FORECAST

MORNING UPDATE:

The heavy rainfall west of San Antonio has again cranked up this morning. Flood warnings have been posted for large portions of the Highway 90 area and into the Hill Country. Another round of heavy rain looks poised to lift north into the area later this morning. We are monitoring the situation, as well as river levels. So far, rivers, while moving at fast rates, have only risen to minor flood stage. This could change rapidly, so those along rivers and creeks need to remain vigilant.

5:25 AM Update:

Heavy rain is moving into Medina and northeastern Uvalde County. These areas have already received 3″ to nearly 12″ of rain in the past 24 hours. This developing line of storms is steadily moving north and will be impacting Hondo, Castroville, Medina Lake, and Bandera very soon. Additional scattered storms are developing near Coastal areas.

REST OF TODAY

The flood risk will stay in place from San Antonio and points west through tonight. At any point, torrential rainfall and flooding could take place. A decrease in activity will likely occur this afternoon, but as it has been, more heavy rainfall may develop Wednesday night and into Thursday morning.

DRIER WEATHER THIS WEEKEND

Drier weather will take over by Saturday and Sunday.
