SAN ANTONIOUPDATE: As of Tuesday morning, pockets of up to 7 inches of rain have fallen in west and northwest Bexar County, leading to dangerous flash flooding.

Flood Safety

It is never a good idea to drive during a flash flood warning. If you can stay home during a flash flood event, please do. Just 6 inches of rushing water can knock down a person, and 12 inches of rushing water will sweep away most cars. If you come across a flooded road, remember: TURN AROUND, DON’T DROWN


(Original Story)

The city of San Antonio usually by July has already reached its first 100 degree day. This year, an unusually wet summer weather pattern will bring daily rain chances for the first full week of July and keep temperatures cooler than average. Here is what you need to know:

  • A low pressure system will produce daily scattered showers and storms through the end of the week.
  • Most will experience heavy rain with lightning, producing 1.00″ to 3.00″ of rainfall. This could lead to minor flooding.
  • A few folks will receive very heavy rains - leading to some spots of 5.00+″ of rain by the end of the week. That would likely prompt flash flood warnings.

Weather Safety

You’ve probably heard the KSAT Weather Authority Team say, “When thunder roars, go indoors!” With storms in the forecast over the next few days, you’ll need to be ready to move your summer outdoors plan indoors for a period of time. Remember: if you can hear thunder, you’re close enough to be struck by lightning.
