ecco lo shear. potrebbe anche fare landfall come cat. 1:

si è attuale, ma lo shear nn svanisce in uno o due giorni perchè quella bassa a ovest del golfo nn puo sparire in così poco tempo. anche il bollettino ufficiale cmq ne tiene conto:
THE HEAT CONTENT DECREASES AND MOST MODELS INCREASE THE
VERTICAL WIND SHEAR NEAR GUSTAV DUE TO AN UPPER-LEVEL LOW OVER THE
WESTERN GULF
quella del landfall a cat.1 era una battuta, ma cmq devo dire che anche all'NHC hanno davvero fatto casino con le previsioni questa volta. questo si è riflesso sui mass media che stanno chiamando l'apocalisse:
'Mother of all storms' heads for Gulf Coast
A mass evacuation is under way along the Gulf Coast amid fears that Hurricane Gustav could strengthen by the time it makes landfall in the U.S. The mayor of New Orleans, which was devastated by Hurricane Katrina in 2005, called Gustav "the mother of all storms" and warned residents: "You need to be scared
forse era cmq necessario un'evacuazione totale ma se poi arriva come cat.1-2 la gente se la prenderà a morte e al prx uragano nessuno se ne andrà anche se sarà cat.12
questa animazione è incredibile.
