FLASH FLOOD WARNING
NATIONAL WEATHER SERVICE BROWNSVILLE TX
119 AM CDT FRI OCT 10 1997
 
THE NATIONAL WEATHER SERVICE IN BROWNSVILLE HAS ISSUED A
FLASH FLOOD WARNING EFFECTIVE UNTIL  315 AM CDT
FOR PEOPLE IN THE FOLLOWING LOCATIONS......
 
IN SOUTH TEXAS
 
   ...CENTRAL KENEDY COUNTY
 
BROWNSVILLE DOPPLER RADAR RAINFALL ESTIMATES INDICATE THAT IN EXCESS OF
FOUR AND A HALF INCHES OF RAIN HAS FALLEN OVER CENTRAL AND WEST CENTRAL
KENEDY COUNTY OVER THE PAST THREE HOURS. THE HEAVIEST RAINS HAVE
OCCURRED RIGHT ALONG HIGHWAY 77 AND JUST TO THE WEST OF THE HIGHWAY.
THIS AMOUNT OF RAIN ON TOP OF RECENT RAINS THAT SATURATED THE GROUND
IS ENOUGH TO CAUSE FLOODING OF LOW LYING AREAS AND COULD SEND CREEKS
OVER THEIR BANKS IN THE NORTHWEST PART OF THE COUNTY AS THE RAINS MOVE
UP THAT WAY.
 
 
 
A FLASH FLOOD WARNING MEANS THAT FLOODING IS OCCURRING OR IS
IMMINENT.  MOST FLASH FLOOD DEATHS OCCUR IN AUTOMOBILES.  DO NOT
ATTEMPT TO CROSS BRIDGES...DIPS...OR LOW SPOTS IF WATER COVERS
THE ROADWAY.  NEVER TRY TO CROSS A FLOWING STREAM...EVEN A SMALL
ONE...ON FOOT.  TO ESCAPE RISING WATER MOVE UP TO HIGHER GROUND.

Area forecast discussion, Oct 9, 7:52 PM CDT, 5 hours 27 minutes before
DEEP SOUTH TEXAS FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BROWNSVILLE TX
750 PM CDT THU OCT 9 1997

FOR THE MOMENT FORECAST HERE SEEMS IN ORDER..HIGH POP WITH MENTION
OF LOCALLY HEAVY. ANOTHER 2 TO 3 INCHES OVER THE SAME AREA IN CAMERON
AND WILLACY COUNTIES WHERE IT HIT DURING THE AFTERNOON WOULD MAKE
SIGNIFICANT FLOODING..BUT UNLESS RAIN BECOMES MORE WIDESPREAD..THREAT
WILL BE LOW. WILL LEAVE FOR MID MAN. BEFORE RADAR WENT KAPUT A FEW
MINS AGO..OVERLAND RAIN WAS INSIGNIFICANT. COASTAL FLOOD WATCH IS
VERY GOOD..WATER IS REACHING THE DUNES. SO IS SMALL CRAFT ADV.

UNTIL UPPER TROF DISTANT NORTHWEST STARTS TO MOVE..LOW OFFSHORE WILL
CONTINUE TO MOVE WWWRD AND MAKE EVEN MORE RAIN. PAULINE IS MAKING
CONTRIBUTION. QUESTION IN MY MIND IS HOW MUCH. HIGH LEVEL MOISTURE
IN ON THE WAY. SHOULD THERE BE SOME VORT AND LOWER LEVEL MOISTURE..
RAIN HERE COULD BE SUBSTANTIAL. PROGS INDICATE IT MAY ALL BLOW AWAY
BEHIND FRONT EARLY NEXT WEEK.
