NATIONAL WEATHER SERVICE MIAMI FL
956 AM EDT WED SEP 21 2005

.UPDATE...NHC HAS UPGRADED HURRICANE RITA TO A CAT 4 HURRICANE AS
OF 8 AM THIS MORNING IN THE SOUTHEAST GULF OF MEXICO. HER FEEDER
BANDS WERE STILL AFFECTING THE WESTERN AREAS OF THE CWA...AND JUST
NORTHEAST OF PALM BEACH COUNTY EARLY THIS MORNING. THE OUTER
FEEDER BANDS SHOULD CONTINUE TO AFFECT SOUTH FLORIDA THIS
AFTERNOON...DUE TO THE SOUTHERLY WIND FLOW AROUND RITA BRINGING
IN DEEP TROPICAL MOISTURE TO THE AREA FROM THE CARIBBEAN SEA.
THEREFORE...PLAN ON LEAVING 50 PERCENT POPS IN THE EAST AND 60
PERCENT POPS IN THE WEST.

MIA SOUNDING THIS MORNING SHOWED THAT THE WINDS AROUND 900 MBS
WERE BETWEEN 25 TO 30 MPH. WITH RITA STRONGER THIS MORNING AND THE
HIGHER WINDS IN THE LOWER LEVELS OF THE ATMOSPHERE...PLAN RAISING
THE WINDS OVER THE CWA THIS AFTERNOON. FOR THE COASTAL
AREAS...PLAN ON HAVING THE WINDS 15 TO 20 MPH WITH GUSTS UP TO 25
MPH FOR THIS AFTERNOON AND THE INTERIOR AREAS 10 TO 15 MPH WITH
GUSTS UP TO 20 MPH.

FOR THE MARINE PACKAGE...THE CHANGES WILL BE TO INCREASE THE WINDS
TO 15 TO 20 KNOTS FOR THE ATLANTIC WATERS...BISCAYNE BAY...AND

THE SCEC GOING THROUGH THE AFTERNOON HOURS FOR THESE WATERS. NO
OTHER CHANGES ARE PLAN AT THIS TIME.

.PREV DISCUSSION...
..GRADUAL IMPROVEMENT TODAY OVER SOUTH FLORIDA AS RITA MOVES
FURTHER WEST...

DISCUSSION...
FOR TODAY AND TONIGHT...HURRICANE RITA CONTINUES TO MOVE AWAY FROM SOUTH
FLORIDA INTO THE GULF OF MEXICO. THE REMAINING RAINBANDS ARE
PASSING OVER MAINLY SOUTHWEST FLORIDA THIS MORNING. MOST OF THE
HEAVY RAINFALL WILL BE OFFSHORE IN THE GULF...ALTHOUGH ISOLATED
HEAVY SHOWERS WILL STILL MOVE NORTHWEST OFF THE ATLANTIC INTO
SOUTH FLORIDA. GPSMET PRECIPITABLE WATER VALUES FROM AROUND SOUTH
FLORIDA SHOW AROUND TWO INCHES...ABOUT NORMAL FOR THIS TIME OF
YEAR. SATELLITE IMAGERY IS SHOWING GENERALLY HIGH CLOUD OVER THE
BAHAMAS...AND EXPECT SOME BREAKS IN THE CLOUDS LATER TODAY OVER
SOUTH FLORIDA. AFTERNOON HEATING ALONG WITH REMAINING MOISTURE
WILL ALLOW FOR SCATTERED SHOWERS AND A FEW THUNDERSTORMS OVER
EASTERN AREAS TODAY. GUIDANCE IS SHOWING LIKELY POPS THROUGH
TONIGHT...BUT THIS IS PROBABLY DUE TO ANTICIPATION OF MORE
RAINBAND ACTIVITY ON THE EASTERN PERIPHERY OF THE STORM THAN WERE
SEEING. WILL KEEP LIKELY POPS FOR WESTERN AREAS THOUGH THE
MORNING TO COVER LINGERING RAINBANDS...THE LOWER THE POPS LATER IN
THE DAY. WILL ALLOW FLOOD WATCH TO EXPIRE AT 8 AM FOR THE SOUTHERN
TIP OF FLORIDA. WINDS HAVE DIMINISHED IN MOST AREAS TO 10 TO 15
KNOTS OUT OF THE SOUTHEAST...AND WILL CONTINUE TO SUBSIDE THROUGH
THE NIGHT.

FOR THE REST OF THE WORK WEEK AND INTO THE WEEKEND...RIDGE OF HIGH
PRESSURE WILL BUILD OVER THE WESTERN ATLANTIC. EAST FLOW WILL
FAVOR EAST COAST SEA BREEZE PENETRATION EACH AFTERNOON. GFS AND
NAM SHOW DEEP LAYER MOISTURE AMOUNTS WILL DECREASE BY LATE IN THE
WEEK. WILL MAINTAIN SCATTERED POPS OVER INTERIOR AND WEST COAST
AREAS BY THE WEEKEND...WITH ISOLATED POPS OVER THE EAST COAST.

MARINE...SCA CONDITIONS FOR OUTER GULF WATERS...AND GENERALLY
CAUTION CRITERIA ELSEWHERE TODAY. WINDS AND SEAS WILL DIMINISH
THROUGH TONIGHT.
