A flash flood watch will be in effect for the entire region from 1:00 pm today (Thursday, May 9) to 7:00 pm tomorrow (Friday, May 10). Rainfall amounts are expected to be from 5 to 8 inches widespread. Significant street flooding is possible in areas of high hourly rainfall rates.
The Harris County Flood Control District (HCFCD) is continuing to monitor rainfall trends, which is expected to fall in clusters of intense bursts averaging 5-8 inches across the county through Saturday. With grounds saturated, additional heavy rainfall will likely result in increasing run-off and rapid rise on area creeks and bayous potentially to levels that could result in flooding. Additionally, there is also a risk of damaging hail and strong winds with isolated tornadoes possible.
