Primary hazards. Ranked.
Boston's most defining weather hazard. The winter of 2014-2015 dropped a record 110.6 inches on Boston — the snowiest winter in recorded history — paralyzing the MBTA for weeks and costing $1B+ in economic damage. Major blizzards (26+ inches) hit Massachusetts several times per decade. The February 2013 Nemo blizzard dropped 25 inches in 24 hours and produced hurricane-force coastal winds. Massachusetts's 1,500 miles of coastline are increasingly vulnerable as sea levels rise. Boston's harbor floods during major nor'easters and hurricane remnants — the January 2018 nor'easter produced the highest water levels at Boston Harbor since 1978. The South Shore, Cape Cod, and the Islands (Martha's Vineyard, Nantucket) face significant surge exposure from Atlantic storms. The Connecticut, Merrimack, and Blackstone rivers flood regularly. Tropical Storm Irene (2011) caused $120M in damage across western MA. The 2006 Mother's Day floods killed 1 person and caused $100M in damage in eastern Massachusetts. Urban flooding in Boston's low-lying neighborhoods and Worcester's valleys is increasingly common.

Insurance gaps
What your homeowner's policy doesn't cover.
Standard homeowner's policies in Massachusetts exclude flood damage. Flood insurance through the NFIP has a 30-day waiting period — it cannot be purchased when a storm is forecast. Check your declarations page annually to confirm your coverage limits and deductibles.
Not in your standard policy
Flood damage — requires NFIP or private flood policy
Earthquake damage — requires separate endorsement
Sewer & drain backup — requires endorsement ($50–$100/yr)
Landslide / mudflow — generally excluded
