How Likely Is a Tornado in Worcester County, MA?
Worcester County's tornado history, by the numbers
Worcester County has recorded 52 tornado touches in NOAA's 76-year database, a rate of roughly one every 1.5 years - our High band. Put another way: Worcester County sees more tornado activity than 89% of US counties. Within Massachusetts alone, Worcester County ranks 1 of 14 counties for tornado frequency.
Beyond the frequency band: violent history
1 tornado touching Worcester County reached violent (EF4-5) strength since 1950. That single fact carries more weight for the shelter decision than the county's overall frequency band.
The dollar figure Worcester County's rating leads to
Cost nationally: $2,890-$13,280, about $7,645 typical. Massachusetts has no state rebate program confirmed here; FEMA's underlying 75% cost-share exists nationwide, but applying through a state program is what usually makes it real, and none was found for Massachusetts this pass.
What a direct hit isn't required for
881,248 people live in Worcester County, and a tornado outbreak's power loss usually reaches far more of Massachusetts than the tracks themselves touch. A portable battery unit is the faster, no-fuel way to bridge that outage.
What this number is, and is not
One caveat before relying on Worcester County's number: it is county-wide, and it covers about 1,511 square miles, so a single touch counts the same as one in a county a fraction of that size. Weaker pre-1990s tornadoes are also documented as undercounted in NOAA's own record. Worcester County has about 881,248 residents.
