook – July 17, 2025: Gulf Disturbance Brings Rain Threat, Development Chances Remain Low

A weak system in the Gulf of Mexico—Invest 93L—is bringing heavy rain and storms to the Gulf Coast. Tropical development remains unlikely, but flooding risks persist. The rest of the Atlantic basin stays quiet… for now.

The Atlantic basin remains free of named tropical cyclones today, but a weak low-pressure system—Invest 93L—continues to bring rain and thunderstorms along parts of the Gulf of Mexico coast. While the system is unlikely to develop into a named storm, the primary concern is heavy rainfall and flash flooding across coastal regions from Florida to Louisiana. The rest of the basin remains quiet, but conditions are slowly trending toward increased activity.

Atlantic Basin: Quiet But Not Completely Clear

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

  • No active tropical cyclones

  • One area of interest: Invest 93L

  • Development odds remain low—about 30% over the next 7 days

  • No other tropical development expected across the Atlantic basin through the week

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.
