Brazos Valley Under Flood Watch as Severe Storm Risk Escalates in Texas

A moist low-level jet is fueling repeated rounds of storms that threaten flooding with damaging winds across Southeast Texas before rainfall eases by weekend

Future weather radar models depicting Central and South Texas at 5 a.m., left, and at noon Wednesday, right, show storms developing along the Interstate 35 corridor.
Future weather radar models show storms moving across Central and South Texas at 5 a.m., left, and heading toward the Gulf Coast at 10 a.m. Thursday.
This flood risk outlook for Wednesday from the National Weather Service’s Weather Prediction Center gives the region in yellow, stretching across the eastern two-thirds of Texas, at least a 15% chance of flash flooding occurring.
Shown are potential cumulative rainfall totals through Friday in South Texas, according to the National Blend of Models.

Overview

  • The National Weather Service has placed the Brazos Valley north of Houston under a flood watch through Thursday evening as multiple storm clusters move through the region.
  • The Weather Prediction Center has flagged the Houston metro at a level 2 out of 4 flash flood risk with downpours of several inches possible in short periods.
  • The Storm Prediction Center has issued a slight risk for severe thunderstorms in Southeast Texas, warning of 60-mph gusts, hail up to 1 inch and isolated tornadoes.
  • Meteorologists say a moist low-level jet interacting with outflow boundaries will drive persistent heavy showers and thunderstorms, with some areas in northeastern Texas poised to receive a month’s worth of rain in two to three days.
  • Forecasts call for additional heavy rain through Friday, but models show flood threats should subside by weekend as storm strength gradually wanes.
