989 cyclone south-southeast of Nantucket. Down 27 hPa in 24 hours. We’re a bit more than a Bergeron drop now. Bombs away.

Bumper crop of vultures at Hughes in Gburg. It’s still unclear if they’re using the windows for their reflection or hunting something up there. ¯\_(ツ)_/¯

Many Canadian observations keep dropping pressure — probably a QC flag in the MSLP and/or altimeter reading. This cyclone would realistically set November low pressure records for the southeast half of the island. They’re not that low.
The absolute low pressure for the island remains 940.2 hPa.

St. Pierre, in “oceanic France” just south of Newfoundland, dropped to 946 hPa as this cyclone passed by at 5pm their time (2000 UTC).
They do not seem to be part of the “funky” Newfoundland time zone.

While Post-T.C. Melissa remains hurricane-force well offshore the East Coast this morning, a cyclone nearly as deep continues to strengthen near the border of New England with southeast Canada.

Extratropical transition is clearly beginning. Vertical wind shear has increased. Interaction with the upper trough to the west has begun. Melissa’s moisture has reached New England as well. The storm could be post-tropical in 24 hours. 🐻⌚️

Melissa stopped on a dime and turned NNE.
The deluge is ongoing in Jamaica, with an intense feeder band aimed at Hispaniola; day 7 of rain there. Eastern Cuba should see its heaviest rain later today into tomorrow.
Water remains the deadliest hazard associated with tropical cyclones.

Melissa moves west, south of western Jamaica. The guidance generally is too early to recurve, but also not sharp enough with recurvature. One would think we’d have a better idea of whether or not a Jamaica landfall was certain tonight. Either way, Jamaica will see significant impacts. 🌊. 🐻⌚️
