Rainfall totals surge in parts of Southeast Texas as flash flood alerts remain active
Heavy rainfall in Southeast Texas triggers flash flood warnings, with up to 10 inches reported in Matagorda County.
HOUSTON — Some parts of Southeast Texas saw up to 10 inches of rain on Thursday morning, prompting flash flood warnings and a Weather Impact Alert Day from the KHOU 11 Weather Team.
As of 7 a.m., Matagorda County had received the most rainfall, with radar and gauge estimates near 10 inches around the Blessing and Wadsworth areas. KHOU 11 Meteorologist Kim Castro described it as “close to a foot of rain in six hours,” adding that “this early morning has been dumping buckets, especially along the coastline.”
The flash flood threat remains high across multiple areas:
-
Central Matagorda County is under a Flash Flood Warning until 11 a.m. with rainfall totals between 2.5 and 5 inches already recorded. More storms are expected to arrive shortly.
-
Northeastern Harris County, northwestern Chambers County, and southwestern Liberty County were also under a Flash Flood Warning until 7:30 a.m., with 2 to 4 inches of rain already reported and 1 to 2 inches more possible.
Additional trouble spots include:
-
Wallisville Road: up to 5.5 inches of rain
-
Highway 90 near northeast Harris County: between 4 and 5 inches
-
East of Beltway 8, including Baytown, Barrett, and Cloverleaf, where another round of moderate rain is building in
“These rainfall rates are no joke,” Castro said. “We’re talking about blinding rain at rates of 2 to 3 inches per hour in some areas.”
The flood risk remains at Level 3 (Moderate) on a 1-to-4 scale for the day, meaning conditions are favorable for flash flooding, especially in areas that have already seen several inches of rainfall.
KHOU 11’s Weather Impact Alert remains in place until 4 p.m. Thursday, with additional storms likely through mid-morning before tapering off in the afternoon.
