...RIVER FLOOD OUTLOOK FOR PORTIONS OF DEEP SOUTH TEXAS...

HEAVY TO TORRENTIAL RAINFALL FORECAST OVER DEEP SOUTH TEXAS DURING 
THE NEXT 24 TO 48 HOURS WILL QUICKLY SATURATE SOILS CAUSING THE 
PONDING OF WATER ACROSS THE RIO GRANDE VALLEY. WIDESPREAD 
BASIN-AVERAGED RAINFALL AMOUNTS IN EXCESS OF 7.00 INCHES WITH 
LOCALIZED AMOUNTS OF 10.00 TO 15.00 INCHES MAY CAUSE RIVERS AND 
STREAMS TO RISE TO LEVELS THAT RESULT IN FLOODING.

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

- MINOR FLOODING ALONG THE RIO GRANDE FROM NEAR RIO GRANDE CITY   
  TO BROWNSVILLE. EQUIPMENT AND LIVESTOCK SHOULD BE MOVED FROM THE
  LOWEST AREAS OF THE FLOOD PLAIN. RIVER FLOODING WILL BE CONFINED
  WITHIN THE ENTIRE LEVEE SYSTEM.

- MINOR FLOODING ON THE LOS OLMOS CREEK NEAR FALFURRIAS.

- MINOR FLOODING ON THE LOS OLMOS CREEK NEAR RIO GRANDE CITY.

IN ADDITION, THERE IS A VERY SIGNIFICANT THREAT OF SEVERE INUNDATION
OF URBAN AND RURAL AREAS AWAY FROM THE RIO GRANDE, DUE TO THE 
TORRENTIAL RAINFALL THAT IS FORECAST TO OCCUR OVER THE NEXT 24 TO 
48 HOURS.

A RIVER FLOOD OUTLOOK MEANS THERE IS A POTENTIAL FOR RIVER
FLOODING...BUT IT IS NOT IMMINENT.  FORECAST RAINFALL MAY CAUSE 
RIVERS, ARROYOS 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.
