A Flood Watch remains in effect for parts of the Hill Country, I-35 corridor, southern Edwards Plateau, and Rio Grande Plains through Thursday evening. There is the potential for life threatening flooding somewhere in the watch area. There is a level Level 4 of 4 Risk (High) for flooding rain (today) for portions of the U.S. 90 corridor, west of San Antonio - including the southern Edwards Plateau, Rio Grande, and western Hill Country. Considerable to locally catastrophic flash flooding impacts likely in this region. Pockets of an additional 10-15 inches of rain in this region are possible. Storm totals across the rest of the area under the Flood Watch of 2 to 6 inches are possible. Stay weather aware and remember to have multiple ways to receive warnings.
Several rounds of showers and thunderstorms are likely at times through Thursday evening. Widespread additional amounts of 2-6" are possible across the Flood Watch area. Isolated additional amounts of 10-15" are possible mainly over the Rio Grande Plains, southern Edwards Plateau, and western Hill Country. Turn Around, Don't Drown. Have multiple ways to receive warnings and other weather information.
Never underestimate the power of water. Heavy rain can quickly cause flash flooding. Always use caution if camping near a stream, river, or low-lying area.
With more flooding possible late tonight into tomorrow morning on top of the considerable to locally catastrophic flooding experienced across portions of the region over the past two days, staying completely out of floodwaters is critical. Moving or standing water hides a multitude of active, invisible dangers that can lead to serious sickness, injury, or even death. These hidden hazards include displaced animals and stinging insects, active live wires, harmful bacteria, toxic chemicals, raw sewage, and sharp objects or debris hidden just beneath the surface.
Remember the difference between a Flood Watch and a Flash Flood Warning. A Flood Watch means conditions are favorable for Flash Flooding whereas a Flash Flood Warning means dangerous Flash Flooding is imminent or expected shortly.
