Summit County, CO Tornado Risk & Storm Shelter Cost
Summit County's tornado history, by the numbers

Nationally, Summit County ranks at the 3rd percentile for tornado frequency. Among 64 Colorado counties in this dataset, Summit County ranks 57 for how often a tornado touches down.
Summit County's EF4-5 history
Summit County's record has no EF4-5 tornado - its 0 tracks split 0 weak and 0 significant. That does not rule one out in the future, only that none has been recorded since 1950.
What a storm shelter costs near Summit County
For a Summit County homeowner, budget $2,890-$13,280 for a shelter or safe room ($7,645 typical) - this pass found no Colorado-specific rebate on top of FEMA's underlying 75% national cost-share program.
The outage nobody plans for
The storm that misses Summit County outright can still take its power out - outbreak-scale outages across Colorado are common well beyond the tracked path. A battery-backup unit handles that without a generator's setup or fuel.
Read this before you rely on it
This is a county-level figure, not a per-address probability. Summit County covers about 608 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. Summit County has about 30,882 residents.
