Key Points
1
Context on the season: The Atlantic’s fifth named storm typically forms by August 22, and the first Atlantic hurricane typically forms by August 11, with this season having had no hurricanes yet to date.
2
Dolly’s remnants weakened due to strong shear and dry air, reducing organization, and while Dolly’s remnants continue to influence rainfall, conditions are not expected to re-strengthen in the near term.
3
Current position and intensity of PTC Five: as of 10:00 AM CDT Aug 31, the center was near 27.8N, 91.0W, moving WNW at 5 mph, with maximum sustained winds around 35 mph and a central pressure near 1013 mb.
4
Geographic proximity: Invest 97-L is about 100 miles south of the Louisiana coast and is forecast to become Tropical Storm Edouard by this evening, with winds near 45 mph before landfall near the Texas/Louisiana border.

Forecast-model guidance is being actively updated, with references to spaghetti models and maps for tracking PTC Five, underscoring the range of possible tracks as the system evolves.
A tropical system bearing down on the Gulf Coast could develop into Tropical Storm Edouard as soon as Saturday evening, with the National Weather Service warning of heavy rain and gusty winds along the Texas-Louisiana border. The National Hurricane Center designated the system as Potential Tropical Cyclone Five on August 31, positioning it roughly 100 miles south of Louisiana and moving northwest at just 5 mph with maximum sustained winds near 35 mph.
Tropical Storm Warnings are in effect from Port Bolivar, Texas, to the Vermilion and Cameron Parish line in Louisiana. Forecasters expect wind speeds to peak around 45 mph before landfall, with flooding from heavy rainfall posing the primary threat to coastal communities as the season enters its peak danger period.
Two Storm Systems Threaten the Gulf
The Atlantic hurricane season, which runs June 1 through November 30, is tracking two active weather systems simultaneously. Potential Tropical Cyclone Five dominates forecasts for the immediate Gulf Coast threat, while Dolly's remnants continue soaking the Caribbean islands and approaching Florida. USA Today reports the National Weather Service has issued tropical storm and flood warnings for Houston and Galveston areas, signaling serious concern for the region.
Why This Storm Could Strengthen Quickly
As of 10:00 AM CDT on August 31, Potential Tropical Cyclone Five sat at coordinates 27.8°N, 91.0°W with maximum sustained winds around 35 mph and central pressure near 1013 millibars. The system is moving slowly westward at just 5 mph, giving it time to gather moisture over warm Gulf waters. Lubbock Online notes forecasters are tracking multiple model scenarios using spaghetti models—maps showing various possible storm tracks—to prepare for rapid intensification.
Dolly's Weakening Clears the Path
Tropical Storm Dolly's remnants have lost much of their punch after crossing the Caribbean. Strong wind shear and dry air broke apart the storm's organization as it approached the Greater Antilles, preventing re-strengthening. While Dolly will continue delivering rainfall to Hispaniola, Cuba, and the Bahamas, WOVK reports the National Hurricane Center expects no significant re-development in the near term, allowing forecasters to focus entirely on the Texas-Louisiana threat.
Heavy Rain the Real Danger at Landfall
Though wind speeds will remain modest at 45 mph, flooding from heavy rainfall represents the greatest hazard to coastal and inland communities. The Caller warns residents in the Houston-Galveston area that the slow-moving system could drop significant amounts of rain over 24 to 48 hours. The National Weather Service continues updating forecast models as the system approaches, urging residents to monitor official warnings and prepare for potential flooding in low-lying areas and along rivers downstream from heavy rainfall zones.
