FLOOD WARNING EFFECTIVE UNTIL 100 AM CDT
FOR PEOPLE IN THE FOLLOWING LOCATIONS......

IN SOUTH TEXAS

   ...CAMERON COUNTY...WILLACY COUNTY...

...THE FLOOD WARNING FOR CAMERON COUNTY IS BEING EXTENDED THROUGH
   1 AM SUNDAY MORNING AND HAS BEEN EXPANDED TO INCLUDE WILLACY
   COUNTY...

MANY STREETS AND ROADWAYS AROUND CAMERON COUNTY...ESPECIALLY IN THE
BROWNSVILLE AREA...REMAIN UNDER WATER.  HEAVY RAINFALL TOTALS OVER
9 INCHES ON FRIDAY AND ADDITIONAL RAINS LATE LAST NIGHT HAVE CAUSED
PONDING OF WATER IN LOW LYING AREAS AROUND THE CITY OF BROWNSVILLE.
SOME ROADS ARE CLOSED WITH OTHERS NEARLY IMPASSABLE. WATER IS
ESTIMATED AS HIGH AS 2 TO 3 FEET ON SOME STREETS AND INTERSECTIONS.
BOCA CHICA BLVD. REMAINS CLOSED IN SEVERAL AREAS BETWEEN HIGHWAY 77
AND THE BROWNSVILLE AIRPORT.  IN ADDITION...MUCH OF THE BROWNSVILLE
AIRPORT REMAINS FLOODED. 

CURRENTLY...BROWNSVILLE DOPPLER RADAR INDICATED AREAS OF MODERATE
RAIN FALLING ACROSS CAMERON AND WILLACY COUNTIES...WITH MORE
WIDESPREAD AREAS OF HEAVIER RAINFALL OCCURING OVER THE MEXICAN AND
TEXAS GULF WATERS. THIS RAIN ACTIVITY IS ASSOCIATED WITH THE
NORTHERN EDGES OF TROPICAL DEPRESSION # TEN LOCATED ABOUT 200 SOUTH
SOUTHEAST OF BROWNSVILLE.
   
SINCE TROPICAL DEPRESSION TEN IS EXPECTED TO REMAIN NEARLY
STATIONARY FOR THE NEXT 24 HOURS...ADDITIONAL PERIODS OF HEAVY RAIN
ARE LIKELY THIS EVENING AND TONIGHT...ESPECIALLY NEAR THE DEEP SOUTH
TEXAS COASTLINE.  THE ANTICIPATED RAINFALL THIS EVENING AND TONIGHT
WILL LIKELY ADD TO THE CURRENT FLOODING IN CAMERON COUNTY AND WILL
INCREASE THE FLOODING POTENTIAL IN WILLACY COUNTY.  RAYMONDVILLE
POLICE CURRENT REPORT THAT SEVERAL STREAMS ARE NEAR BANKFUL AND
WILL LIKELY FLOOD THIS EVENING DUE TO ADDITIONAL RAINFALL.

IN ADDITION...A COASTAL FLOOD WARNING REMAINS IN EFFECT FROM PORT
OCONNER TO BROWNSVILLE TODAY.  SMALL CRAFT ARE ADVISED TO REMAIN IN
PORT.

ALSO...A FLASH FLOOD WATCH ALSO REMAINS IN EFFECT FOR CAMERON...
WILLACY...HIDALGO AND KENEDY COUNTIES. 

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 SAFELY. VEHICLES CAUGHT IN RISING WATER SHOULD BE
ABANDONED QUICKLY.  

PERSONS LOCATED IN THE WATCH AND WARNING AREAS SHOULD STAY TUNED TO
NOAA WEATHER RADIO OR YOUR LOCAL COMMERCIAL TV OR RADIO STATIONS FOR
ADDITIONAL STATEMENTS AND POSSIBLE WARNINGS CONCERNING THIS WEATHER
SITUATION.

DEEP SOUTH TEXAS FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BROWNSVILLE TX
250 PM CDT SAT OCT 5 1996

SHORT TERM...CURRENT KBRO REFLECTIVITY SHOWS LARGE AREA OF >30 DBZ
REFLECTIVITY JUST OFFSHORE AND ALONG DEEP SOUTH TX COASTLINE WITH
WEAKER CONV OVER TXZ251-254-255.  CURRENT RADAR LOOPS SHOW THAT
AREAL COVERAGE OF ACTIVITY IS EDGING WESTWARD WITH CELLULAR
MOVEMENT TO THE SOUTHWEST AT 10 TO 15 MPH NEAR SHORE.  LOOPING ALSO
INDICATES THAT SOME KIND OF CYCLONIC MOTION OF THE CONV BANDS.
HOWEVER...WOULD LIKE TO HEAR FROM THE NEXT RECON PLANE BEFORE
JUMPING TO CONCLUSIONS.  SATL IMAGERY (AS PER SPENES DISC) SHOWS
MUCH COLDER CLD TOPS ACCOMPANING THAT CONV WITH EST RAINFALL RATES
UP TO 2 IN/HR.  THE SPENES ALSO INDICATE THAT WIDESPREAD HIGH PWAT
VALUES REMAIN ENTRENCHED OVER THE FA AND THE GULF.   SO WILL LEAVE
GOING FORECAST AS IS FOR TONIGHT AND WILL INCLUDE WILLACY COUNTY
(TXZ254) IN THE FLOOD WARNING AS SOME HEAVIER CONV BANDS ARE
ALREADY MAKING THEIR WAY INTO THE COUNTY.  WILL ALSO MAKE SOME
MINOR ADJUSTMENTS TO GOING POPS.

AGREE WITH SAT DISC THAT SYSTEM SHOULD BECOME MORE BAROCLINIC AND
WILL BE SLOWLY DRAWN NORTHEAST FURTHER INTO THE GULF AFTER 12Z
MONDAY.  HOWEVER...UNTIL THIS DEVELOPS WILL MAINTAIN HIGH POPS FOR
THE FORECAST AREA FOR ALL 4 PDS.  94Q AND 98Q CONTINUES TO
ADVERTISE MORE OF A NORTHWARD SHIFT OF THE PCPN MAXES TOWARDS THE
COASTAL BEND AREA.

OTHERWISE...CONTINUE FLASH FLOOD WATCH AND COASTAL FLOOD WARNING.

LONG RANGE...AS THE ANTICIPATED "KICKER" PICKS UP T.D. TEN...POPS
SHOULD DROP CONSIDERABLY IN THE 3 TO 5 DAY RANGE.  HOWEVER...THE
LARGE FLY IN THE OINTMENT WILL BE HOW FAST THE SYSTEM LIFTS OUT.
COULD SEE SOME LINGERING POPS TUESDAY AND INTO WEDNESDAY WITH
PARTLY CLOUDY SKIES PREVAILING.  TEMP EXTREMES - 80S/60S INLAND -
70S AT THE COAST.
