AT 421 AM CDT...FLASH FLOODING CONTINUES ACROSS THE WARNED AREA.

LOCATIONS IN THE WARNING INCLUDE BUT ARE NOT LIMITED TO WOODWARD...
STORY CITY...POLK CITY...NEVADA...MADRID...HUXLEY...ANKENY AND AMES

FLASH FLOODING CONTINUES TO CREATE A HAZARDOUS SITUATION ACROSS THE 
DES MOINES METRO AREA...WITH NUMEROUS REPORTS OF STREET FLOODING AND 
CARS STALLED IN ROADWAYS. SOME OF THE WATERS HAVE STARTED TO 
RECEDE...BUT FLOODING REMAINS A CONCERN ACROSS THE AREA.

WITH NEARLY 3 TO THREE AND ONE HALF INCHES OF RAIN HAVING FALLEN
ACROSS THE AMES AND DES MOINES METRO AREA...WITH LOCALLY HIGHER 
AMOUNTS POSSIBLY RECEIVED ACROSS THE WARNED AREA. ALTHOUGH THE 
RAINFALL HAS ENDED...THE RUNOFF FROM THE HEAVY RAINFALL WILL 
CONTINUE TO CREATE A DANGEROUS FLASH FLOODING SITUATION THROUGHOUT 
THE WARNED AREA. 

FLOODING CONTINUES ALONG WALNUT CREEK AT 63RD...WITH A CREST OF 17 
FEET EXPECTED LATER TODAY. FLOODING ALSO CONTINUES ALONG FOUR MILE 
CREEK AT EASTON BOULEVARD. 

EXCESSIVE RUNOFF FROM HEAVY RAINFALL WILL CAUSE FLOODING OF SMALL
CREEKS AND STREAMS...URBAN AREAS...HIGHWAYS...STREETS AND UNDERPASSES
AS WELL AS OTHER DRAINAGE AREAS AND LOW LYING SPOTS...AND FLOODING 
OF SMALL CREEKS AND STREAMS...COUNTRY ROADS...AS WELL AS FARMLAND 
ALONG THE BANKS OF CREEKS AND STREAMS.

BE ESPECIALLY CAUTIOUS AT NIGHT WHEN IT IS HARDER TO RECOGNIZE THE
DANGERS OF FLOODING. IF FLASH FLOODING IS OBSERVED ACT QUICKLY. MOVE
UP TO HIGHER GROUND TO ESCAPE FLOOD WATERS. DO NOT STAY IN AREAS
SUBJECT TO FLOODING WHEN WATER BEGINS RISING.

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. MOVE TO HIGHER GROUND.
