Replaced by the September 22 evening outlook. These posts are kept for reference; expiry does not mean the storm has ended.
Latest outlook · September 22 afternoon
Southern New England: The 4:05 p.m. ADT GFS check keeps Boston’s sampled gust at 46 km/h but raises precipitation from 0 to 41 mm; Providence remains at 51 km/h and rises from 1 to 17 mm. NWS Boston’s September 22, 7:11 a.m. EDT discussion describes increasing confidence in an impactful late-week coastal storm, but low confidence in its exact track. Rough seas and coastal erosion remain concerns. Marine Gale Warnings cover September 23–24, with Small Craft Advisories in other waters; the listed beach rip-current risk covers September 22. No land wind warning was listed.
Maine & New Hampshire: Portland’s sampled gust remains 49 km/h while precipitation rises from 0 to 45 mm. NWS Gray’s September 22, 2:19 p.m. EDT discussion reports somewhat better ensemble agreement on how far north the low reaches, but continued spread over its offshore track or possible westward drift. Gusty coastal winds, high surf, rip currents and coastal flooding are increasingly likely; soaking rain remains track-dependent. A marine Small Craft Advisory now covers ANZ154 from 11 a.m. September 23 to 8 p.m. EDT September 24. Land Frost Advisories for parts of western Maine and central New Hampshire cover early September 23 and are unrelated to this storm.
New York / Long Island: NWS New York’s September 22, 7:29 a.m. EDT discussion retains a westward shift in its earlier model comparison. It forecasts potential high surf, beach erosion and minor to locally moderate coastal flooding, possibly starting September 23 afternoon. Marine Gale Warnings cover ocean waters from September 22 evening through September 24 afternoon, and selected sound and bay waters during September 23. A high rip-current risk covers September 22 and 23. These are marine and beach hazards; no land wind headline was listed.
Nova Scotia: The 4:05 p.m. ADT GFS check keeps sampled gusts at 32–74 km/h. Yarmouth precipitation eases from 28 to 19 mm, Halifax rises from 8 to 11 mm and the eastern samples remain at 0–2 mm. ECCC’s September 22, 4 p.m. ADT forecasts retain showers in Yarmouth and Halifax for September 25–26; Port Hawkesbury and Sydney turn from cloudy September 25 to showers that night and September 26. The Halifax-area feed displayed a frost advisory for the night of September 22; it is unrelated to the tracked coastal storm. The other three location feeds displayed no watches or warnings. This is a land-location check, not a marine all-clear. These are forecasts, not observed impacts.

NWS New York outlook. Rounded zero precipitation in the table does not mean there is no coastal or surf risk.
