I'll give you a hint.

My home is exactly 4 feet above sea level. :eek:


West coast of FL surge probably less than Atlantic coast. Offshore winds during first half of event.

We lived near MM29 and checked Windfinder for Sunday's forecast....it was listing 24 ft seas....and we lived on the water. Scary stuff.

Pardner, we ain't going to escape this one either. North winds in excess of 90 mph will create a huge mess from Tampa Bay to Naples...remember, we are already super-saturated from all the rain last week. There is nothing holding those oak trees and other hardwoods up but sunshine and a prayer now. :double:

One thing to notice from the 18z GFS model is that it speeds up Irma, so this means that coastal SE FL could start feeling TS force winds as early as Saturday morning, with hurricane force winds at least in gusts by Saturday afternoon/evening then the worst conditions from around midnight Saturday night through at least noon on Sunday.
BTW, if you are wondering why it does not weakens Irma that much after making landfall is because it tracks it over the Everglades and Lake Okeechobee. A lot of flat wet lands.
Let me remind you that this could still change.

Wiki list of high points in FL, most of which are in the northern part. Bottom of the list is a whopping 49 feet above sea level. I would imagine a substantial surge could swamp across much of then southern part of the state.

Yup. Katrina intensified over the Glades and Wilma didn't lose any strength crossing over. The Everglades are nothing more than a fart in the wind when it comes to winding down hurricane intensity. Man are we paying for that 12 year hiatus for major hurricanes as it would appear now.

If Irma goes right up the coast of Florida this will be changed state to live here again.

Everyone I know on the barrier islands there is planning to evacuate to Georgia. During Matthew, almost everyone came inland and those who didn't wished they had. I had a friend whose entire fence disappeared from his yard in Indialantic during Matthew. This could be much worse.

Intensity is very very likely near correct. Warm water with low shear.


890mb as it makes landfall? I mean it's probably possible, but only a couple storms globally have ever been there. Not sure I can think of anything in the Atlantic proper.

The models have been consistently overdoing the pressure lately - same for Matthew and Harvey.

That would be barring any land interaction, right?

Starting to see some blue down the eye on JSL, usually sign of a storm getting very intense. Once she works out the eye maybe run at Cat 5? Strong Cat 4 at the least. I would not be sitting comfortable if I were in Florida right now. Good thing is time is on your side.

After Charley, I never dismiss intensity forecasts. The models back then missed the drop in pressure and rapid intensification from a Cat 2 to a Cat 4. I'll ride a 2 out, a 4? No freaking way.

Unfortunately the trends today are showing an increasing risk to Florida this weekend. I hope everyone over there will be preparing well ahead of time!
