HURRICANE WILMA ADVISORY NUMBER 23
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
10 PM CDT THU OCT 20 2005

...EXTREMELY DANGEROUS CATEGORY FOUR WILMA MOVING SLOWLY TOWARD COZUMEL AND BECOMING BETTER ORGANIZED...

A HURRICANE WARNING REMAINS IN EFFECT FROM SAN FELIPE TO CHETUMAL ON THE YUCATAN PENINSULA...INCLUDING COZUMEL AND THE NEARBY ISLANDS.

A TROPICAL STORM WARNING AND A HURRICANE WATCH REMAIN IN EFFECT FROM WEST OF SAN FELIPE TO CELESTUN.

A TROPICAL STORM WARNING REMAINS IN EFFECT FOR BELIZE FROM THE BORDER WITH MEXICO SOUTHWARD TO BELIZE CITY.

A TROPICAL STORM WARNING IS IN EFFECT FOR THE PROVINCES OF LA HABANA...CIUDAD DE LA HABANA...PINAR DEL RIO...AND THE ISLE OF YOUTH. A HURRICANE WATCH REMAINS IN EFFECT IN CUBA FOR THE PROVINCES OF MATANZAS WESTWARD THROUGH PINAR DEL RIO...AND FOR THE ISLE OF YOUTH.

AT 10 PM CDT...0300Z...THE GOVERNMENT OF HONDURAS HAS DISCONTINUED THE HURRICANE WARNING FOR SWAN ISLAND AND THE TROPICAL STORM WARNING FOR THE COAST OF HONDURAS.

ALL INTERESTS IN THE FLORIDA KEYS AND THE FLORIDA PENINSULA SHOULD CLOSELY MONITOR THE PROGRESS OF EXTREMELY DANGEROUS HURRICANE WILMA.

FOR STORM INFORMATION SPECIFIC TO YOUR AREA...INCLUDING POSSIBLE INLAND WATCHES AND WARNINGS...PLEASE MONITOR PRODUCTS ISSUED BY YOUR LOCAL WEATHER OFFICE.

AT 10 PM CDT...0300Z...THE CENTER OF HURRICANE WILMA WAS LOCATED NEAR LATITUDE 19.3 NORTH...LONGITUDE 86.0 WEST OR ABOUT 100 MILES... 165 KM...SOUTHEAST OF COZUMEL MEXICO.

WILMA IS MOVING TOWARD THE NORTHWEST NEAR 6 MPH... 9 KM/HR...AND A SLOW NORTHWESTWARD TO NORTH-NORTHWESTWARD MOTION IS EXPECTED TO CONTINUE FOR THE NEXT 24 HOURS. ON THE FORECAST TRACK...THE CENTER OF WILMA WILL BE VERY NEAR COZUMEL AND THE NORTHEASTERN COAST OF THE YUCATAN PENINSULA BY MIDDAY TOMORROW. HOWEVER...WILMA HAS A LARGE CIRCULATION AND HURRICANE CONDITIONS WILL BE FELT WELL BEFORE THE ARRIVAL OF THE CENTER.

MAXIMUM SUSTAINED WINDS ARE NEAR 150 MPH...240 KM/HR...WITH HIGHER GUSTS. WILMA IS A CATEGORY FOUR HURRICANE ON THE SAFFIR-SIMPSON SCALE. SATELLITE IMAGERY INDICATES THAT WILMA IS GRADUALLY BECOMING BETTER ORGANIZED...AND THE HURRICANE COULD REGAIN CATEGORY FIVE STRENGTH AS IT APPROACHES THE YUCATAN TONIGHT OR FRIDAY.

HURRICANE FORCE WINDS EXTEND OUTWARD UP TO 85 MILES...140 KM... FROM THE CENTER...AND TROPICAL STORM FORCE WINDS EXTEND OUTWARD UP TO 200 MILES...325 KM. NOAA BUOY 42056 RECENTLY REPORTED SUSTAINED WINDS OF 77 MPH... 124 KM/HR...WITH A GUST TO 87 MPH... 140 KM/HR.

ESTIMATED MINIMUM CENTRAL PRESSURE IS 923 MB...27.26 INCHES.

COASTAL STORM SURGE FLOODING OF 7-11 FEET ABOVE NORMAL TIDE LEVELS...ALONG WITH LARGE AND DANGEROUS BATTERING WAVES...CAN BE EXPECTED NEAR AND TO THE NORTH OF WHERE THE CENTER MAKES LANDFALL ON THE YUCATAN PENINSULA.

WILMA IS EXPECTED TO PRODUCE 10 TO 20 INCHES OF RAIN THROUGH SATURDAY ACROSS PORTIONS OF WESTERN CUBA AND THE YUCATAN PENINSULA...WITH ISOLATED AMOUNTS OF 40 INCHES POSSIBLE... PARTICULARLY OVER HIGHER TERRAIN OF WESTERN CUBA. OUTER RAINBANDS WILL CONTINUE TO AFFECT PORTIONS OF SOUTHERN FLORIDA...ESPECIALLY THE KEYS...WITH SOME 1 TO 3 INCH RAINS POSSIBLE THROUGH SATURDAY.

NOAA BUOY 42003 IN THE EASTERN GULF OF MEXICO INDICATES THAT LARGE SWELLS GENERATED BY WILMA HAVE PROPAGATED WELL INTO THE EASTERN GULF OF MEXICO. THESE SWELLS WILL LIKELY AFFECT PORTIONS OF THE NORTHERN GULF COAST ON FRIDAY.

REPEATING THE 10 PM CDT POSITION...19.3 N... 86.0 W. MOVEMENT TOWARD...NORTHWEST NEAR 6 MPH. MAXIMUM SUSTAINED WINDS...150 MPH. MINIMUM CENTRAL PRESSURE... 923 MB.

AN INTERMEDIATE ADVISORY WILL BE ISSUED BY THE NATIONAL HURRICANE CENTER AT 1 AM CDT FOLLOWED BY THE NEXT COMPLETE ADVISORY AT 4 AM CDT.

FORECASTER BEVEN

HURRICANE WILMA DISCUSSION NUMBER 23
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
11 PM EDT THU OCT 20 2005

REPORTS FROM A NOAA HURRICANE HUNTER AIRCRAFT BEFORE 00Z INDICATED
THAT THE CENTRAL PRESSURE OF WILMA HAD RISEN TO 923 MB...AND THE
MAXIMUM 700 MB FLIGHT-LEVEL WINDS HAD DECREASED TO 130-140 KT.
SINCE THEN...SATELLITE IMAGERY SHOWS AN IMPROVED EYE PRESENTATION
AND COOLING CLOUD TOPS AROUND THE CENTER..ALTHOUGH NOT ENOUGH TO
JUSTIFY AN INCREASE IN INTENSITY. BASED ON THIS...THE INITIAL
INTENSITY REMAINS 130 KT. THE NEXT AIRCRAFT WILL INVESTIGATE WILMA
AROUND 05Z.

WILMA HAS TURNED MORE TO THE RIGHT DURING THE PAST FEW HR...WITH THE
INITIAL MOTION NOW 325/5. THE HURRICANE IS MOVING INTO A COL AREA
BETWEEN MID-LEVEL RIDGES TO THE EAST AND WEST...WHILE THE STRONGER
WESTERLIES REMAIN NORTH OF 26N ACCORDING TO DATA FROM THE NOAA G4
JET. THIS IS A GOOD FORMULA FOR SLOW MOTION...AND ALL MODELS AGREE
ON THIS FOR THE NEXT 24-48 HR. HOWEVER...THE DYNAMICAL MODELS
STEER WILMA NORTHWESTWARD INTO THE YUCATAN PENINSULA DURING THE
NEXT 12-24 HR...A MOTION THAT IS NOT SUPPORTED BY THE CURRENT RIGHT
TURN OR THE JET DATA. THEREFORE...THE FORECAST TRACK WILL BE WELL
TO THE RIGHT OF THE MODEL GUIDANCE...WITH THE CENTER FORECAST TO
PASS OVER THE EXTREME NORTHEASTERN TIP OF THE YUCATAN PENINSULA.
THIS TRACK ALSO REQUIRES AN EARLIER RECURVATURE INTO THE WESTERLIES
THAN ANY OF THE GUIDANCE AND A FASTER PROGRESS TOWARD THE NORTHEAST
AND THE FLORIDA PENINSULA. THE NEW FORECAST TRACK IS SIMILAR TO
THE PREVIOUS FORECAST...EXCEPT SOMEWHAT SLOWER THROUGH 96 HR.
GIVEN THE RADICAL DEPARTURE FROM THE MODEL GUIDANCE...THIS IS A LOW
CONFIDENCE FORECAST.

THE INTENSITY FORECAST IS VERY PROBLEMATIC. FIRST...THE INTENSITY
FORECAST CALLS FOR WEAKENING DUE TO PASSAGE OVER THE YUCATAN
PENINSULA. IF WILMA MOVES AS FAR INLAND AS THE MODELS FORECAST...
IT WILL WEAKEN CONSIDERABLY AND LIKELY BE MUCH WEAKER THAN FORECAST
ALONG THE REST OF THE TRACK. ON THE OTHER HAND...IF THE EYE MOVES
EAST OF THE TRACK THE HURRICANE WILL LIKELY STAY STRONGER THAN
FORECAST...AT LEAST FOR THE FIRST 36-48 HR. SECOND...ALL AVAILABLE
DATA SHOWS THAT THE OUTFLOW HAS DECREASED TO THE WEST AS WEAK
WESTERLY FLOW IMPINGES ON WILMA. THIS WILL LIKELY NOT PREVENT THE
INTENSIFICATION FORECAST DURING THE NEXT 24 HR...ALTHOUGH IT MAY BE
A PRECURSOR TO THE SHEAR FORECAST TO AFFECT THE HURRICANE OVER THE
GULF OF MEXICO. THIS SHEAR SHOULD CAUSE WILMA TO WEAKEN REGARDLESS
OF HOW STRONG IT IS AFTER PASSING YUCATAN. THIRD...WATER VAPOR
IMAGERY CONTINUES TO SHOW VERY DRY MID/UPPER-LEVEL AIR COVERING THE
GULF OF MEXICO. AS WILMA INTERACTS WITH THE WESTERLIES...THIS AIR
SHOULD BEGIN TO ENTRAIN INTO THE HURRICANE...AND INDEED THERE HAS
BEEN SOME EROSION OF THE WESTERN SIDE OF THE CLOUD PATTERN DURING
THE PAST 6 HR. FINALLY...WILMA SHOULD PASS OVER THE WARM LOOP
CURRENT FOLLOWED BY COOLER WATERS NEAR THE FLORIDA PENINSULA. THE
LATTER SHOULD AID THE SHEAR-INDUCED WEAKENING. GIVEN THE
UNCERTAINTIES...THE INTENSITY FORECAST WILL CHANGE LITTLE FROM THE
PREVIOUS ADVISORY. IT SHOULD BE NOTED THAT IF WILMA MISSES YUCATAN
THERE IS A CHANCE THAT IN SPITE OF ALL THE NEGATIVE FACTORS IT
COULD BE A MAJOR HURRICANE AT LANDFALL IN FLORIDA.

NOAA BUOY 42003 IN THE EASTERN GULF OF MEXICO REPORTS THAT LARGE
SWELLS GENERATED BY WILMA ARE PROPAGATING TOWARD PORTIONS OF THE
NORTHERN GULF COAST...AND COULD REACH THE COAST ON FRIDAY.
