I heard it on his Facebook stream.

Forecasts err on conservative side to minimize what I call “The boy who cried wolf” effect.

Re: ATL: LAURA - Hurricane - Discussion
Laura may get a Michael like frictional assist which could help bring those Cat 5 winds to the surface.
Some evidence of that happening as cloud tops are getting colder as it approaches landfall.

Every storm has the golden runway at some point, and they have over done intensity on numerous storms. Try to be objective here, Laura is just a single storm.
Furthermore, I recall several discussions reminding of the fact that even 24-36 hour intensity forecasts are subject to appreciable error

Also remember that NHC is hesitant about upgrading to 5 off SFMR. Jose in 2017 had Cat 5 SFMR, as did Michael. Neither were upgraded operationally, and Michael's TCR stated that it was upgraded off information unavailable at landfall. So we'll probably need a dropsonde or multiple decisive readings if it is going to be upgraded.

Points that I never even considered.

In fact if I recall they had Marco forecast to nearly category two, which was an absolutely reasonable expectation but the storm managed to under-perform; they're usually pretty good with intensity but intensity is MUCH trickier than track in a lot of cases especially with narrow windows of favorable conditions

Colors of lost purpose on the canvas of irrelevance
Not a meteorologist, in fact more of an idiot than anything. You should probably check with the NHC or a local NWS office for official information.

Perhaps so. Havnt been able to keep up with data coming in. Have pressures continued a 2-3 mb drop per hour?

As I was saying a week ago, its just that time of the year that these things just find a way. Unfortunately, that came to fruition in the worse possible way. Stomach churning that people stayed at ground zero. She's a monster.

Tornadic cells in the northern quadrant are about to come onshore in the next couple of hours.

AF plane is finally closing in on Laura. Should be getting passes relatively soon.

Re: ATL: LAURA - Hurricane - Discussion
I hope people who decided to stay are watching and get out now, in a couple hours it’s probably too late. And that’s just for people who have transportation available, not everyone does. Have they evacuated all the hospitals in the area? That’s risky to do with critical patients.

I read an article today on a news site, don't remember which site, that said weather forecasting has been harder to predict recently due to the diminished air traffic as a result of covid. Evidently, plane traffic gives readings such as wind and other things that help forecasters to predict. Don't know if that relates here or not.
