Heavy Rainfall Risk Through Weekend

Forecast Rainfall Totals

High Risk of Rip Currents

Current radar loop for Houston, TX.

Multiple rounds of showers and thunderstorms containing moderate to heavy rainfall expected through the weekend. Marginal Excessive Rainfall Risk (level 1 of 4) for most of Southeast Texas today into early Thursday. Slight Excessive Rainfall Risk (level 2 of 4) all of Southeast Texas on Thursday. Marginal Excessive Rainfall Risk (level 1 of 4) for all of Southeast on Friday. Slight Excessive Rainfall Risk (level 2 of 4) for all of Southeast Texas on Saturday due to potential additional shower/thunderstorm activity.

Unsettled pattern will lead to continued chances for showers and thunderstorms, with additional rounds of moderate to heavy rainfall. Periods of locally heavy rainfall are expected, through the weekend. Rainfall rates will peak in the 3-4+” per hour range in the heaviest downpours. This rainfall will generate runoff and river responses, especially where we see repeated heavy rainfall over the same locations leading to street flooding and river flooding potential through the weekend.

There is a high risk of rip currents along all Gulf facing beaches through Wednesday evening. Stay away from rocks and swim near a life guard.
