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.

TL;DR
Atlantic Hurricane Forecast for July 27, 2025
No tropical storms are expected this week — the Atlantic remains quiet.
Three tropical waves are being monitored across the basin. None are showing strong signs of development yet.
Sea surface temperatures are hot and rising — especially in the Gulf and Caribbean — setting the stage for activity in August.
Wind shear and dry air (Saharan dust) continue to limit development for now.
Florida and the Gulf Coast: Typical summer weather—hot, humid, and scattered afternoon storms.
Prep Tip: Now is the time to stock up on essentials and finalize your hurricane communication plan.
No immediate threats, but stay alert. The quiet won’t last forever.
Atlantic Hurricane Outlook – July 20, 2025: Tropical Wave Parade Signals a Shifting Pattern
Multiple tropical waves are moving across the Atlantic, including a monitored disturbance near 40°W and a new wave off the African coast. While no tropical cyclones are active, conditions are being closely watched for signs of development.
As we close out the third week of July, the Atlantic remains without named storms—but activity is clearly on the upswing. Multiple tropical waves stretch across the basin, including a disturbance in the central Atlantic, a new wave off Africa, and a low near 08N44W. While none are close to development yet, we are seeing textbook signs of a transitioning pattern that could prime the Atlantic for August’s ramp-up.
Atlantic Basin: Watching Several Waves
As of the 8:00 AM EDT Tropical Weather Outlook and 0600 UTC Surface Analysis:
No active tropical cyclones
One area of interest with low development chances (20%): A tropical wave near 40°W continues to be monitored.
New tropical wave introduced: Near 23°W in the far eastern Atlantic (off Africa), moving westward with convection along its southern flank.
Low pressure near 08N44W embedded in the monsoon trough is helping spark convection.
Disturbance 1, the central Atlantic wave, continues to move westward at 10–15 knots. While still disorganized, it maintains scattered convection and remains under close watch. Other waves in the deep tropics—including the new one off Africa—will be tracked for organization over the coming week.
NOAA/NESDIS/STAR – GOES-19 Air Mass Composite – July 20, 2025
Sea Surface Temperatures: Warm and Welcoming
Ocean heat content remains very favorable:
Gulf of Mexico: 86–89°F (30–32°C)
Western Caribbean: Holding steady at 86°F+
Main Development Region (MDR): Near-to-above normal, especially between 30W and 50W
There is no shortage of storm fuel—the atmosphere just needs to catch up.

Wind Shear & Moisture: A Gradual Shift
Wind shear remains moderate in the central and western Atlantic, but is forecast to slowly ease.
Dry air from the Saharan Air Layer continues to impede vertical development of tropical waves, especially in the MDR.
Moisture is increasing around the Intertropical Convergence Zone and the Caribbean, a key precursor for storm organization.

Saharan Air Layer: Still in Control—for Now
The SAL remains widespread across the eastern and central Atlantic, with effects including:
Dry air entrainment disrupting convective growth
Stronger mid-level winds inhibiting vertical cloud development
This suppression is expected to loosen over the next 7–10 days, coinciding with climatological acceleration.

Monsoon Trough & Convection: Activity Percolating
A monsoon trough stretches from western Africa to near 46°W and supports scattered convection, particularly around 08N44W.
The new wave near 23°W is accompanied by moderate convection—early signs of organization.
Another tropical wave has now moved inland over Central America and is now being monitored in the East Pacific.

Gulf of Mexico: Typical July Pattern, But Shifts Ahead
A surface trough over the Bay of Campeche is causing showers and thunderstorms in the far southwestern Gulf.
Another weak trough across Florida is sparking isolated thunderstorms off the Gulf coast near Naples.
A weak high near the northeast Gulf continues to dominate.
Looking ahead:
Winds could increase by Thursday across the NE Gulf as broad low pressure moves across the southeastern U.S. and possibly into the northern Gulf.
Widespread showers and thunderstorms expected midweek across the east and north-central Gulf waters.

Caribbean Sea: Breezy and Stormy in the South-Central Basin
Fresh to strong NE to E winds continue in the south-central Caribbean, with seas of 8–11 ft.
Moderate to fresh trades elsewhere with 4–7 ft seas.
Scattered storms noted near Haiti, eastern Cuba, and Panama’s western coast.
A tropical wave expected midweek will bring enhanced shower and thunderstorm activity across the eastern Caribbean and Windward Passage.

Prep Tip of the Day: Start Prepping for August, Not Reacting to It
With the tropics on the edge of activity, now’s the time to get ahead:
Replenish your hurricane kit (water, food, medicine, power banks)
Make sure your contact list includes out-of-area family
Stay signed up for emergency alerts in your area
Looking Ahead: Calm Now, But the Tropics Are Flexing
Though no storms are imminent, tropical waves are increasingly active, sea temperatures are peaking, and dry air is slowly loosening its grip.
