As the final days of July unfold, the Atlantic basin remains active with several tropical waves but no immediate threats. While sea surface temperatures and atmospheric moisture continue to support development, upper-level wind shear and dry air are keeping conditions broadly stable—though this pattern may shift as we enter August.

Atlantic Basin: Multiple Waves, No Cyclones (Yet)

As of 8:00 AM EDT from the National Hurricane Center:

  • No active tropical cyclones

  • Two tropical waves are under watch:

    • Tropical Wave 1: Located near 40°W, moving westward at 10–15 kt with scattered convection. Still disorganized but under observation.

    • Tropical Wave 2: Recently emerged off Africa near 23°W, with convection along its southern flank. It’s embedded in a moist environment and will be monitored for future development.

  • No development expected over the next 7 days, but long-range models suggest increasing favorability for late next week.

Gulf of Mexico: Moisture Returns, But No Development

  • A weak surface trough lingers in the Bay of Campeche, producing isolated showers and thunderstorms.

  • No signs of tropical development at this time.

  • Expect scattered showers and storms across the eastern and central Gulf through Tuesday, driven by daytime heating and lingering mid-level moisture.

Caribbean Sea: Typical Summer Conditions

  • Fresh to strong trades continue in the central and southwest Caribbean, particularly off the coasts of Colombia and Venezuela.

  • Some isolated thunderstorms are active near Panama and the Windward Passage.

  • A tropical wave moving through the eastern Caribbean is enhancing convection, but remains disorganized.

Atlantic Main Development Region (MDR): Slowly Activating

  • Sea surface temperatures (SSTs):

    • MDR: 28–29°C (82–84°F), well above climatological norms.

    • Gulf and Caribbean: 30–31°C (86–88°F), fuel-ready.

  • Saharan Air Layer (SAL): Dry air continues to suppress convection over much of the MDR, but signs show it is beginning to weaken, allowing thunderstorm clusters to persist longer.

  • Wind shear: Still present in the central Atlantic, but trending downward.

Atlantic Hurricane Outlook – July 27, 2025: Calm Conditions Continue Despite Active Waves

The tropics stay quiet on July 27, 2025, but tropical waves in the deep Atlantic are being closely monitored. No development is expected in the next 7 days, but changes could come as we approach August.

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

The Atlantic basin remains free of named storms this morning, with no tropical cyclone formation expected over the next seven days. However, meteorologists are closely monitoring several tropical waves in the deep eastern Atlantic that could signal a developing pattern as we head into August.

Atlantic Basin: Quiet—but Watchful

  • No active tropical cyclones in the Atlantic basin.

  • The National Hurricane Center (NHC) reports that no tropical development is expected over the next 7 days.

  • Tropical waves in the eastern and central Atlantic continue to be monitored for organization.

Gulf of Mexico and Caribbean: No Significant Activity

  • No low-pressure disturbances currently under watch.

  • Conditions in the Gulf remain stable, with typical afternoon thunderstorms but no signs of tropical development.

  • Lower Caribbean waters remain under fresh easterly trade winds, with rather isolated convection near Central America.

Tropical Waves: Deep Atlantic Features to Monitor

According to the NHC’s Tropical Weather Discussion:

  • A tropical wave near 27°W (south of 17°N) is moving west at ~10 kt, with scattered moderate convection noted between 5°N and 9°N.

  • A stronger wave near 54°W (south of 22°N) is moving west at 15–20 kt, with scattered convection between 5°N–23°N.

  • An area of low pressure embedded in the monsoon trough near 8°N44°W is also aiding scattered convection but remains disorganized.

None of these systems currently have the structure required for classification, but they inhabit regions where sea surface temperatures and wind shear may soon become more conducive to development.

Environmental Conditions Snapshot

  • The Saharan Air Layer (SAL) remains strong across the eastern Atlantic, suppressing mid-level moisture and convection.

  • Wind shear in the central Atlantic remains moderate to high, limiting tropical organization—though forecasts suggest a gradual reduction heading into early August.

  • Sea surface temperatures across the Main Development Region (MDR) remain above average, providing energy should conditions improve later this month.

Florida Forecast

  • Highs around 90 °F with coastal humidity making it feel hotter.

  • Rain Chance: 40–50% for scattered afternoon thunderstorms driven by sea breeze convergence.

  • Winds: Light and variable, shifting to southeasterly in the afternoon.

  • No tropical impacts expected today.

Prep Tip of the Day: Check Your Weather Apps and Alerts

While the tropics are quiet, confirming your local alert settings and weather tool readiness can make all the difference:

  • Enable push notifications for National Hurricane Center advisories.

  • Confirm alert registration with your county emergency system.

  • Test weather apps and bookmarks on all household phones and devices.

Looking Ahead: August May Bring Change

Though today’s conditions remain tranquil, the presence of several tropical waves moving into warmer Atlantic waters—combined with weakening Saharan dust and decreasing wind shear—suggest a gradual shift toward a more active setup. Historically, the first week of August often kicks off heightened tropical activity.

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.

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.

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.

Prep Tip of the Day: Know the Early Signs

With deeper Atlantic activity beginning, now is a good time to refresh your awareness:

  • Follow NHC's five-day outlooks

  • Understand what “low chance” really means—it can change fast with heat and time

  • Review your emergency communication plan and make sure alerts are enabled

Looking Ahead: Watch the MDR

While Disturbance 1 may or may not develop, its emergence from the Cabo Verde region is a signal that the deep tropics are beginning to stir. Expect more waves in the coming weeks as we approach the climatological ramp-up of hurricane season.
