National Weather Service has issued a flood watch for the areas of Central Texas hit most by the deadly flooding over Fourth of July weekend.

The flood warning is in effect until Tuesday, July 15, at 7 a.m. for the Frio River. NWS said that major flooding is forecast for the Frio River below Dry Frio, with the National Water Prediction Service predicting the river will hit 18.6 feet at around 5 p.m. The major flood stage for the Frio River is 17 feet.

A flood watch will remain in effect in Kerrville and the surrounding area — the epicenter of the July 4 damage that left at least 130 dead — until 7 a.m. Tuesday.

The Flood Watch in effect for parts of the southern Plains, including much of Oklahoma and Texas, was expanded southeast this morning to encompass areas that were hit hard by catastrophic and deadly flash flooding last weekend, including Kerr, Travis and Burnet Counties.

The official tally of storm-related deaths across Texas rose to 131 on Monday as authorities warned of yet another round of heavy rains 10 days after a Hill Country flash flood that transformed the Guadalupe River into a killer torrent.

Isolated rainfall up to 3 inches is possible through early Monday. Storms could be slow moving and quickly produce flash flooding.

A flood watch will go into effect for much of south Louisiana this week as a slow-moving low-pressure system heads toward the Gulf of Mexico, bringing with it the potential for downpours and flash flooding along the Gulf Coast.
