Most of southeast Texas will be under a flash flood watch from Friday afternoon to Saturday morning, according to the National Weather Service Houston/Galveston office.
Heavy rainfall is most possible from 6 p.m. Friday to 9 a.m. Saturday, with the hardest hit areas expected to be northwest of Houston and south of College Station, meteorologists said.
The flash flood watch will be in effect, however, from noon Friday to noon Saturday. Almost all of southeast Texas is encompassed in the watch, including Brazoria, Galveston, Harris, Montgomery, Waller, Fort Bend and Chambers counties.
An incoming cold front and storm system will move west to east over the area, producing the rain. Three to 6 inches of rain are expected over most of the area, with isolated spots receiving as much as 8 to 10 inches, meteorologists said.
The rainfall will clear from west to east on Saturday and should be off the coast by Saturday afternoon.
The National Weather Service has warned that isolated flash flooding could occur around area roadways, underpasses, low lying areas, and small creeks and tributaries.
