Tricky forecast and shows anything can still happen. Hopefully the 0z runs provide some clarity. Link to comment Share on other sites More sharing options...

I saw the post about 24 hours dropping to Cat 1 strength and wondered because it looked like in 24 from 2nd landfall, she'd be in western PA.

The phasing slows the weakening process and the system actually deepens again. Should point out the obvious that we shouldn't be putting a lot of stock in individual op runs yet, whether it's pre or post landfall. Link to comment Share on other sites More sharing options...

I noticed that too, I was curious how wide this storm was for hurricane and TS force winds. Seems to be broadening at least based on this early recon. We'll see how the flight pans out.

The NHC had been talking about forecasts for the wind field to expand and it has been fascinating to watch take place. This is also reflected in wind history.

I'd be interested in a more authoritative answer, but the way I have always understood it is that the shallow coastal waters in the gulf enhance surge. The E. Coast of FL gets much deeper much faster, so it's doesn't provide as much enhancement. I think the danger of neighborhoods well inland becoming flooded by surge is much greater on the gulf side. Of course the E. Coast has much greater population density right on the waterfront so there are plenty of structures and people in harms way.

NJwx85 Posted September 4, 2017 Author Share Posted September 4, 2017 Most of the GEFS match the OP, some slightly East, a few into the Gulf and a straggler or two into SNE. None are OTS. Link to comment Share on other sites More sharing options...
