4-Oct Wed 11aEDT - winds 45mph(75km/h), moving NNW 7mph(11km/h), pressure 1004mb. Center about 200miles(320km) NNW of St. Thomas, about 190miles(305km) NNE of San Juan, Puerto Rico. Still will pull rain up across Puerto Rico, Virgin Islands, and some of the neighboring Leeward Islands.

TS Watch Bermuda.

With the NE US / Atlantic Canada region: Still looks like will combine with another Low over the Atlantic and this Low / hybrid system will throw a lot of rain into the region. NWS/WPC already has excessive rainfall outlooks for the NE US for this weekend for localized flash flooding possible with 1-3" rainfall, could see higher amounts in isolated bands. Euro keeps 40-60mph wind gust extreme Eastern Maine and across East Canada, GFS with 40-50mph along US coast and across Eastern Canada. Final impacts subject to change this far out still.

This is not going to help the cone size average error radii at years end recalc's.

5-Oct Thurs 8pEDT - winds 50mph(85km/h), moving N 14mph(22km/h), pressure 1005mb. Center about 340miles(545km) SSW of Bermuda.


Scattered showers over Bermuda. Very/extremely disorganized. Wind shear will keep any re-organization at bay. Doesn't look like a classic tropical system. To be absorbed by another low as pivots into North America.

NHC says transitioning to extra-tropical cyclone (a type of Post Tropical cyclone. Extratropical cyclones generally more poleward and derive their energy from baroclinc processes (temperature difference between warm and cool air). Storm center still pulsing the tiniest of on/off storms near center, but otherwise rains off to the NW, N, and Eastern sides of mostly devoid center.

Philippe has been absorbed / become an occluded front between Bermuda and North Carolina. Since it's not the same system and possibly occluded front, that appears why NHC will not be issuing Post-Tropical regular advisory updates like usual but I'm not 100% on that. After Sandy (2012) they continued issuing regular but limited NHC advisories if a storm threatens land after that event.

For impacts into the NE US and Atlantic Canada, see local / national weather sources (ie: US see NWS and WPC). An NHC archive of advisories: https://www.nhc.noaa.gov/archive/2023/PHILIPPE.shtml?

At least it's not stronger or another Sandy. Otherwise we'd run into another communication of impacts breakdown since it just disappeared from the NHC site.
