HOUSTON – A Flash flood watch remains in effect through Friday evening for much of Southeast Texas with Fort Bend, Colorado, Austin and Waller Counties added to Galveston County (including the Bolivar Peninsula). A flash flood warning has been issued for Matagorda, Wharton and Jackson counties. Heavy rain is once again expected to kick off more flash flooding near Rockport and areas closer to the Houston Metro.

Friday:

Deep tropical moisture continues to be in place along the coast through the day. That, combined with a low-pressure system positioned in South Texas, will promote periods of heavy rain, although later today, according to our KPRC Futurecast model, the heaviest of the rain will begin to taper off a bit.

Rainfall totals Friday could exceed 10 inches -- in already waterlogged areas -- from between Matagorda Bay and Corpus Christi. Closer to Galveston, rainfall is expected to be between two and four inches. Flash flooding is possible near Brazoria and Galveston coastlines, but less likely than down the coast.

More heavy rain is possible down along the coast

The Weekend:

The disturbance over South Texas will drift west into Mexico and diminish in strength this weekend, which will lower our rain chances. A few typical summer afternoon showers and storms will still be possible, but the threat for heavy rainfall and flash flooding will be squelched.
