  Galveston...Grimes...Harris...Liberty...Madison...Matagorda...
  Montgomery...San Jacinto...Walker...Waller...Washington and Wharton.

* From late tonight through Monday afternoon

* The combination of an approaching upper level storm system from
  the west and well above normal moisture levels will set the
  stage for widespread thunderstorm development with locally heavy
  rainfall. The flash flood threat will begin across western
  portions of southeast Texas during the early morning hours and
  will slowly progress eastward during the day. Rainfall amounts
  are expected to average between 1 to 3 inches across the watch
  area with localized areas expected to receive between 4 and 6
  inches of rainfall. These localized rainfall amounts when coupled
  with wet soils from previous rainfall would lead to flash flooding.

* Street flooding and flooding of low lying areas are the most
  likely impacts tonight and Monday. Small streams and bayous may
  be impacted during the day on Monday.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Flash Flood Watch means that conditions may develop that lead
