45kt storm
I guess the hurricane models weren’t wrong saying she’d try to rapidly develop a compact inner core.

I am only a meteorology enthusiast who knows a decent amount about tropical cyclones. Look to the professional mets, the NHC, or your local weather office for the best information.

Re: ATL: JOYCE - Tropical Storm - Discussion
I'd put some weight into the SAR instrument, but there is some concern about it overestimating. Still, 50 kt seems reasonable, maybe 55 kt if that is a solid inner core on microwave.

Re: ATL: JOYCE - Tropical Storm - Discussion
And again. NHC refuses to up Isaac to C2 despite its gorgeous high-latitude presentation, now with Joyce, microwave showed a primitive eyewall and they hold it at 45 kt? What is going on? They didn't upgrade Ten-E to John until microwave showed an almost completely closed eyewall. I feel like I'm taking crazy pills. Am I the crazy one here? Genuinely losing my mind

For what it's worth, it looks like Isaac will be upgraded to a Cat 2 next advisory. Joyce is still at 45 kt though on the Best Track.

Got my eyes on moving right into Hurricane Alley: Florida.
Re: ATL: JOYCE - Tropical Storm - Discussion
The MDR curse still alive and well this season. Joyce struggling under shear in the tropical Atlantic whilst Isaac over-performs and strengthens to a cat 2 in the sub-tropics.

Re: ATL: JOYCE - Tropical Storm - Discussion
Looks like Joyce's is getting sheared with the convection pushed north leave the southern half of the circulation exposed.

SAR pass from a few hours ago, the southern side is indeed looking weak:

Re: ATL: JOYCE - Tropical Storm - Discussion
Joyce this morning looks like shear has made joyce pretty much naked with the convection been pushed to the north.

Re: ATL: JOYCE - Remnants - Discussion
Looks like Joyce may not be so dead, she has convection and shear seems to of ablated.
