5-Day Outlook

As the cold front moves into the area and interacts with the available moisture around mid-week, heavy showers are looking more likely. Therefore, the Weather Prediction Center has issued a Slight Risk of excessive rainfall that could lead to flash flooding. Please have multiple ways to receive a warning.

Mostly sunny conditions will continue along beaches today with high temperatures in the upper 80s and a very high UV index. Southeast winds 5 to 10 mph. There's a low risk for rip currents today but low risk does not mean no risk. Dangerous rip currents are possible especially near piers and jetties.

Cloud cover will continue with balmy conditions overnight across South Texas. Low temperatures will range from the low 70s to around 80 along the coast.

Warm temperatures will continue through mid-week with rain chances beginning Tuesday. Our focus remains with a cold front and the possibility of heavy rain. As rain chances increase for the middle to late this week, heavy rain with the risk for flash flooding is also increasing.
