FOR PEOPLE IN THE FOLLOWING LOCATION...

IN WEST TEXAS

   ...TERRELL COUNTY
 
A RAINFALL OBSERVER IN TERRELL COUNTY REPORTED OVER ONE INCH OF RAIN
HAD FALLEN BETWEEN 1PM AND 145PM. RADAR SHOWED VERY HEAVY
THUNDERSTORMS CONTINUING OVER TERRELL COUNTY AND AN ADDITIONAL ONE
TO TWO INCHES OF RAIN IS POSSIBLE... THIS IN COMBINATION TO ALREADY
SATURATED GROUNDS WILL LEAD TO POSSIBLE FLASH FLOODING ACROSS MUCH
OF TERRELL COUNTY.

THE STORMS WILL CONTINUE TO DRIFT SOUTH AT 10 MPH.

DO NOT DRIVE YOUR VEHICLE INTO AREAS WHERE THE WATER COVERS THE
ROADWAY. THE WATER DEPTH MAY BE TOO GREAT TO ALLOW YOUR CAR TO CROSS

PEOPLE IN  TERRELL COUNTY SHOULD MONITOR FLOOD CONDITIONS...AND BE
PREPARED TO MOVE TO HIGHER GROUND...SHOULD FLOODWATERS THREATEN.

What forecasters said that day

The local office's own words before this flash flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

Area forecast discussion, Aug 29, 9:17 AM CDT, 4 hours 34 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIDLAND TX
917 AM CDT THU AUG 29 1996

CURRENT FORECASTS LOOK ON TRACK... NO SUGGESTED CHANGES.

KMAF 12Z RAOB DATA CONTINUES TO SHOW COPIOUS AMOUNTS OF MOISTURE
OVER FA WITH PW/S AROUND 1.50 INCH.  MODIFYING SOUNDING SHOWS NO CAP
AND CAPES AROUND 1500 J/KG LATER THIS AFTERNOON.  SO BELIEVE AGAIN
MAIN THREAT WILL BE LOCALLY HEAVY RAINFALL.  ACCORDING TO LATEST WV
IMAGERY APPEARS A DRY SLOT IS MOVING DOWN FROM THE NORTH WITH SKIES
TRYING TO BREAK OUT BEHIND.  THIS MAY LEAD TO HIGHER TEMPS AND
GREATER CAPES ACROSS THE NORTHERN PORTIONS OF THE FA.  IF THIS
HAPPENS... SOME STORMS MAY APPROACH SEVERE.

MIGHT WOULD DROP TERRELL COUNTY POPS TO 50p PERCENT THOUGH AS LACKING
AREAL COVERAGE TO WARRANT 70 PERCENT.

OTHERWISE... FORECASTS COVER WEATHER SITUATION NICELY.

THUNDERSTORM OUTLOOK
NATIONAL WEATHER SERVICE MIDLAND TX
1052 AM CDT (952 AM MDT) THU AUG 29 1996

THIS OUTLOOK PERTAINS TO THE FOLLOWING COUNTIES IN WEST TEXAS:

ANDREWS   CULBERSON  GLASSCOCK   MARTIN    REAGAN   UPTON
BORDEN    DAWSON     HOWARD      MIDLAND   REEVES   WARD
BREWSTER  ECTOR      JEFF DAVIS  PECOS     SCURRY   WINKLER

AND IN SOUTHEAST NEW MEXICO:

EDDY      LEA

SYNOPSIS:  TROPICAL MOISTURE REMAINS OVER THE OUTLOOK AREA.  AS A
RESULT... THERE WILL BE A CHANCE OF THUNDERSTORMS THROUGH TONIGHT...
MOST NUMEROUS EAST OF A LINE FROM SEMINOLE... TO WINK... TO FORT
STOCKTON AND TO THE WEST OF SANDERSON.

NONE OF THESE STORMS ARE EXPECTED TO BECOME SEVERE.  HOWEVER... SOME
OF THE STRONGER STORMS WILL HAVE THE POTENTIAL OF PRODUCING VERY
HEAVY RAINFALL IN A SHORT PERIOD OF TIME.  THIS COMBINED WITH AN
ALREADY SATURATED GROUND WILL AID IN THE POSSIBILITY OF LOCALIZED
FLOODING.

SPOTTER ACTIVATION IS NOT ANTICIPATED.
