Wed 25Oct 5pEDT: winds 100mph(155km/h), moving NE 14mph(22km/h), pressure 969mb. Although models are still split on sending ENE or WSW directions this weekend, NHC has it curving back to the NW then back to the NE on their cone map.

Appears Tammy will be on the tipping point in steering flows so main culprit in model guidance issues there (but still expected to loose tropical characteristics this week and further weaken regardless of which direction heads):

Graphics from Philippe Papin tweet - one of the newer forecasters to join the NHC but has long record of creating helpful graphics to understand current setups: https://x.com/pppapin/status/1717327630343782837

Thurs 26Oct 5aEDT: winds 85mph(140km/h), moving N 12mph(19km/h), pressure 973mb. Becomes Post-Tropical (lost tropical characteristics) as runs into the front along with wind shear and dry air, therefore no more NHC advisories will be issued (although NHC says it may loose the front and reacquire tropical-subtropical characteristics briefly this weekend - those chances will be in the 2 & 8a/pEDT regular tropical outlooks (with % chance of formation maps)).

NHC gives Tammy 30% chance of reacquiring tropical / sub-tropical characteristics. Either way, Bermuda may see rain/wind from slow weakening system.
