Wow. HWRF has been on this for days now. Looking like 50 miles (pro from 2k's guess) across. That'll get some attention this afternoon.

Its forward speed will continue to slow down. That's the second biggest issue pre-landfall.




, her forward speed has actually picked up and will remain pretty constant through the next 72 hours. The slowdown/stall won't happen until then.

Did I miss something, or did the GFS kill Isaac off into South America?




You're correct. The "GFS" posted earlier is an experimental version.

You sure bout that? She was moving 13-14mph last night.

Whoops see the 15mph on the latest adv. I stand corrected.

She's still riding around the ridge, it shouldn't change too much in forward speed.

Can someone point me to the estimated wind speed maps? Will help me give better suggestions on the travel board thread

That's pretty imperfect at this juncture, since final location will matter so much, especially for Charlotte.

Wind speed probablites.

Reasonable onset time of winds.

Check local NWS pages closer in, as they might have actual wind projections.

EWRC vs dry air


This happens a lot in the Pacific. A storm will go through an ERC and then never fully pull it back together. ERC are still a bit of a mystery and not well understood, with regards to timing and why some are successful and others not.

The HWRF and the EURO pretty much have the same landfall point for Florence. Very similar inland movement too.

Euro and wind gusts:



HWRF at maximum intensity right before landfall:



HMON is also in remarkable agreement at the same hour:




I said it yesterday evening, but Wilmington +/- 50 miles is going to be ground zero.

It's a question that has caught my imagination over the years. If life ever has me researching hurricanes, it'd probably be the piece I'd want to focus on.

It's a worthwhile thing to use in conjunction with the other models, but it's quite the outlier for Isaac at this point.

Is Isaac just nothing to worry about anymore? Is it just going to dissipate?


The overnight models were a bit more aggressive with Isaac and now keep it together into the WCAB vs killing it off pretty quickly after entering the Caribbean.

Euro or GFS doing a better job?

It's fascinating to see the progress the NHC has made on forecasting locations vs intensity:





They've cut track errors in half or more over the last 30 years, but intensity projections have shown minimal improvement.

I haven't had time to dig that deep on Isaac but the same issues that are tripping up the GFS with Florence are probably causing the GEFS to have a north turn bias with Isaac.

Completely understandable. Didn't know if one model was significantly more reliable this year.

Seems everything is starting to agree if will go more southerly now.
