Looks like they are successfully working on the issues, a test VDM and a new set of AF obs just came in!

Hot Towers zooming around a mile a minute.
5000+ CAPE Infeed.
What else can you say but Rapid Intensification.

Just because we watch satellite presentations and are on weather forums doesn’t mean we know better than NHC. Let’s calm down with claims like that. You gotta remember that NHC would catch even more sh*t for too high an advisory or forecast than they would for one that seems too conservative. I was surprised Laura was only 110mph at 5AM but considering the fact that satellite presentation can improve well before wind speeds rise and the fact that the wind field is expanding as well, it’s very possible that winds aren’t as high as “they look” yet. Also we haven’t had recon for hours. Keep all these things in mind before you call NHC unethical. That sounds very histrionic.

This will be quite high-end. Getting ridiculous now.

They're not going to upgrade it when recon is in the storm, investigating the intensity. Better to put out a special advisory for an upgrade than guess at an upgrade and then potentially have to downgrade it again if recon finds lower (which has happened in the past).

It did take NHC the longest time to even forecast 100+ mph impacts, while HWRF was way above (it's actually pulled back some.) I don't envy the forecasters; especially when there are 3-4 conflicting major models to consider. I sometimes think the far out intensity projections at a point in time should be a range, like 100-120, not simply 100, when this happens.

HWRF probably gained a little reliability stature this go-round. That being said, I appreciate the professionals there, here, and everywhere trying their best. Stay safe everyone. hope folks got it together in time whatever plan they went with.

Let's say using the DVORAK estimation from the satellite and went with 130mph(just a guess) at 5am then recon finds the winds are 120mph, this could give the general public the impression the storm is weakening.

110 mph is an intense storm regardless. The NHC is the best in the world at making these calls, only a fool would question their judgement when a deadly storm is just off the coast.

Recon is up again. We should get an AF center pass in the next 20 minutes.

We'll get the special advisory soon enough. Just odd they wouldn't go ahead and bump it to "major" level given the way the media covers these things. But it's not a big deal with recon on the way already.

I just know how slow people can be to react to stuff like this.

Just woke up. This has the making of a monster. Very cold convection rotating around the eye, this is deepening fast

Looks like they're going in right now, AF has an extrapolated surface pressure of 968.6 mbar on tropicalatlantic.
