Early Tuesday in Houston, skies were clear and temperatures were around 81°F, but the calm start will not last. Tropical Storm Edouard is expected to send widespread showers and thunderstorms into the area, with temperatures near 89°F before rain cools parts of the city into the low 80s. The bigger concern is water, not heat.
Heavy Rain Arrives Tuesday
Showers and thunderstorms are expected to increase through late morning and afternoon, with an 80% chance of rain for Houston and additional storms continuing into Tuesday night. Some areas could receive 1 to 2 inches overnight, while the heaviest rainbands elsewhere across southeast Texas could produce rainfall rates of 3 to 4 inches per hour and totals of 6 to 9 inches or more. The National Weather Service says the greatest flood risk is generally along and east of Interstate 45.
Flood Watch Covers Houston Area
A Flood Watch remains in effect through 7 a.m. Wednesday for much of southeast Texas, including Harris County and nearby communities. Rapid runoff could flood bayous, creeks, underpasses, low-lying streets and poor-drainage areas, with especially dangerous conditions where heavy bands stall. Drivers should never enter a flooded roadway, consistent with federal flood safety guidance.
Coastal Counties Face Stronger Storm Impacts
Tropical Storm Warnings are posted for Chambers County, the Bolivar Peninsula and southern Liberty County, where stronger winds and heavier rain are more likely. Houston-area winds should generally stay light, but gusts could become much stronger inside thunderstorms and near the storm’s rainbands. The forecast calls for little to no significant storm-surge impact across most of the metro area.
More Storms Follow Wednesday
Wednesday will remain unsettled, with showers and thunderstorms likely, a high near 91°F and heat index values reaching about 102. Rain chances continue Thursday and Friday, when highs should remain around 91 to 92 degrees, followed by somewhat lower storm chances over the weekend.
Saturday and Sunday are expected to be sunny at times with highs near 90 to 91, though afternoon storms remain possible. Labor Day should be mostly sunny and hotter, with a high near 93°F and only a slight chance of an afternoon shower or thunderstorm.
