Re: Tropical Wave in the Central Atlantic (10/60)
The GFS has been pretty consistent with this for the past few runs now, forming north of the lesser Antilles/Puerto Rico and becoming a low-end hurricane in the subtropics.

Re: Tropical Wave in the Central Atlantic (10/60)
2 PM TWO doesn't have anything new.
Near the Leeward Islands in the Tropical Atlantic:
A tropical wave located over the central tropical Atlantic continues
to produce a broad area of disorganized showers and thunderstorms.
Environmental conditions appear conducive for gradual development of
this system, and a tropical depression could form late this week or
over the weekend while it moves near or to the north of the northern
Leeward Islands.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 7 days...medium...60 percent.

Re: Tropical Wave in the Central Atlantic (10/70)
This could be a possible low end hurricane for Bermuda

Re: Tropical Wave in the Central Atlantic (10/70)
At this point this is mainly between a Bermuda/Atlantic Canada threat and total recurve if it develops at all, at least based on ensembles. GFS ensembles send a strong TS to Cat 1 Hurricane towards Bermuda's vicinity before giving Newfoundland and Nova Scotia some much-needed rain, while the Euro members that do develop trend east of Bermuda and OTS:

Re: Tropical Wave East of the Leeward Islands (40/70)
For some reason, this 40-70 wave (which models do show developing in a few days) is STILL not an invest. Also Recon is scheduled for tomorrow for this system so why are nhc so hesitant with the invest tag for this one? Im a bit at a loss tbh.
. Im sure it will be tagged sometime today but I just found it strange since its been on the AOI map for a while now

For those who want to start the invest 90L thread, here is a tip.
90L will appear on the list between 99L and 05L which is Erin. Keep refreshing.

Re: Tropical Wave East of the Leeward Islands (40/70)
No invest is crazy, but even crazier is the vast difference between the GFS solution and other models. GFS has a cat 2 direct hit on Bermuda and the others barely show a depression.
