TLDR Version: Click Here
Current Tropical Systems
Hurricane Erin:
Erin has weakened slightly but remains a Category 2 hurricane as it tracks northeast, well offshore of the U.S. East Coast. The storm continues to generate dangerous swells, rip currents, and pockets of coastal flooding, especially from the Outer Banks northward into the Mid-Atlantic and New England. While direct landfall is not expected, coastal impacts remain significant.Disturbance in the Central Atlantic:
A tropical wave near 45°W continues to show signs of organization. Environmental conditions feature warm sea surface temperatures but are partially offset by moderate wind shear and Saharan Air Layer (SAL) dust intrusion. Development chances: 30% over 7 days.Far Eastern Atlantic Wave (off Africa):
A fresh wave near 25°W is emerging with scattered convection. It remains disorganized but will be monitored as it progresses westward. Development chances: low (20% over 7 days).
Gulf of America (Mexico) Outlook
The Gulf remains broadly quiet, with high pressure dominating and keeping conditions mostly stable. While moisture pockets are leading to afternoon thunderstorms, there are no signs of tropical development at this time. Sea surface temperatures are very warm (29–31°C), so the region will continue to be monitored closely heading into late August.
Florida Forecast
Florida remains under the influence of high humidity and afternoon sea-breeze thunderstorms, typical for August. Outer rainbands from Erin are not expected to impact the peninsula. No immediate tropical threats are forecast for the state in the near term.

Key Environmental Factors
Sea Surface Temperatures (SSTs): 29–31°C across the Gulf and Caribbean, MDR slightly above average — supportive for development.
Wind Shear: Moderate over the central Atlantic, helping limit wave organization.
Moisture: Gradual increase in the western Atlantic, but SAL dust continues to suppress deep convection in parts of the MDR.
Outlook Summary
Hurricane Erin remains a strong offshore system, generating significant surf and rip currents along the East Coast.
Central Atlantic disturbance carries moderate development potential but faces shear and dust challenges.
Gulf of Mexico and Florida remain calm with no immediate tropical concerns, though warm waters warrant close monitoring later this month.
TL;DR
Hurricane Erin is now a Category 2 offshore system, still driving dangerous surf and rip currents up the East Coast. The Gulf of Mexico and Florida stay quiet with only scattered thunderstorms, while the central Atlantic wave shows some development potential but is being held back by wind shear and Saharan dust.
Atlantic Hurricane Outlook – August 10, 2025: Multiple tropical waves crossing the Atlantic; development chances gaining
Multiple tropical waves are moving across the Atlantic today, but Saharan dust, wind shear, and dry air are keeping development chances low. Warm ocean temperatures could allow for changes later this week.
Atlantic Basin Overview
TLDR Version; Jump Here
As of this morning, no named tropical cyclones are active in the Atlantic. Several tropical waves are traveling westward across the Main Development Region (MDR), but most are struggling with environmental challenges that limit development. Sea surface temperatures are amply warm, so these waves will continue to be monitored as they move toward more favorable conditions later this week.
Key Systems We’re Watching
Central Atlantic Tropical Wave (~40°W):
Moving west at 10–15 knots with scattered convection. Organization remains limited due to dry air and moderate wind shear. Low chance of development over the next 7 days.Eastern Atlantic Tropical Wave (~23°W, off Africa):
Recently emerged from the continent with convection along its southern flank. Battling Saharan dust and dry air, keeping development chances low in the near term, potentially gaining strength in next 7-days.Monsoon Trough Low (~08N44W):
Embedded within the monsoon trough, sparking intermittent thunderstorm activity. No immediate signs of organized development.

No active tropical storms in the basin.
Two areas are now under National Hurricane Center scrutiny:
Invest Area AL95: Expected to be a fish storm, it’s a non-tropical low just off the North Carolina coast—producing disorganized thunderstorms. (The orange X on the chart)
➤ Chance of development: Medium (30%) over the next 2–7 days.
➤ Movement: Toward the east-northeast at ~10 mph, expected to stay offshore.Emerging tropical wave off Africa: Near 30°W, forecast to move westward with scattered convection.
➤ Chance of development: Low (30%) within 7 days.
GOES-19 - Sector view: North Atlantic - Sandwich - August 3, 2025
GOES-19 - Sector view: Tropical Atlantic - Sandwich - August 3, 2025
Key Environmental Conditions
Sea Surface Temperatures (SSTs):
The Gulf of Mexico and Caribbean Sea remain very warm, with temperatures ranging from 29–31°C (84–88°F). The Main Development Region (MDR) is also running slightly above average. These warm waters provide abundant fuel for tropical development — if other atmospheric factors allow.Wind Shear:
Moderate to high vertical wind shear persists across the central Atlantic, particularly along the latitude band where Disturbance 2 is located. This disrupts the vertical alignment of developing systems and limits the ability of convection to consolidate around a center.Moisture:
Mid-level moisture is gradually increasing across the western tropical Atlantic and Caribbean. However, the central Atlantic remains drier overall, especially in areas affected by Saharan dust, limiting deep convection and thunderstorm persistence.Saharan Air Layer (SAL):
A robust SAL is sweeping across the central and eastern Atlantic, characterized by dry, dusty air and suppressed vertical motion. The SAL also contributes to a stable atmosphere, effectively capping thunderstorm development and working against tropical wave organization.
Implication for Disturbance 2:
While ocean temperatures are favorable, the combined influence of high wind shear, limited moisture, and widespread SAL intrusion is expected to stall or inhibit further development of Disturbance 2 as it continues westward across the tropical Atlantic. Until it reaches a more favorable environment, organization remains unlikely.
Gulf of America (Mexico) & Caribbean Region
No disturbances active in the Gulf, and high-pressure conditions support light winds and minimal rain outside normal sea‑breeze showers.
Eastern Caribbean: A wave near 68°W is producing localized storms over Hispaniola and Venezuela but remains disorganized.

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.
