Tropical Major Hurricane Grace

Satellite-derived wind data from this morning indicated that a
small area of low pressure has developed along a tropical wave
about 1200 miles east of the Lesser Antilles. However, the low
does not quite have a closed circulation, and the associated shower
and thunderstorm activity remains disorganized. Environmental
conditions are expected to become more conducive for additional
development, and a tropical depression is likely to form by the
weekend while moving generally westward at about 20 mph across the
tropical Atlantic. This system is expected to reach portions of the
Leeward Islands late Saturday or early Sunday, and interests there
should monitor its progress.
* Formation chance through 48 hours...medium...60 percent.
* Formation chance through 5 days...high...70 percent.

Now 60/70.
 
The 12z GFS had an interesting track with what will be Grace!
 
A small low pressure system located about 1100 miles east of the
Lesser Antilles is producing disorganized shower and thunderstorm
activity primarily west of the center. However, environmental
conditions are expected to gradually become more conducive for
additional development, and a tropical depression is likely to form
by the weekend. The system is forecast to move generally westward at
about 20 mph across the tropical Atlantic, reaching portions of the
Leeward Islands late Saturday or early Sunday, and interests there

So far the GFS is starting to get on board on the system. 66 hours:

The GFS is doing something weird. It basically stalls Invest 95L near the Bahamas.

Clearly an outlier … but one could wonder .. is this going to be the next most talked about weather event … I’m certainly loving model watching checking every frame .. haven’t had the urge to do that in a while .. especially know it’ll all probably be gone in 6 hours

Landfall. Basically pulls a Dorian over the Bahamas and a Florence by hitting NC.
 
Yeah that GFS run was ROUGH for MBY....sitting right over my house around 962 MB.......prolly be a windy day.....

Honestly thats my worst case scenario landfall and approach for the Pamlico sound and Emerald Isle area and then up into my area.....a landfall like that would pile the water into the upper Pamlico sound and Tar river, then probably bring strong hurricane force winds into most of eastern NC east of 95 and one that big maybe all the way to RDU.....one of these days this is gonna happen....that run had legit 100-120 knt 850's well inland yikes.....

Toss in 9-15" of rain from the Triangle east cause thats what we really need down this way :rolleyes:
