I know it's a forum rule to not repost entire advisories or discussions but, I couldn't find a direct link to this discussion on the main page Unless you go through the NHC link. I left out the Lorenzo part.

TROPICAL STORM KAREN DISCUSSION NUMBER 12
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL AL122007
500 PM EDT THU SEP 27 2007

PERSISTENTLY STRONG SOUTHWESTERLY SHEAR CONTINUES TO AFFECT THE
TROPICAL CYCLONE...DISPLACING THE DEEP CONVECTION FROM THE
CIRCULATION CENTER. ALTHOUGH DVORAK SATELLITE INTENSITY ESTIMATES
FROM TAFB AND SAB HAVE DECREASED TO 45 KT...SOME RECENT DEEP
CONVECTIVE BURSTS NEAR THE CENTER SUGGEST A SLIGHTLY HIGHER
INTENSITY. THEREFORE...THE INITIAL WIND SPEED IS SET TO 50 KT.

THE INTENSITY FORECAST IS RELATIVELY STRAIGHTFORWARD THROUGH DAY
5...INDICATING GRADUAL WEAKENING. HOWEVER...LARGE-SCALE DYNAMICAL
MODELS...SHIPS...AND THE LGEM ARE NOW SUGGESTING THAT THE SHEAR
WILL BEGIN TO WEAKEN AROUND THE 96 TO 120 HR PERIOD WHEN THE
TROPICAL CYCLONE REACHES THE UPPER TROUGH AXIS. CONSEQUENTLY...
SLIGHT INTENSIFICATION IN THE LATTER PART OF THE PERIOD IS
POSSIBLE...ALBEIT NOT INDICATED IN THE OFFICIAL FORECAST AT THIS
TIME.

KAREN IS MOVING AT 305/11...WITH THIS GENERAL MOTION CONTINUING
DURING THE NEXT 2 DAYS OR SO AS KAREN PROPAGATES WITHIN THE
DEEP-LAYERED FLOW ASSOCIATED WITH THE SUBTROPICAL RIDGE TO THE
NORTH. THROUGH THE REMAINING PORTION OF THE FORECAST...THE
DYNAMICAL MODELS ARE AGREEING IN BUILDING THE MID- LEVEL RIDGE MORE
TOWARD THE NORTHWEST OF THE CYCLONE CAUSING KAREN TO TURN MORE
WEST-NORTHWESTWARD. THE OFFICIAL FORECAST IS CLOSE TO THE PREVIOUS
PACKAGE AND IS BASED ON A CONSENSUS OF THE MODELS.
