How Likely Is a Tornado in Greenlee County, AZ?
Greenlee County's tornado history, by the numbers
In 76 years of NOAA/SPC tracking, Greenlee County has no recorded tornado track. Zero is the honest answer here, not missing data. Put another way: Greenlee County sees more tornado activity than 2% of US counties. Arizona has 15 counties in this dataset; Greenlee County ranks 15 of them by frequency.
Beyond the frequency band: violent history
0 weak and 0 significant tornadoes make up Greenlee County's 0-track record - none violent. NOAA has never logged an EF4 or EF5 crossing this county.
The dollar figure Greenlee County's rating leads to
Cost nationally: $2,890-$13,280, about $7,645 typical. Arizona 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 Arizona this pass.
What a direct hit isn't required for
A direct hit is not required for Greenlee County to lose power - outbreak-wide outages across Arizona 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 Greenlee County's number: it is county-wide, and it covers about 1,843 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. Greenlee County has about 9,410 residents.
