FLOOD WATCH [EXAMPLE]
NATIONAL WEATHER SERVICE SHREVEPORT LA
1025 AM CST FRI MAR 30 2001

...RIVER FLOOD WATCH IN EFFECT FOR PORTIONS OF SOUTHEAST OKLAHOMA
AND SOUTHWEST ARKANSAS...

THE NATIONAL WEATHER SERVICE IN SHREVEPORT AND THE ARKANSAS RED
BASIN RIVER FORECAST CENTER IN TULSA OKLAHOMA HAVE ISSUED A RIVER
FLOOD WATCH FOR PORTIONS OF SOUTHEAST OKLAHOMA AND SOUTHWEST
ARKANSAS EFFECTIVE UNTIL 10 PM SATURDAY.

HEAVY RAINFALL THAT IS FORECAST OVER SOUTHEAST OKLAHOMA AND
SOUTHWEST ARKANSAS DURING THE NEXT 24 HOURS WILL QUICKLY RUN OFF
ALREADY SATURATED SOILS.  WIDESPREAD BASIN-AVERAGED RAINFALL
AMOUNTS IN EXCESS OF ONE INCH WITH LOCALIZED AMOUNTS OF 2 TO 3
INCHES MAY CAUSE RIVERS AND STREAMS TO RISE TO LEVELS THAT RESULT
IN FLOODING.

THIS RIVER FLOOD WATCH IS IN EFFECT DUE TO THE POTENTIAL FOR...

- MODERATE FLOODING ON THE GLOVER RIVER NEAR GLOVER
- MINOR FLOODING ALONG THE LITTLE RIVER FROM NEAR IDABEL TO
  NEAR HORATIO
- MINOR FLOODING ON THE RED RIVER NEAR FULTON

A RIVER FLOOD WATCH MEANS RIVER FLOODING IS POSSIBLE...BUT NOT
IMMINENT. FORECAST RAINFALL MAY CAUSE RIVERS AND STREAMS TO RISE
TO CRITICAL STAGES.  PERSONS WITH INTERESTS ALONG THE AREAS
MENTIONED ABOVE SHOULD REMAIN INFORMED OF THE LATEST WEATHER AND
RIVER INFORMATION AND BE PREPARED TO TAKE ACTION AS NECESSARY.
PLEASE REFER TO NATIONAL WEATHER SERVICE RIVER FLOOD WARNINGS AND
STATEMENTS FOR THE LATEST INFORMATION IN YOUR AREA.

THIS IS NOT A FLASH FLOOD WATCH.  FLASH FLOOD WATCHES ARE ISSUED
SEPARATELY FOR SHORTER TIME PERIODS AND SMALLER STREAMS...OR
URBAN AREAS...FOR IMMEDIATE PUBLIC ATTENTION.

A GRAPHIC SHOWING THE COUNTIES...RIVER FORECAST POINT
LOCATIONS...AND RIVER REACHES IN THE WATCH AREA IS AVAILABLE AT
THE FOLLOWING WEB SITE /USE LOWER CASE/::

     HTTP://WWW.SRH.NOAA.GOV/ABRFC/RFW/SHVRFW.HTML

END OF PRODUCT
END OF EXAMPLE


A RIVER FLOOD WATCH IS DIFFERENT THAN A FLASH FLOOD WATCH.  A
FLASH FLOOD WATCH IS ISSUED FOR SMALL STREAMS OR URBAN AREAS THAT
MIGHT ENCOUNTER FLASH FLOODING WITHIN SIX HOURS OF THE CAUSATIVE
EVENT /E.G. HEAVY RAINFALL...DAM FALURE/.  A RIVER FLOOD WATCH IS
ISSUED FOR LARGER MAINSTEM RIVERS AND TRIBUTARIES THAT MIGHT
FLOOD WITHIN 48 HOURS BASED ON FORECAST RAINFALL USED IN FLOOD
PREDICTION MODELS.

TO REPEAT...THE NWS OFFICES AND RIVER FORECAST CENTERS IN THE
SOUTHERN REGION WILL BEGIN ISSUANCE OF A NEW RIVER FLOOD WATCH
PRODUCT BEGINNING WEDNESDAY... SEPTEMBER 5 2001.
