TROPICAL STORM WILMA DISCUSSION NUMBER 10
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
11 PM EDT MON OCT 17 2005
THE LAST RECON FIX AT 2130Z MEASURED A CENTRAL PRESSURE OF 989 MB...
AND THE ONBOARD RADAR REVEALED A DEVELOPING SMALL RAGGED EYE
FEATURE. A SERIES OF PASSIVE MICROWAVE OVERPASSES BY SSMI AND SSMIS
DURING THE PAST THREE HOURS ALSO INDICATES AT LEAST A MID-LEVEL
EYE-LIKE FEATURE. DEEP CONVECTION HAS BEEN PULSATING THIS EVENING
OVER THE ESTIMATED CENTER LOCATION... BUT WITHOUT ENOUGH
CONSISTENCY TO SUGGEST THAT THE STORM IS INTENSIFYING RAPIDLY. A
DISJOINTED AND BROAD BAND OF COLD CLOUD TOPS REMAINS WELL REMOVED
FROM THE CENTER IN THE SOUTHERN SEMICIRCLE... BUT THERE IS NO DATA
TO INDICATE TROPICAL STORM FORCE WINDS ARE OCCURRING THAT FAR FROM
THE CENTER. DVORAK INTENSITY ESTIMATES AT 00Z HAVE COME UP A BIT
TO 65 KT FROM TAFB AND 55 KT FROM SAB AND AFWA. GIVEN THESE
ESTIMATES AND THE STRUCTURE DEPICTED IN THE MICROWAVE IMAGERY...
THE ADVISORY INTENSITY IS INCREASED TO 55 KT. THIS REMAINS AT THE
LOWER END OF THE RANGE OF DVORAK ESTIMATES DUE TO THE PREVIOUSLY
DISCUSSED LAG BETWEEN THE SATELLITE SIGNATURE AND SURFACE WINDS
INDICATED BY THE EARLIER AIRCRAFT DATA. ANOTHER AIRCRAFT IS
SCHEDULED TO FLY INTO WILMA WITHIN THE NEXT FEW HOURS TO HELP GET A
BETTER HANDLE ON THE INTENSITY.
WILMA STOPPED LOSING LATITUDE EARLIER THIS EVENING WHEN IT PULLED UP
NEARLY STATIONARY... BUT THE RECENT MICROWAVE IMAGERY SUGGESTS IT
HAS BEGUN A WESTWARD DRIFT... AND THE ESTIMATED INITIAL MOTION
IS 270/2. OVERALL THE MODEL GUIDANCE ENVELOPE HAS SHIFTED A BIT TO
THE RIGHT OR EAST OF THE PREVIOUS ADVISORY... AND THE NEW OFFICIAL
FORECAST IS ADJUSTED IN THAT SAME DIRECTION THROUGHOUT THE FIVE DAY
PERIOD. THE MODELS GENERALLY AGREE THAT WILMA WILL RECURVE AFTER
ABOUT 72 HOURS THROUGH A WEAKNESS IN THE SUBTROPICAL RIDGE
ASSOCIATED WITH A MID-LATITUDE TROUGH PROGRESSING ACROSS THE
CONTINENTAL UNITED STATES. AS IS OFTEN THE CASE... HOWEVER... THE
MODELS GREATLY DISAGREE ON HOW SHARPLY WILMA WILL TURN AND HOW FAST
IT WILL MOVE AFTER RECURVATURE. MOST OF THE MODELS ARE NOW MUCH
FASTER AFTER RECURVATURE... BUT THE NEW OFFICIAL FORECAST WILL ONLY
BE ADJUSTED PART OF THE WAY BETWEEN THE PREVIOUS ADVISORY AND THE
LATEST DYNAMICAL MODEL CONSENSUS. CONDITIONS APPEAR CONDUCIVE FOR
STEADY STRENGTHENING WHILE WILMA REMAINS IN THE NORTHWESTERN
CARIBBEAN SEA... AND IT STILL APPEARS PROBABLE THAT WILMA WILL
BECOME A MAJOR HURRICANE. THEREAFTER... INCREASING SHEAR SHOULD
HALT INTENSIFICATION AND BEGIN TO INDUCE GRADUAL WEAKENING... BUT
NOT ENOUGH TO WEAKEN WILMA BENEATH HURRICANE INTENSITY WITHIN THE
FIVE-DAY TIME FRAME.

Tropical Storm Wilma Discussion Number 11
Statement as of 5:00 am EDT on October 18, 2005
there are several indicators suggesting that Wilma is strengthening.
The pressure has fallen to 982 mb. The cloud pattern consists of
very deep convection near the center with banding features...and
the outflow has continued to become more symmetrical. T-numbers
from TAFB and SAB are 4.0 on the Dvorak scale...suggesting that
Wilma is a hurricane. In addition...two microwave passages from
different satellites show an eye feature. However...wind
observations from the Air Force plane do not support winds higher
than 60 knots at this time. Given the conditions of light shear and
very warm ocean...strenghtening is indicated. The official
intensity forecast is between the GFDL and the SHIPS models. Wilma
is expected to become an intense hurricane in the northwestern
caribean sea...typical of those hurricanes which commonly occurred
in October during the 30's 40's and 50's. This is nothing new.
Wilma has barely moved for the past several hours. Despite models
showing a weakening of the anticylone over the Gulf of Mexico...
this feature is still there and strong...blocking the motion of
Wilma. It is still fresh in my memory that...in 1998 with a similar
steering pattern...all models moved hurricane Mitch northward and
the hurricane indeed moved southward. However...dynamical models
have improved a lot since then and the confidence is higher. The
anticyclone in the Gulf is forecast to weaken as a large trough
sweeps eastward across the United States...and the Atlantic
subtropical ridge is also forecast to build. This should result in
a slow west to northwest motion of Wilma during the next 2 to 3
days...toward the extreme northwestern Caribbean Sea. Thereafter...
Wilma will be approaching the westerlies and recurvature with an
increase in forward speed is forecast. This is consistent with the
guidance envelope which shows a hurricane moving either over the
Yucatan Channel or western Cuba and then over the southern half of
the Florida penisula between days 4 and 5. Remember...there is a
large variability and large errors associated with the 4 and 5 day
forecasts. So at this time stay tune and monitor closely the
progress of this hurricane.

Notice at the end of the discussion he said "we need to watch the progress of this hurricane". I think he meant "we need to watch the progress of this soon to be hurricane" It's 70mph at this advisory.

I noticed Avila in the 5 AM said "It is fresh in my memory that... in 1998 with a similar steering pattern...all models moved hurricane Mitch northward and the hurricane indeed moved southward. However...dynamic models have improved a lot since...."
If anyone wants to go back in time and 'experience' the events surrounding that storm, pick up the book " The Ship and the Storm: Hurricane Mitch and the Loss of the Fantome" by Jim Carrier. Its made to order for Storm2k'ers. The author had unprecedented access to the NHC and the book is exceptionally well written.

Does anyone see one a second outflow channel might develop? Right now there seems just to be that one very pronounced poleward one that runs from Wilma through the Bahamas.
Outflow is still constricted to the northwest, once that area fills in, we could be in for a very powerful storm indeed.

I think everyone should relax on this now. I just explained to my son everything I know about Wilma including the models and how everything is setting up. I am a bit concerned being in PB County that we could easily get Cat 1 winds if it tracks this way. Well my 2 year old just eased my tension when he told me to not be scared b/c Wilma is a nice girl! Thank God.
