Overview
- The coastal low strengthened offshore Thursday and is expected to bring the first impacts late Friday with the worst conditions forecast for Saturday and lingering effects into Sunday and Monday.
- National Weather Service offices have issued high wind watches and coastal flood watches for parts of Massachusetts and Rhode Island ahead of sustained onshore winds and 40–60+ mph coastal gusts.
- Forecasters expect heavy rain concentrated in southeastern New England with roughly 4–6 inches possible near Boston and Providence and 2–4 inches in adjacent areas, raising urban and street‑flooding concerns.
- Coastal communities from the Mid‑Atlantic to New England are already seeing overwash and tidal flooding, and repeated high tides tied to the full moon increase the chance of road closures, property inundation, and significant beach erosion.
- Small shifts in the storm track could change who is hardest hit and forecasters are also watching for subtropical transition over the warm Gulf Stream, a development that could prompt NHC monitoring or naming if confirmed.
