...FLASH FLOOD WATCH REMAINS IN EFFECT UNTIL 4 PM CDT THIS
AFTERNOON...

The Flash Flood Watch continues for

* Portions of Southeast Texas and southeast Texas...including
  the following counties...in Southeast Texas...Jackson. In
  southeast Texas...Austin...Brazoria...Chambers...Colorado...
  Fort Bend...Galveston...Harris...Liberty...Matagorda...Waller
  and Wharton.

* Until 4 PM CDT this afternoon

* Showers and thunderstorms are expected to persist through much
  of the day today. Upper level disturbances and favorable winds
  aloft in this warm moist and unstable airmass will aid in storm
  development this afternoon. Rainfall amounts of 1 to 3 inches
  will be possible in the watch area with the potential for higher
  isolated amounts of 4 to 6 inches. These higher rainfall
  amounts could lead to flash flooding.

* Areas that saw heavy rainfall earlier this morning (especially
  Brazoria and Galveston counties) will be particularly sensitive
  to any additional rainfall received during the day. Around 8 to
  10 inches of rain fell across parts of these counties overnight.

* Flash flooding will be possible from any storms that produce
  heavy rainfall. This includes water rapidly rising in roads
  with poor drainage, rising waters on area creeks, bayous and
  rivers due to runoff. Flood waters could damage bridges over
  streams impeding travel. Flooding could impact homes in low
  lying areas. Flooding will likely be at night in which
  visibility will be restricted. Do not drive into any water at
  night.

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.
