... Flash Flood Watch in effect through Tuesday morning... 

The National Weather Service in Houston/Galveston has expanded

* Flash Flood Watch to include a portion of southeast Texas...
including the following Brazoria... Chambers... Fort ... Bend...
Galveston... Harris... Jackson... Liberty... Matagorda...
Montgomery... Polk... San Jacinto... Trinity... Walker... Waller
and Wharton.

* Through Tuesday morning

* thunderstorms are expected to develop and move into the watch
area from central Texas. Some of these storms will be capable of
very heavy rainfall which may producing flash flooding. Some
storms may move over some of the same areas that received heavy
rainfall which will only prolong the threat for flash flooding.
The greatest threat for flash flooding appears to be from
College Station to Crockett tonight into Monday morning. Another
round of storms could affect the same area Monday night into
Tuesday. The threat for flooding may expand during this time to
include the Houston area and Gulf Coast. Three day rainfall
amounts from today through Tuesday are expected to be around 3
to 5 inches across the area with isolated amounts of greater
than 8 inches.

* Flooding impacts are expected to be flooding of low lying
roads and low water crossings. Expect rapid increases on area
rivers and creeks. Prolonged river flooding could result from
runoff of the excessive rainfall.

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.
