HURRICANE DORA DISCUSSION NUMBER 10
NWS NATIONAL HURRICANE CENTER MIAMI FL EP042011
200 PM PDT WED JUL 20 2011

DORA IS RAPIDLY STRENGTHENING. RECENT VISIBLE SATELLITE IMAGERY
SHOWS THAT AN EYE HAS FORMED WITH INTENSE CONVECTION IN THE EYEWALL
AND OCCASIONAL HINTS OF MESOVORTICES WITHIN THE EYE. DVORAK
ESTIMATES FROM TAFB AND SAB ARE 102 AND 90 KT RESPECTIVELY...WITH
THE OBJECTIVE NUMBERS FROM UW-CIMSS AT 115 KT. A BLEND OF THESE
DATA GIVES AN INITIAL WIND SPEED OF 100 KT...MAKING DORA THE SECOND
MAJOR HURRICANE OF THE 2011 EASTERN PACIFIC SEASON.

NOW THAT THE INNER CORE HAS SOLIDIFIED...DORA WILL PROBABLY
INTENSIFY AT A RAPID RATE FOR THE NEXT DAY OR SO DUE TO CONDUCIVE
ENVIRONMENTAL CONDITIONS. ALL OF THE RELIABLE GUIDANCE NOW SHOW
DORA PEAKING NEAR OR AT CATEGORY 4 STATUS TOMORROW. IN FACT THE
SHIP RAPID INTENSIFICATION INDEX INDICATES A 46 PERCENT CHANCE OF A
40 KT INCREASE WITHIN 24 HOURS...A RATHER HIGH VALUE. FROM THE 1800
UTC ESTIMATED INTENSITY OF 95 KT...THE NHC FORECAST WILL BE MORE
CONSERVATIVE BUT STILL INDICATE A 24-HOUR PERIOD OF RAPID
INTENSIFICATION. IN ABOUT TWO DAYS...SSTS FALL QUITE RAPIDLY...AND
SO SHOULD THE WINDS OF DORA. THE LATER PART OF THE NHC FORECAST IS
CLOSE TO A BLEND OF THE INTENSITY GUIDANCE...AND DORA SHOULD BECOME
POST-TROPICAL BETWEEN DAYS 4 AND 5.

THE HURRICANE HAS SLOWED A BIT AND IS MOVING 295/14. A TURN TOWARD
THE NORTHWEST AND A DECREASE IN FORWARD SPEED IS FORECAST OVER THE
NEXT COUPLE OF DAYS DUE TO THE WEAKENING OF A RIDGE OVER THE
CENTRAL UNITED STATES. MOST OF THE TRACK MODELS...SAVE THE
HWRF...KEEP DORA WELL OFFSHORE OF BAJA CALIFORNIA...AND ACTUALLY
TURN THE SYSTEM MORE TO THE WEST-NORTHWEST IN ABOUT THREE DAYS.
THE OVERALL TRACK ENVELOPE CONTINUES TO SHIFT WESTWARD IN THE
LONGER RANGE...AND THE NEW NHC FORECAST HAS BEEN MOVED IN THAT
DIRECTION.


FORECAST POSITIONS AND MAX WINDS

INIT 20/2100Z 15.5N 104.2W 100 KT 115 MPH
12H 21/0600Z 16.5N 105.8W 110 KT 125 MPH
24H 21/1800Z 17.7N 107.5W 125 KT 145 MPH

Official forecast is a conservative 125 kt and that kind of RI would make Dora a Cat 5 tomorrow...

Certainly possible, though at the moment I'd say a high end Cat-4 is probably a more likely peak. The key to watch for is if it develops a totally clear eye, if it does then a run at 5 is possible.

I think that 125 kt is a good forecast, I'm not sure if it can reach cat 5 but if it does I think it will be the first time in history that 3 consecutive seasons have had a cat 5.

Until Celia 10, we never even had 2 strait season of Cat 5, BTW. Ships RI says 46% chance.

With RI underway, the forecast is up to 145 mph. And they still give it ~10% chance of reaching Cat 5.

She needs to smooth out some of this raggedness though. That eye is squeezing all over the place right now

Well...I will say I'm not surprised...but the party is just beginning. My indicator popped up between 8 am EDT and 9 am EDT. Sadly, I've been at work all day and I missed it. Through 12:45 pm, the indicator was still there...so this little episode we are seeing now is nothing compared to what we are going to see this evening/overnight! (By the way, between 2 pm PDT yesterday and 2 pm PDT today, Dora increased 40 knots.)

I think thats my main reason why I think this one won't make it in terms of becoming a category-5...but to be fair its got enough time to sort it out...

Based on latest Dvorak numbers on CIMSS, I would put it at 110 kt at the intermediate advisory.
