Atlantic Hurricane Outlook – July 29, 2025: Active Waves, Quiet Forecast

Several tropical waves are moving across the Atlantic, but none show signs of imminent development. Warm waters persist, and August may bring change.

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

Though the Atlantic basin remains free of tropical cyclones, several tropical waves are shifting across the ocean—each monitored for organization. Conditions remain broadly unfavorable for development, but the warm ocean and evolving atmospheric patterns suggest potential change in the weeks ahead.

Atlantic Basin: No Cyclones, But Several Waves in Motion

According to the latest Tropical Weather Outlook, the National Hurricane Center does not expect any tropical cyclone formation during the next seven days. However, recent Tropical Weather Discussion reveals:

  • A tropical wave near 19°W (south of 19°N), moving westward at about 10 kt, with scattered convection between 10°N–13°N and east of 23°W.

  • Another wave near 38°W, south of 18°N, moving slowly (~5 kt), associated with a 1012 mb low. A scatterometer pass noted fresh to strong winds within 120 nm and scattered convection between 5°N–12°N.

None of these features currently exhibit a closed circulation or organization, but their movement into warmer waters bears monitoring.

Gulf of Mexico & Caribbean: Calm Signals, Minimal Development Risk

  • No disturbances are being tracked in the Gulf at this time.

  • Surface analyses and satellite imagery show mostly typical trade-wind patterns and minor convection near Central America and the Windward Passage.

  • A dominant high-pressure ridge maintains light to moderate winds and minimal seas across most of the region.

Environmental Snapshot: Barriers Remain, Fuel Accumulating

  • Sea surface temperatures across the Gulf of Mexico and western Caribbean are well above average, delivering ample heat energy for potential development in early August.

  • The Saharan Air Layer (SAL) continues to suppress convection in the eastern Atlantic. Convection in tropical waves remains shallow and short-lived.

  • Upper-level wind shear remains moderate to high, especially over the central MDR, limiting vertical storm organization.

Prep Tip of the Day: Keep Monitoring Those Waves

Even when storms don’t form, their precursors still matter:

  • Review evacuation zones and routes now—not during an emergency.

  • Check the status of local email lists or alert systems for tropical watches.

  • Confirm your household has working weather radios and updated contact lists.

Looking Ahead: August May Bring Increased Activity

While development is unlikely in the next 5–7 days, the combination of:

  • Warm ocean temperatures,

  • Decreasing wind shear projections, and

  • Multiple tropical waves entering the MDR

suggests the system is slowly shifting toward a more favorable environment as August begins.

TL;DR

Flood‑ready outlook for July 29, 2025

  • No tropical cyclones in the basin; no development expected this week.

  • Two tropical waves showing scattered convection—watching for mid‑Atlantic changes.

  • Warm Gulf and Caribbean waters offer fuel if shear and dry air ease up.

  • Florida sees typical summer weather—heat and scattered afternoon storms.

  • Prep recommendation: finalize hurricane plans, stay informed, remain ready.

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

Atlantic Hurricane Outlook – June 4, 2025: A Flicker on the Horizon

Though no storms are active, key hurricane ingredients are aligning fast. A developing low near the Southeast U.S. and rising SSTs suggest change is coming.

The fourth day of the 2025 Atlantic hurricane season opens with quiet skies—but a subtle shift is underway. For the first time this season, the National Hurricane Center (NHC) has flagged a potential area of interest offshore the southeastern United States. While development chances remain low, it’s a reminder that conditions are evolving and the atmosphere is beginning to stir.

Daily Hurricane Update June 4, 2025

Atlantic Basin: A New Watch Zone Emerges

As of this morning’s Tropical Weather Outlook from the NHC:

  • No active tropical cyclones

  • One area of interest off the Southeastern U.S. coast

  • No tropical development expected in the next 48 hours

  • Low (10%) chance of development over the next 7 days

A non-tropical low pressure area is forecast to form near or offshore the Southeast U.S. coast.

If it remains offshore, it may gradually acquire subtropical or tropical characteristics while drifting northeastward at 10–15 mph.

NHC Forecaster Reinhart, June 4, 2025

No storm is expected soon—but it’s the first official mention of potential development this season.

Sea Surface Temperatures: Ready for Action

Warm waters across the Atlantic basin continue to deepen—creating an ideal foundation for future storm formation:

  • Gulf of Mexico: Running 2–4°F above average, with pockets exceeding 86°F (30°C)

  • Western Caribbean: SSTs remain high, particularly around Central America and Cuba

  • Main Development Region (MDR): Trending warmer than normal with gradual warming expected into late June

This warm ocean water is the primary energy source for hurricanes—and it’s already in place.

Wind Shear & Moisture: Storm Barriers Continue to Erode

Atmospheric conditions are shifting in a storm-friendly direction:

  • Wind shear is weakening in key zones like the Gulf and Caribbean

  • Moisture levels are rising at both low and mid-levels of the atmosphere

  • Vertical instability is increasing, supporting larger, longer-lasting thunderstorms

This transition increases the likelihood that disorganized storms could become organized systems.

Wind Shear June 4, 2025

Saharan Air Layer: Still a Barrier, But Fading

A broad plume of Saharan dust remains in the central and eastern Atlantic, offering temporary protection:

  • Suppresses convection

  • Inhibits thunderstorm growth

  • Raises wind shear and dry air intrusion

However, models show this SAL influence weakening by mid-to-late June, removing one of the final natural inhibitors.

Thunderstorm Activity: Early Clues

Even in the absence of tropical storms, convective activity gives us clues about what's forming:

  • Western Caribbean & Bay of Campeche: Disorganized clusters of thunderstorms show signs of persistent convection

  • Southeastern U.S. Coast: Isolated convection associated with the developing non-tropical low

While nothing is organizing yet, this pattern often precedes early-season development.
