Tropical Storm Edouard strengthened Tuesday as it closed in on the Texas-Louisiana coastline, bringing an increasing threat of flash flooding, strong winds and storm surge to the northwestern Gulf Coast.
At 11:00 a.m. CDT on September 1, the National Hurricane Center placed Edouard near 29.5°N, 93.4°W, approximately 20 miles (30 km) south-southwest of Cameron, Louisiana, and 40 miles (65 km) east-southeast of Port Arthur, Texas.

Maximum sustained winds had increased to 50 mph (85 km/h), with the storm moving northwest at 8 mph (13 km/h). Its minimum central pressure had fallen to 1000 hPa.
Radar from Houston and Lake Charles showed the compact storm becoming better organized as it approached land.
Heavy rain is Edouard’s main threat
While Edouard is producing tropical storm-force winds near its center, flooding could become the storm’s most widespread hazard.
Forecast rainfall totals of 3 to 6 inches (75–150 mm) are expected across portions of southeast and east-central Texas and southwest Louisiana, with isolated totals approaching 9 inches (230 mm).
The heaviest rain is expected beneath persistent tropical rainbands, where thunderstorms could repeatedly cross the same locations.
This process, known as training, can produce dramatically different rainfall totals across relatively short distances. One community may receive manageable rainfall while another nearby experiences several hours of torrential rain and rapidly developing flash flooding.
The risk extends inland from the immediate coastline, including areas east and northeast of Houston.
Storm surge threatens the coastline
Edouard is also pushing Gulf water toward the coast.
Storm surge could raise water levels by approximately 3 to 5 feet (0.9–1.5 m) above normally dry ground in the most vulnerable coastal locations near the Texas-Louisiana border.
Low-lying communities around bays, passes and tidal waterways face the greatest risk, particularly if the peak surge coincides with high tide.

Strong winds could also bring down trees and power lines near the storm’s path. Tropical storm-force winds are concentrated relatively close to Edouard’s compact center, making the exact landfall location important for determining where the strongest gusts occur.
Schools close as Texas prepares
Preparations accelerated across southeast Texas as the storm approached.
Numerous Houston-area school districts cancelled classes Tuesday, while others announced early dismissals or suspended after-school activities because of the threat from flooding and strong winds.
Emergency resources were placed on standby, while utility crews prepared for possible power outages.
The preparations reflect particular concern about road flooding. Tropical rainbands can overwhelm drainage systems quickly, creating dangerous conditions during the afternoon and evening commute.
Why is Edouard strengthening?
Edouard developed over the exceptionally warm waters of the northwestern Gulf of Mexico, where abundant ocean heat provides energy for tropical thunderstorms.
The storm also encountered an environment increasingly favorable for organization as it approached the coast.
Thunderstorms consolidating around Edouard’s circulation have helped lower its central pressure and strengthen winds. Hurricane Hunter aircraft and coastal radar confirmed the intensification Tuesday morning.
However, Edouard has very little time remaining over water.
Its compact size means changes in thunderstorm organization can still produce relatively rapid fluctuations in intensity immediately before landfall, but interaction with land will soon cut off the storm’s oceanic energy supply.
Flood threat continues after landfall
Edouard is expected to cross the Texas-Louisiana coastal region later Tuesday before weakening inland.
Landfall will end the storm’s opportunity for further tropical intensification, but it will not immediately end the primary hazard.
Deep tropical moisture will continue moving inland with the circulation, allowing heavy rainbands to persist across southeast and east-central Texas and portions of Louisiana into Wednesday.

The first one could form TODAY, 40 miles off Louisiana.

The combination of slow movement, repeated rainbands and extremely moisture-rich tropical air means flash flooding may remain a concern well after Edouard’s center crosses the coastline.
For communities near the Texas-Louisiana border, the next several hours will bring the greatest combination of wind and coastal hazards, while the rainfall threat is likely to last considerably longer.
