Paul, the cold front/trough/giant midwest storm system is what is going to push the system INTO Florida...not block it or protect it.
Oh...and just a few minutes ago...recon reported a pressure of 901MB, or possibly lower, with winds of atleast 150MPH. Winds are likely higher, and could end up exceeding 180MPH in a few hours.
Wilma is tied with Katrina as the 4th strongest storm (as measured by pressure on record)
This is a truely unreal hurricane season...3 of the top 5 strongest storms ever in just 6 weeks!!!!!!!
