Get ready for what Chelsea actually faces

A short kit for its top hazards, what to check before you buy, and where neighbors get alerts.

When the river rises
  • Turn around at flooded roads: a foot of moving water can carry off a car.
  • Flood insurance usually takes 30 days to start, so buy it before the forecast.
  • Keep papers and medicines up high, in a grab-and-go bag.
More from Ready.gov ↗
Tornado warnings
  • Pick your spot now: the lowest floor, an inside room, no windows.
  • A watch means be ready; a warning means take cover now.
  • Keep shoes and a flashlight by the bed.

Cold snaps
  • Let faucets drip so pipes don’t freeze.
  • Know where your water shutoff is.
  • Never heat the house with the oven or a grill.

Before you buy or rent
  • Look up the address on FEMA’s flood map.
  • Ask the seller or landlord whether it has ever flooded, and what flood insurance costs there.
  • Get a flood insurance quote early: policies usually start 30 days after you buy.

How to read this page

What these numbers can and can’t tell you

  • An average, not a forecast. FEMA’s National Risk Index estimates the damage 18 kinds of natural hazards cause in a typical year, from decades of records and models. A quiet decade can follow a bad year.
  • Compared by rate. “Higher than N%” compares yearly damage as a share of what’s there, so a big city isn’t rated riskier just for having more buildings.
  • Money that reached town. Flood claims are matched to Chelsea’s own flood-insurance community; household aid to the registrant’s city; repair grants to the City of Chelsea.
  • It follows property value. FEMA’s model weighs damage to buildings, so a place that recently lost many homes can rate lower than it feels. Across Chelsea, expected losses total about $2.2M a year, counting buildings, people and crops.
