How Likely Is a Tornado in Morrill County, NE?
Morrill County, NE: what NOAA's tornado record says
Morrill County has recorded 55 tornado touches in NOAA's 76-year database, a rate of roughly one every 1.4 years - our High band. Put another way: Morrill County sees more tornado activity than 90% of US counties. Within Nebraska alone, Morrill County ranks 18 of 93 counties for tornado frequency.
Beyond the frequency band: violent history
1 tornado touching Morrill 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 Morrill County's rating leads to
Nationally, storm shelters and safe rooms run $2,890-$13,280. Because Morrill County is in Nebraska, the Nebraska Emergency Management Agency's Residential Tornado Safe Room Program can cut that by 75%, to about $722.5-$3,320 net - check current funding status before counting on it.
What a direct hit isn't required for
4,485 people live in Morrill County, and a tornado outbreak's power loss usually reaches far more of Nebraska 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 Morrill County's number: it is county-wide, and it covers about 1,424 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. Morrill County has about 4,485 residents.
