Uragano Gustav Cat. 2 landfall in Louisiana

**debris74** · 30/08/2008, 19:13

ricordo una cosa: che Joe Bastardi aveva detto cat. 5 prima di cuba!!!

DATA FROM AN AIR FORCE RECONNAISSANCE AIRCRAFT INDICATE THAT MAXIMUM
SUSTAINED WINDS HAVE CONTINUED TO INCREASE AND ARE NOW NEAR 145
MPH...230 KM/HR...WITH HIGHER GUSTS. GUSTAV IS AN EXTREMELY
DANGEROUS CATEGORY FOUR HURRICANE ON THE SAFFIR-SIMPSON
HURRICANE SCALE. AN UNOFFICIAL OBSERVATION OF A SUSTAINED WIND OF
140 MPH...220 KM/HR...HAS BEEN REPORTED ALONG THE EASTERN COAST OF
THE ISLE OF YOUTH. SOME ADDITIONAL STRENGTHENING IS FORECAST
DURING THE NEXT COUPLE OF DAYS...AND GUSTAV COULD BECOME A CATEGORY
FIVE HURRICANE EITHER BEFORE OR SHORTLY AFTER CROSSING WESTERN
CUBA.

molto sorpresi quelli dell'NHC:

HURRICANE GUSTAV SPECIAL DISCUSSION NUMBER 24
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL AL072008
200 PM EDT SAT AUG 30 2008

SO MUCH FOR A SLOWDOWN IN THE INTENSIFICATION RATE OF GUSTAV.
YESTERDAY AT THIS TIME WE CONVEYED THAT RAPID INTENSIFICATION OVER
THE NORTHWESTERN CARIBBEAN WAS POSSIBLE...BUT THIS IS A LITTLE MORE
THAN WHAT WE HAD IN MIND IN SUCH A SHORT TIME. THE HURRICANE HAS
REACHED CATEGORY FOUR STATUS WITH AN INTENSITY OF 125 KT...HAVING
BEEN A STRONG TROPICAL STORM JUST ABOUT 24 HOURS AGO. THE MAXIMUM
SURFACE WIND VALUE IS BASED ON A FLIGHT-LEVEL WIND AT 700 MB OF 141
KT...SINCE THE 90 PERCENT ADJUSTMENT TO THE SURFACE USUALLY WORKS
RATHER WELL FOR INTENSIFYING MAJOR HURRICANES. THE AIRCRAFT FIXES
INDICATE THAT A NORTHWESTWARD MOTION HAS RESUMED...AND THE INITIAL
MOTION ESTIMATE IS 315/12...RIGHT ALONG THE PREVIOUS ADVISORY
TRACK. NO CHANGES TO THE 1500 UTC FORECAST TRACK HAVE BEEN
MADE...BUT THE INTENSITY FORECAST HAS BEEN ADJUSTED UPWARD THROUGH
96 HOURS. GUSTAV COULD INTENSIFY SOME MORE DURING THE NEXT FEW
HOURS OVER WATER...AND ONE CANNOT RULE OUT CATEGORY FIVE INTENSITY
BEFORE CROSSING CUBA. THE FORECAST NOW CALLS FOR A PEAK AT 140
KT...CATEGORY FIVE INTENSITY...OVER THE SOUTHERN GULF WHERE OCEAN
HEAT CONTENT WILL STILL BE HIGH...FOLLOWED BY A VERY GRADUAL
WEAKENING OVER THE NORTHERN GULF WHERE OCEAN HEAT CONTENT IS LESS.
