As for the East U.S. Coast, the big question is timing. Timing of the trof/front along the east coast and Irma's arrival. A faster Irma and/or slower front/trof would mean recurve. If Irma is slower and/or the trof/front is faster, then high pressure builds north of Irma late next week, blocking recurve and shoving Irma west. I'm thinking that a US landfall is more likely than not, maybe 54% east coast landfall, 44% recurve, 2% into Gulf. I don't think that the timing is right for a Florida hit, as Irma may be north of 30N before it could be blocked. That puts SC northward under the gun.

Heading out on my bike shortly to survey the Brays Bayou flooding area. This is my first day off since weekend before last. Twelve days of 12+ hr shifts. Flooding is still bad here. Only 33" at my house. Wow! Only? Street flooding was all I saw here. However, 1/4 to 1/2 mile around me north or south and houses flooded. They're saying some homes may remain flooded for weeks on the west side.




Hopefully you are right about PR but our friends in the northern Leewards could see much more right? How you see things for Guadeloupe,Antigua St Marteen,St Barts BVI and U.S Virgin Islands?

think you're giving 40 basis points too many on a recurve. I do not see a viable recurve scenario


It's all about timing, as I said. When does Irma arrive where the trof could pick it up? Going to be close...

I think it's a simple case of cold water. It's started to look better almost the moment it crossed the 28C line and heading into warmer and warmer waters now.

Is it me or does it seem like it might be transitioning into an annular storm? It appears most of the banding has been shed and the new eye is quite large and expanding some on microwave imagery. It had a favorable environment for a transition into one so just wondering what others think?

Thanks Luis, very interresting post... because of there a LOT of uncertainties with cane Irma. WE SHOULD NOT LET OUR GUARD DOWN! Too close for any comfort and to be an early recurve scenario for most of us in the Leewards :roll: :oops:

The message is dont panic but start preparations just in case Irma goes to the Islands.

Looks like outflow from the CDO. The structure of it suggests that there is little shear

At least plywood for the windows.
You don't want to be in a long line at Home Depot later, or find out they ran out.
Can always store it somewhere.

Sump pump backup & spare batteries for it.

5-gal buckets to store fresh water.

5-gal bucket for potty and bleach to dump on it.

Canned food.


That's true about the plywood. You want to get it before they figure out a hurricane is coming and EVERYONE runs out to buy it! Then we affix the plywood on the windows with a product called PLYLOX (I THINK that's the name).

I don't know if this would be considered an "endorsement" of a product...I don't mean it to be. I just want to share about a great product I have used and love it.

They are just CLIPS. They go on the plywood and just sort of PUSH into the window casing. It's hard to explain. But I will tell you this: When I was divorced, and living alone and a hurricane threatened, I was able to put up ALL my window coverings in plywood using these plylox thingys. Took about an hour to do the whole house (10 windows) NO HOLES TO DRILL! I love them.

'Course the plywood had been cut to size beforehand. Leave about a half-inch clearance in the window casing. Also, they don't work if your windows DON'T have a casing (like in mobile homes). Cutting the wood to fit in the casings accomplishes another thing, too. You use LESS wood, as it's not having to go over the entire window opening and beyond (hope you can understand what I'm trying to say!).

DON'T WAIT until the winds are already gusting at 40 mph to try to make shutters!

You can buy Plylox at Home Depot, and Lowe's also I believe.

Fair enough...just a strange looking storm, LOL.

This far out, the best thing to do is get your home 'ready to get ready'. Trim branches in trees with thick canopies (they can become like sails and then the trees topple over) - you don't want a tree to crash through your roof with high winds ongoing. Pick up and put away anything in the yard that can become flying missiles (again you don't want something to come crashing through a window when high winds are happening. It costs nothing to do those things. If the storm doesn't head your way, then your yard is just nice and tidy! :) Get your insurance papers and other important papers together. Put them in a ziplock bag (waterproof - and cheap!). Make a Plan. If you have to evacuate, where will you go? How will you get there? Will you go to a family member's home further inland? A shelter? Families with members who have special needs should always think about their plan (and should find out if their city/county has a registry for them to be added to). Buy things that you can use later and that do not spoil. Bottled water. Canned goods (make sure you have a manual can opener). Think about things that do not need to be cooked - like peanut butter and crackers. If you have an infant, you want to make sure you have plenty of formula, baby food, diapers and wipes. Don't buy food that you and your family do not eat (if your family never eats tuna fish, this isn't the time to suddenly start). If you have children, get snacks and activities that keep them occupied. Walmart had little LED flashlights for $1 last year. I bought each of my grandsons one. I created a bag of treats and activities for each of them (the flashlight with a pack of batteries, coloring book with crayons, gummy snacks, new PJs, a game for each, box juice, etc). If you can afford it (and have a place to store it) a generator is a good investment - don't forget the gas! (Remember that you NEVER run it in a closed space!).

Hope this helps...
