Should be shear-bait like Paloma.


It's interesting to see these late features pop up in places where they would have been real trouble just 2 months ago.

GFS vertical shear forecast is not looking so bad in this part of the Atlantic until the next big trough arrives this weekend. I'm guessing that is why it made it to invest status although I give it a low probability of ever developing. Even if it does its not coming close to the U.S and is a likely fish candidate.

For example here is 72 hours from now prior to trough arrival:

120 hours after trough passes:

The 12Z HWRF brings it into the Central Bahamas as a weak system before recurving, farther west than the BAMS and LGEM

let's hope the timing is right for everything if this indeed develops into something to keep it from hitting the Bahamas, Haiti, or the US. Remember if it hits the Bahamas that is not a fish.

Or Bermuda,if it develops at all. I am going to give it a 0.5% chance to develop,less than 57 :)

The NAM is more gunhoe on the 18Z run developing a tropical low heading into the Bahamas. Note giant trough to the NW..
