Thanks Derek, but I think Isabel will get above 100 KTS before weakening some just before landfall.

Weak cat-3: 115 mph
Moderate cat-3: 120-125 mph
Strong cat-3: 130 mph

DT says moderate....I say strong...either way it will be destructive :o

Agree Perry it doesn't matter it is dangerous anyway.

DT,

I do not start forecasting until about midnight. However, the trend captured by Cangialosi was correct for an intensifying system. However, the intensification tonight was not expected by us
