... Flash Flood Watch in effect through Sunday evening...

The National Weather Service in Houston/Galveston has issued a

* Flash Flood Watch for portions of southeast Texas and
southeast Texas... including the following counties... in
southeast Texas... Jackson. In southeast Texas... 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

* heavy rainfall will be possible over the weekend and possibly
into Monday. Unusually moisture rich air for December flowing
into the region will interact with a stationary front near the
Upper Texas coast today and Sunday. A slow moving upper level
low pressure system moving into and then through the state will
provide abundant lift to the saturated airmass leading to
periods of rain mixed with bands or clusters of showers and
thunderstorms. The steady light rain should not pose a threat of
flooding but the bands that form may persist over the same areas
increasing the flood threat. These showers and thunderstorms
will be capable of heavy rainfall. Although the soil across the
region has been relatively dry two days of rainfall is likely
begin to saturate the soil. Heavy or intense rainfall will
likely lead to street flooding and flooding of low lying areas.
By Sunday the likelihood that small streams and bayous rise
will increase and these may eventually flood. Rainfall amounts
forecast across the region range from widespread 1 to 3 inches
with the possibility of bands of 5 to 7 inches with some
isolated places receiving 8 to 11 inches. The upper level low
pressure system moves through the region Monday and this should
sweep in dry air and end the threat of heavy rainfall by late
Monday afternoon.

* Street flooding and flooding of low lying areas will be the most
likely impacted today and tonight. Small streams and bayous may
becoming involved in flood on Sunday as well as additional
street flooding.

Precautionary/preparedness actions...

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.
