Hurricane OPHELIA (Text)

ZCZC MIATCDAT1 ALL
TTAA00 KNHC DDHHMM
HURRICANE OPHELIA SPECIAL DISCUSSION NUMBER  31
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
530 PM EDT TUE SEP 13 2005
 
THIS SPECIAL ADVISORY IS MAINLY TO UPGRADE OPHELIA TO A HURRICANE
BASED ON RECENT REPORTS FROM BOTH NOAA AND AIR FORCE RESERVE UNIT 
RECONNAISSANCE AIRCRAFT DATA.  THE NOAA AIRCRAFT FOUND STEPPED-
FREQUENCY MICROWAVE RADIOMETER WINDS OF 63-66 KT NORTH-NORTHWEST OF
THE CENTER...BENEATH 4000 FT FLIGHT-LEVEL WINDS OF 83 KT. THE AIR
FORCE RECON FLIGHT-LEVEL WINDS OF 76 KT AT 700 MB IN THE SOUTHWEST
QUADRANT ALSO SUPPORTS HURRICANE INTENSITY.
 
GIVEN THAT OPHELIA IS ALREADY A 65-KT HURRICANE...IT IS QUITE
POSSIBLE THAT THE HURRICANE COULD REACH 70 KT BEFORE LANDFALL
OCCURS.
