... Flash Flood Watch remains in effect through Sunday evening...
The Flash Flood Watch continues for
* portions of southeast Texas... including the following
counties... Jackson... Austin... Brazoria... Brazos... Burleson...
Chambers... Colorado... Fort Bend... Galveston... Grimes...
Harris... Houston... Liberty... Madison... Matagorda...
Montgomery... Polk... San Jacinto... Trinity... Walker... Waller...
Washington and Wharton.
* Through Sunday evening
* a series of upper level disturbances will push through the area
triggering periods of rain with embedded storms. As grounds
become more saturated... the threat of flash flooding will
progressively increase where training heavier cells move over
the same area. Excessive rainfall has occurred along the coast
on Saturday... and that will be the highest risk location through
Sunday morning. An additional 2 to 4 inches... with locally
higher amounts in excess of 8 inches are possible through
Monday. Where ground is already saturated it is most important
to focus on short term rainfall rates rather than totals
themselves. Even short bursts of heavy rainfall will quickly
cause flash flooding at those locations. To further complicate
things... elevated water levels in the bays and nearshore Gulf will
delay drainage of water.
* Street flooding and flooding of low lying areas will be the most
likely impact tonight. As of Saturday evening... area
rivers... streams and bayous were within banks. We will continue
to monitor trends.
A Flash Flood Watch means that conditions may develop that lead
to flash flooding. Flash flooding is a very dangerous situation.
You should monitor later forecasts and be prepared to take action
should flash flood warnings be issued.
