Overview
- Forecasters say the coastal low should form off the Carolinas Wednesday into Thursday and strengthen offshore with peak impacts expected Friday into the weekend.
- Coastal flood watches, gale watches and high surf or rip‑current alerts are already in effect and some Mid‑Atlantic gauges are recording early tidal flooding.
- European (ECMWF) guidance trends closer to the coast and produces heavier rain and the potential for 60–70 mph gusts in places like Boston and Cape Cod while the GFS keeps the low farther offshore and limits inland wind and rain.
- A strong high over eastern Canada and a full moon will drive persistent onshore winds and higher tides, which will amplify tidal piling, beach erosion and the risk of multi‑day coastal flooding even if the storm stays offshore.
- Communities should prepare for travel disruptions, event cancellations, power outages and road closures at high tide, and expect forecasts to evolve as the storm's exact track becomes clearer.
