NWS Houston/Galveston Flash Flood Watch (02/23/2020)

From the NW Houston/Galveston:

There will be isolated to scattered showers and thunderstorms through the afternoon today mainly south of I-10 that may produce isolated spots of 1 to 2 inches. However, the main concern will be from a line of storm thunderstorms that will develop over the northwestern portion of the region this evening and slowly move eastward through tomorrow morning. Widespread rainfall through Wednesday morning will average between 2 and 4 inches with isolated high end amounts between 6 and 8 inches possible. The WPC has placed much of SE TX in a Slight Risk for excessive rainfall later today and tonight, and we have issued a Flash Flood Watch from 7pm this evening through 7am Wednesday morning. In addition to the heavy rain threat, the SPC has placed portions of the area in a Slight Risk for severe thunderstorms this evening and tonight with hail and strong winds possible. Confidence is high that rain will develop, but confidence in timing and location remains moderate to low since much of the activity will be driven by small scale features.

The biggest threat of this storm system will be heavy, possibly intense, rainfall that could create street flooding. This is especially a concern due to the storms pushing through at night when visibility is at its lowest. Depending on the actual rainfall received, we could see some rapid rises on our creeks and streams; however, the NWS does not anticipate our major creeks and streams exceeding their banks.

For more information on this system, SpaceCityWeather put out an update at 1:19 PM.

Similarly, we do not anticipate a major rise on the Brazos River; however, like we saw on Monday we could see a minor jump in the elevations through Fort Bend County.

We encourage everyone to follow good flood safety standards and stay informed through trusted sources such as the National Weather ServiceWest Gulf River Forecast Center, and the Fort Bend County Office of Homeland Security & Emergency Management.
