11 AM EDT TUE SEP 22 1998
 
JEANNE CONTINUES TO INTENSIFY.  A RATHER SOLID AND MODERATE-SIZED
CENTRAL DENSE OVERCAST IS APPARENT WITH A DISTINCT BAND TO THE NW
THROUGH NORTH.  T-NUMBERS ARE UP TO 3.5...SO 55 KT WILL BE THE
INITIAL WIND SPEED.
 
THE MOTION IS LITTLE CHANGED...295/15 KT.  THE 00Z NOGAPS SHOWS A
HIGH EXTENDING FROM NORTH OF JEANNE WESTWARD TO ABOUT 35W.  THIS
SHOULD KEEP THE STORM ON A WNW HEADING THROUGH 48 TO 72 HOURS.  THE
TRACK GUIDANCE AND OFFICIAL FORECAST ARE GENERALLY CONSISTENT WITH
THAT EXPECTATION.

FURTHER STRENGTHENING ALONG THE LINES OF THE SHIPS MODEL OUTPUT IS
SHOWN.
