Hurricane IDA


ZCZC MIATCDAT1 ALL
TTAA00 KNHC DDHHMM
HURRICANE IDA SPECIAL DISCUSSION NUMBER  16
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL   AL112009
115 AM CST SUN NOV 08 2009
 
THIS SPECIAL ADVISORY IS BEING ISSUED TO ADJUST THE SHORT-TERM
INTENSITY AND TRACK FORECAST OF IDA. BASED ON THE OBSERVED 
INTENSIFICATION OF THE SYSTEM IN THE LAST FEW HOURS...THE INTENSITY
FORECAST IS RAISED TO 85 KT AT 12 AND 24 HOURS...WITH THE
POSSIBILITY THAT IDA COULD GET A LITTLE STRONGER THAN THAT SOMETIME
TODAY.  BEYOND 36 HOURS...THE INTENSITY FORECAST IS UNCHANGED FROM
THE PREVIOUS ADVISORY. 

BASED ON THE AIRCRAFT RECONNAISSANCE FIX AROUND 0600 UTC...WHICH WAS
ABOUT A HALF A DEGREE TO THE WEST OF THE FORECAST TRACK...THE TRACK
FORECAST HAS BEEN ADJUSTED WESTWARD THROUGH 24 HOURS...INCREASING
THE LIKELIHOOD THAT HURRICANE-FORCE WINDS COULD IMPACT THE
NORTHEASTERN YUCATAN PENINSULA.  THIS NECESSITATES THE ISSUANCE OF
A HURRICANE WARNING FOR A PORTION OF THE YUCATAN PENINSULA AT THIS
TIME.
