How Likely Is a Tornado in Oregon County, MO?
How likely is a tornado in Oregon County, MO?
Oregon County has recorded 20 tornado touches in NOAA's 76-year database, a rate of roughly one every 3.8 years - our Moderate band. Put another way: Oregon County sees more tornado activity than 50% of US counties. Among 115 Missouri counties in this dataset, Oregon County ranks 76 for how often a tornado touches down.
Beyond the frequency band: violent history
11 weak and 9 significant tornadoes make up Oregon County's 20-track record - none violent. NOAA has never logged an EF4 or EF5 crossing this county.
The dollar figure Oregon County's rating leads to
Cost nationally: $2,890-$13,280, about $7,645 typical. Missouri 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 Missouri this pass.
What a direct hit isn't required for
Power loss after a tornado outbreak in Missouri often reaches homes the storm itself never touched. A battery-backup unit covers the outage without the fuel and venting a generator needs.
What this number is, and is not
One caveat before relying on Oregon County's number: it is county-wide, and it covers about 790 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. Oregon County has about 8,699 residents.
