... Flash Flood Watch in effect from this evening through Monday
The National Weather Service in Houston/Galveston has issued a
* Flash Flood Watch for a portion of southeast Texas... including
the following counties... Austin... Brazoria... Brazos...
Burleson... Chambers... Colorado... Fort Bend... Galveston...
Grimes... Harris... Houston... Jackson... Liberty... Madison...
Matagorda... Montgomery... Polk... San Jacinto... Trinity...
Walker... Waller... Washington and Wharton.
* From this evening through Monday evening
* a slow moving upper level low pressure complex will tap into
Pacific moisture and Gulf moisture to bring heavy rainfall to
the region. Two systems are expected to slowly move through the
region. The first should arrive in the western portions of the
area tonight then shift eastward Sunday. The second is expected
Monday and continue into the late evening hours Monday. These
storms may hit the same areas and will be capable of intense
rain rates. Widespread accumulations of 2 to 4 inches is
expected across all of southeast Texas Sunday and Monday.
Isolated totals of 8 to 11 inches are likely.
* Impacts... with the ground across the area saturated and the
larger river swollen from the heavy rains of the last few weeks
the threat of flash flooding is high as is the threat of
mainstem river flooding. The intense rain rates and the
likelihood of storms moving over the same areas in quick
succession will produce street flooding. Over time the river may
climb out of banks with mainstem river flooding and significant
major flooding is a possibility.
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.
