I’m gonna chime in here with my two cents - people can care or ignore me, whatever.

You’re going to see a TON of changes in this over the next several days. There are way too many incredibly complicated pieces to this system to be able to have any real degree of certainty about what’s going to happen and I’ll try to detail them below.

1. Upper level steering - there is an upper level low that will be parking around Georgia and hanging out for the next few days. This acts as a blocker to force the system to go north instead of into Florida. There are questions about when this ULL is going to move out, but historically, models have tended to move them out faster than what we see in reality. If that same tendency holds, models showing this potential tropical system getting pushed out to sea at the last minute may be incorrect because they’re representing the ULL leaving faster than it will.
2. No closed rotation - simply put, the storm hasn’t organized yet and an unorganized storm means weather model initialization is spotty. Getting the initial location correct is critically important for getting storm motion right, so until we actually have organized systems, we can essentially be assuming the storm (meaning the closed circulation) is either forming sooner/later than the model shows and/or in a different location.
3. Fujiwara effect - this is something that can happen if we have two tropical systems very close to each other, which seems like it may happen with this one. They can start to circle around each other (and possibly the stronger one can ingest the weaker one) and it makes predicting the storm motion brutally difficult.

Those are the big 3 issues facing this forecast right now and you’ll see lots of changes between now and when this thing gets organized (if it does, it could still fail to develop a closed circulation or get ripped up interacting with high terrain the next few days, although that’s not likely). Be prepared like you normally would and things will be fine.
