Re: High pressure building....Fay will head west soon

The strengthening of tropical systems as they traverse South Florida does have recent precedence. TS Irene strengthed to Hurricane status while crossing from Naples/ Ft Meyers to Jupiter in 1998. Hurricane Wilma strengthed from a Cat 2 Hurricane to a Cat 3 Hurricane while crossing from Naples/ Ft Meyers to Jupiter in 2006




Sorry that is incorrect:

Wilma went from Cat 3 to Cat 2 as she crossed the state. I'm very familiar with this storm as it went right thru my backyard (literally!)

Irene simply maintained her Cat 1 status as she crossed, the pressured dropped, but only 1mb. Oddly I barely remember Irene at all.

Clearly a storm can strengthen over the Everglades & Lake O but I don't see any cases were it happened before on the scale we saw today. A 10mb pressure drop while over land for almost 12 hours is an extremely rare event (once in a hundred years maybe?)
