STORMS MAY DROP CIGS AND VISIBILITIES INTO IFR RANGE WITH HEAVY
RAINFALL AND HAVE THE POTENTIAL TO PRODUCE WIND GUSTS GREATER THAN
40 KTS.

&&

.HYDROLOGY...
HISTORIC RIVER FLOOD CONTINUES ACROSS MUCH OF THE CWA ON THE IOWA
SIDE OF THE MISSISSIPPI RIVER. MOST CRESTS HAVE BEEN ADJUSTED UPWARD
FROM YESTERDAY...AS WE GET A BETTER HANDLE ON THE SHEER AMOUNT OF
WATER COMING DOWN THESE RIVERS. THE MOST NOTABLE CHANGES WERE ON THE
DES MOINES RIVER...AND THOSE UPWARD ADJUSTMENTS WERE DUE TO CHANGES
IN PLANNED RELEASES FROM RED ROCK DAM UPSTREAM.

THE FORECAST RAINFALL SHOULD NOT ADD TO THE CRESTS EXPECTED ON THE
CEDAR AND IOWA RIVERS. ON THE MISSISSIPPI RIVER...HOWEVER...THE
FORECAST RAINFALL MAY INDEED ADD TO THE CREST ON THAT RIVER...
ESPECIALLY DOWNSTREAM OF THE QUAD CITIES WHERE THE MOST-SWOLLEN
RIVERS EMPTY INTO IT.  JAZ
