Re: 185 MPH Severe Hurricane Irma Growing Closer and Larger


The NHS track has been virtually unchanged since the 8 p.m. advisory Wednesday night. I do notice, however, that they've predicted that her intensity will reduce (from a Cat3 to a Cat1 upon Georgia landfall)

If you are referring to NHC (?) .. be sure to always check the time stamps and positions when comparing Advisories. The NHC comparison you are curious about (between last night's 8pm and this morning's 5am) is hours apart, with the earlier Advisory still over water, and 5AM this morning further north - over land - because more time has passed.

5PM SEP 6 (Which would have carried over to 8pm)
120H 11/1800Z 31.0N 81.0W 105 KT 120 MPH

120H 12/0600Z 33.0N 81.0W 75 KT 85 MPH...INLAND

One location is still over water at 31.0N and the other over land at 33.0N.
