...FLASH FLOOD WATCH REMAINS IN EFFECT THROUGH SUNDAY EVENING...

THE FLASH FLOOD WATCH CONTINUES FOR

* PORTIONS OF SOUTHEAST TEXAS...INCLUDING THE FOLLOWING
  COUNTIES...JACKSON...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

* A SERIES OF UPPER LEVEL DISTURBANCES WILL PUSH THROUGH THE AREA
  TRIGGERING PERIODS OF RAIN WITH EMBEDDED STORMS. AS GROUNDS
  BECOME MORE SATURATED...THE THREAT OF FLASH FLOODING WILL
  PROGRESSIVELY INCREASE WHERE TRAINING HEAVIER CELLS MOVE OVER
  THE SAME AREA. EXCESSIVE RAINFALL HAS OCCURRED ALONG THE COAST
  ON SATURDAY...AND THAT WILL BE THE HIGHEST RISK LOCATION THROUGH
  SUNDAY MORNING. AN ADDITIONAL 2 TO 4 INCHES...WITH LOCALLY
  HIGHER AMOUNTS IN EXCESS OF 8 INCHES ARE POSSIBLE THROUGH
  MONDAY. WHERE GROUND IS ALREADY SATURATED IT IS MOST IMPORTANT
  TO FOCUS ON SHORT TERM RAINFALL RATES RATHER THAN TOTALS
  THEMSELVES. EVEN SHORT BURSTS OF HEAVY RAINFALL WILL QUICKLY
  CAUSE FLASH FLOODING AT THOSE LOCATIONS. TO FURTHER COMPLICATE
  THINGS...ELEVATED WATER LEVELS IN THE BAYS AND NEARSHORE GULF WILL
  DELAY DRAINAGE OF WATER.

* STREET FLOODING AND FLOODING OF LOW LYING AREAS WILL BE THE MOST
  LIKELY IMPACT TONIGHT. AS OF SATURDAY EVENING...AREA
  RIVERS...STREAMS AND BAYOUS WERE WITHIN BANKS. WE WILL CONTINUE
  TO MONITOR TRENDS.

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.
