City Of West University Place issued the following announcement on June 22.
Isolated to scattered showers and thunderstorms will continue through the afternoon, but then a line of strong thunderstorms will develop this evening and slowly move through the area later this evening. There is a Flash Flood Watch in effect from 7pm this evening through 7am Wednesday morning.
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.
Primary Hazards:
Heavy rainfall
Strong damaging winds
Isolated tornadoes
Large Hail
