What stands out about Weymouth Town’s natural hazards
From FEMA’s model and FEMA’s records, below.
What Weymouth Town faces
Each hazard’s share of the building damage FEMA expects here, and how its rate compares with the rest of the country.
River and rain flooding
Hurricanes
Coastal flooding
Shares are of FEMA’s expected building damage, the measure the grade uses; ranks compare each hazard’s building-damage rate with all 85,154 U.S. census tracts. In FEMA’s terms, river and rain flooding is FEMA’s “Inland Flooding” (rivers and streams overflowing their banks, or rain overwhelming drainage). FEMA defines coastal flooding as high or rising tides and storm surge, so surge damage is counted there. Drought isn’t listed: FEMA counts its losses in crops only.

River and rain flooding is 75% of the building damage FEMA expects in Weymouth Town, and Weymouth Town’s rate of river and rain flooding damage is lower than 58% of U.S. census tracts. Coastal flooding adds 8%, at a rate in the top 3% of U.S. census tracts.
