Background

This event follows earlier reports of a prolonged fall nor'easter battering Massachusetts with extreme rainfall and high winds on September 27, 2026. Previous coverage noted record rainfall in Sharon (9.41 inches) and coastal flooding, with forecasters warning of continued high tides and heavy rain through Monday. The current data provides a detailed breakdown of rainfall totals across the state as the storm weakens.

Why it matters

The significant rainfall totals, particularly in the South Shore and coastal areas, have led to flooding, travel disruptions, and potential property damage. The uneven distribution of rain highlights the localized impact of the storm, with some areas experiencing much heavier precipitation than others. This data is crucial for understanding the storm's impact and for future planning and preparedness.

What to watch

Forecasters expect the storm to weaken by Tuesday, but continued high tides and heavy rain may persist through Monday. Residents in areas with high rainfall totals should monitor for flooding and be prepared for potential power outages and travel disruptions.
