Overview
- Forecasters say a low will form off the Carolina coast Wednesday and strengthen offshore through Friday, with peak impacts most likely Saturday and Sunday.
- Coastal flood advisories, gale watches and high rip‑current warnings are already in effect from the Mid‑Atlantic into New England as tides and surf begin to rise.
- Major models diverge: the European (ECMWF) run brings the low close to shore for a stronger storm, while the GFS keeps it farther offshore and weaker, making local outcomes track‑dependent.
- New England is the likeliest area for major impacts, with forecasts showing several inches of rain for Boston, up to a foot on Cape Cod in some scenarios, strong gusts and 15–18‑foot offshore waves that will drive severe beach erosion.
- A prolonged onshore flow driven by a strong high pressure to the northwest and the coastal low, combined with full‑moon tides, raises the risk of stacked back‑bay flooding, travel disruption and road closures if the storm lingers near the coast, and forecasters say model agreement in the next 24–48 hours will be critical for local warnings.
