Yeah that's true, but did Karen have anything to do with 93?

Looks like a 40-45 knot tropical storm with the burst of convection forming near the core if not slightly displaced northeastward.

Brown=35 knots colar on rain flag far away from the center(about 90-120 miles). I hope that is not a rainflaged one. But any ways even if its not, it likely has 35 knot winds near the core.

Interesting paragraph about what NHC thinks about the dead Karen playing a roll with this.


Karen Died 13 days ago. I doubt it.

We don't have the data for the upgrade. Hopefully a clear quickscat go's over soon, but any ways I do believe ita borderline right now. In could easly go over to tropical storm, but hey we all got options.

I strongly believe now it has reached tropical storm strength. The LLC has became very well defined and convection is firing over it. Classic sheared tropical storm.

TROPICAL DEPRESSION FIFTEEN DISCUSSION NUMBER 2
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL AL152007
1100 PM EDT THU OCT 11 2007

THE OVERALL CLOUD PATTERN OF THE DEPRESSION HAS CHANGED VERY LITTLE
THIS EVENING. DVORAK INTENSITY ESTIMATES FROM SAB AND TAFB ARE 25
AND 30 KT RESPECTIVELY AND THE INITIAL INTENSITY WILL REMAIN 30 KT.
THE DEPRESSION IS ONCE AGAIN IN THE QUIKSCAT GAP...BUT AMSU AND SSMI
MICROWAVE OVERPASSES HAVE BEEN HELPFUL IN FINDING THE CENTER OF THE
CYCLONE...WHICH IS LOCATED JUST SOUTHWEST OF THE DEEP CONVECTION.
BASED ON THE MICROWAVE AND SATELLITE FIXES...THE DEPRESSION HAS
BEEN DECELERATING DURING THE PAST FEW HOURS AND THE INITIAL MOTION
ESTIMATE IS 090/8 KT.

AN UPPER LEVEL TROUGH SEEN IN WATER VAPOR IMAGERY IS APPROACHING THE
CYCLONE FROM THE WEST. AS THIS TROUGH MOVES BY THE DEPRESSION
TONIGHT....THE STRONG SOUTHWESTERLY UPPER-LEVEL WINDS THAT HAVE
BEEN PLAGUING THE SYSTEM WILL BE REPLACED BY STRONGER NORTHERLIES.
THEREFORE...LITTLE OR NO STRENGTHENING IS EXPECTED AND THE
DEPRESSION IS FORECAST TO BECOME A REMNANT LOW IN ABOUT 36 HOURS...
IF NOT SOONER.

THE TRACK FORECAST REASONING REMAINS UNCHANGED FROM THE PREVIOUS
ADVISORY. AS THE DEPRESSION BECOMES A MORE SHALLOW SYSTEM...IT IS
EXPECTED TO CONTINUE TO DECELERATE AND MEANDER UNTIL A COLD FRONT
APPROACHES THE CENTRAL ATLANTIC IN ABOUT 48 HOURS. THE NEW OFFICIAL
FORECAST IS A LITTLE SLOWER AND WEST OF THE PREVIOUS TRACK....CLOSE
TO THE 18Z UKMET SOLUTION.

FORECAST POSITIONS AND MAX WINDS

INITIAL 12/0300Z 30.0N 49.7W 30 KT
12HR VT 12/1200Z 30.0N 48.9W 30 KT
24HR VT 13/0000Z 30.1N 48.4W 25 KT
36HR VT 13/1200Z 30.4N 48.2W 25 KT...REMNANT LOW
48HR VT 14/0000Z 31.0N 48.2W 25 KT...REMNANT LOW
72HR VT 15/0000Z...DISSIPATED

The LLC has moved under the convection. No question now is a tropical storm. The question is will t numbers go up to get the nhc to upgrade?
