Local Hazard History
Boston's defining hazard is the nor'easter — a coastal storm that can bury the metro in snow, flood the harbor, and cut power for days. The Blizzard of 1978 (February 6–7) dropped 27.1 inches on the city in roughly 32 hours, stranded about 3,000 cars and 500 trucks on Route 128, and killed 29 people in Massachusetts — several from carbon-monoxide poisoning in cars buried with their engines running. Decades later, the winter of 2014–2015 became the snowiest season ever recorded in Boston at 110.6 inches, with 64.8 inches in February 2015 alone, collapsing roofs and shutting the MBTA for days. And on January 4, 2018, a 'bomb cyclone' pushed Boston Harbor to 15.16 feet — the highest tide ever recorded (surpassing the 1978 record) — sending ice-choked seawater into the Seaport and downtown streets. In Boston the threat is wind, snow, and water, often at once.
