Grand County, UT Tornado Risk & Storm Shelter Cost
Grand County's tornado history, by the numbers
Since 1961, NOAA has logged 5 tornado tracks crossing Grand County - one about every 15.2 years, which lands it in our Minimal band. Nationally, Grand County ranks at the 15th percentile for tornado frequency. Within Utah alone, Grand County ranks 15 of 29 counties for tornado frequency.
Grand County's EF4-5 history
Grand County's record has no EF4-5 tornado - its 5 tracks split 3 weak and 2 significant. That does not rule one out in the future, only that none has been recorded since 1950.
What a storm shelter costs near Grand County
For a Grand County homeowner, budget $2,890-$13,280 for a shelter or safe room ($7,645 typical) - this pass found no Utah-specific rebate on top of FEMA's underlying 75% national cost-share program.
The outage nobody plans for
A direct hit is not required for Grand County to lose power - outbreak-wide outages across Utah regularly reach homes and businesses well outside the actual tracks. A battery bank covers that gap without a generator's fuel and venting needs.
Read this before you rely on it
This is a county-level figure, not a per-address probability. Grand County covers about 3,673 square miles, so a single touch here counts the same as a single touch in a county a fraction of that size. Pre-radar-era records (before the 1990s) are also documented by NOAA as undercounting weaker tornadoes in sparsely-instrumented areas. Grand County has about 9,788 residents.
