How Likely Is a Tornado in Frederick County, MD?
How likely is a tornado in Frederick County, MD?
Frederick County has recorded 35 tornado touches in NOAA's 76-year database, a rate of roughly one every 2.2 years - our Elevated band. Put another way: Frederick County sees more tornado activity than 75% of US counties. Within Maryland alone, Frederick County ranks 1 of 24 counties for tornado frequency.
Beyond the frequency band: violent history
32 weak and 3 significant tornadoes make up Frederick County's 35-track record - none violent. NOAA has never logged an EF4 or EF5 crossing this county.
The dollar figure Frederick County's rating leads to
Cost nationally: $2,890-$13,280, about $7,645 typical. Maryland 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 Maryland this pass.
What a direct hit isn't required for
A direct hit is not required for Frederick County to lose power - outbreak-wide outages across Maryland regularly reach homes and businesses well outside the actual tracks. A battery bank covers that gap without a generator's fuel and venting needs.
What this number is, and is not
One caveat before relying on Frederick County's number: it is county-wide, and it covers about 661 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. Frederick County has about 299,317 residents.
