THE INITIAL MOTION IS 290/11 BASED ON THE PAST 12 HOURS OF MOTION.
THE GLOBAL MODELS ARE IN GOOD AGREEMENT ABOUT A GRADUAL TURN TOWARD
THE NORTHWEST TO NORTH-NORTHWEST OVER THE NEXT 5 DAYS. THE
HURRICANE IS FORECAST TO MOVE AROUND THE PERIPHERY OF A DEEP-LAYER
ANTICYCLONE CENTERED SOUTH OF NOVA SCOTIA. AN APPROACHING
SHORT-WAVE TROUGH MOVING ACROSS THE EASTERN UNITED STATES IS
FORECAST TO BYPASS ISABEL ON ABOUT DAY 3...BUT THE NEXT SHORT-WAVE
TROUGH SHOULD PICK UP THE HURRICANE BY ABOUT DAY 5. THE OFFICIAL
FORECAST TRACK IS ADJUSTED SLIGHTLY TO THE EAST OF THE PREVIOUS
ADVISORY BUT IS STILL CLOSE TO THE WESTERN-MOST GUIDANCE WHICH IS
THE GFS MODEL. THE OFFICIAL TRACK FORECAST SHOWS A DECREASE IN
FORWARD SPEED FOR 3 DAYS FOLLOWED BY AN INCREASE IN FORWARD SPEED
ON DAY 4 AND 5. NOTE THAT THE 5 DAY FORECAST POSITION IS RATHER
CLOSE TO THE MID-ATLANTIC U.S. COAST.

FORECASTER LAWRENCE

OK, the trough that is supposed to be around according to the NHC at day 3 is forecast by them in this discussion to MISS Isabel. The problem is that Isabel is speeding up. Day 5 is too late for something to pick up Isabel. It's moving at 11KTS. This equals close to 13 mph. 13 mph times 24 hours is 312 miles per day. 312 miles equates to roughly 5 degrees of longitude. 24 hr position would be 68.7 not 67.3. 48 hr position would be 73.7 not 69.8. They mention a decrease in forward speed, but that is a heck of a decrease and they say not until day 3. They say the trough at day 5 picks it up. At this rate of speed, Isabel in partying on South Beach by day 5. I'm consfused to say the least. I'm also tired, so if anyone thinks something different, help me understand.

You are right. They or the models have not been able to calculate the speed of this hurricane right at all! It will make the difference in the long end and they have it wrong! No wonder why I don't agree with their predicition :lol:

What in the heck is Miles Lawrence talking about the GFS being the "westernmost" model tonight? The 00z LBAR proggs Isabel into Myrtle Beach...the A98 forecast landfall just east of Wilmington, and one of the BAMM models took Issy inland over Cape Hatteras..

My God...what in the name of God was Lawrence watching tonight? the Georgia Tech-FSU game on ABC??? :D :D

Yes, I agree, but they pulled it out in the end. Unlike the mighty Gators' 63-3 victory. Go Gators!!!!! :D

Well I read that paper on Annular hurricanes for the post the other day. If I remember right the models have a hard time with them. They can't forecast the intensity on those storms and maybe the forward speed also is hard to predict. Maybe I missed something in that paper and could be wrong.
