if the last few frames on radar showing the outer eyewall closing off with deeper convection then thats no good.. once that inner eye stops "stealling" energy the outer eye can really intensify.

just have to wait some more..

It looks like what may have happened is after the EWRC completed yesterday, Irma made landfall and the old eye took back over? Now that conditions are more favorable, the old eye is dying out again and the new one taking back over?

Reported that 42,000 people already without power in Miami-Dade. And Irma is HOW far away still?
Even her outer bands are packing a pretty serious punch..

that outer eyewall sure looks to be getting much more intense.. needs to cut off the inner one to deepen rapidly

I live in the line of path of that confirmed tornado, and have relocated to the safest part of my house. I am close to Sawgrass Mall.

Which it looks like it is doing so currently. I believe this will take off soon, sadly. That big eye will show tonight.

The maximum elevation above sea level at Key West is about 18 feet, a 1-acre area known as Solares Hill.

Stay safe. Report in when over.

Watching a Key West web cam (Mallory Square) and have already seen two boats swept out to sea in the direction of Cuba.

The last EWRC took like 24 hours lol. Hoping this one does too so it doesn't have a chance to strengthen.

[weatherwindow]

Yellowlab,

I can't explain it. I grew up in Key West and for what ever reason the locals never evacuate. I was young when Donna came in and what you see now is what you would have seen then. No different when Betsy came through, locals are just that way.

The bathygraphic profile with the 600m depths of the Fla Straits just 6 miles offshore limits the surge profile to 11ft max Cat 5 surge w/astronomical high tide



Anybody know what the highest surge is on record for key west? Is it location and topography that make getting higher than 10 on key west difficult? I did some research and all I can find is 1846 storm that cleaned most of the island and residents fled to Solaris hill, and that says 8 ft. But I think Wilma was 8 feet, and they are saying 5-10 with this one. Not sure what Betsy was. I will say Wilma wouldn't have had as much battering waves as a storm like this. That may surprise residents who flooded in Wilma but may come back to a foundation.
