There is no safe place outside when thunderstorms are in the area. If you hear thunder, you are likely within striking distance of the storm. Just remember, When Thunder Roars, Go Indoors! Seek shelter in an enclosed building or hard-topped vehicle.

Isolated to scattered showers and thunderstorms are forecast for South Texas again today. It will be partly cloudy and warm with heat index values in the 100-110 degrees range.

There is a slight chance for showers and thunderstorms today across area beaches today with a LOW risk of rip currents. Remember, if you hear thunder, seek shelter immediately!

It will be mostly clear to partly cloudy tonight with lows in the 70s. Winds will be light out of the southeast.

The end of the week is shaping drier, but medium (30-50%) rain and thunderstorm chances return over the Holiday weekend. Expect warmer temperatures through Saturday, then slightly cooler Sunday and Monday owing to increased cloud coverage and rainfall potential.
