A winter storm of potentially historic proportions that could rival the fabled Blizzard of 1978 headed into the SouthCoast on Sunday night into Monday morning, slamming Fall River with heavy snow, strong winds and blizzard conditions.

Strong east-to-northeast winds was predicted to trigger coastal flooding, especially along parts of Massachusetts.

The National Weather Service predicted "extreme" impacts from the storm, with one NWS map showing the potential for 18, 24 or even 30 inches of snow or more in the area.

Fall River Mayor Paul Coogan on Sunday declared a state of emergency for the city, followed by a similar announcement from Gov. Maura Healey at the state level. With the city still reeling from heavy snowfall earlier this winter, Coogan issued a driving ban for all non-essential workers from midnight Sunday to noon on Monday.
