2023 - tracking the tropics

It’s still east of NE verbatim, but was west overall in LF location—a direct hit on Nova Scotia as opposed to a track near/over Newfoundland at 12z and 06z. 

Really hard to figure out specifics of this steering pattern long range but the trend seems to be west the last ~36 hours.

Looks like it still has time per recon obs on that first pass. The first VDM is wild.
