Howard County's EF4-5 history

What a storm shelter costs near Howard County

The storm that misses Howard County outright can still take its power out - outbreak-scale outages across Iowa 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. Howard County covers about 473 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. Howard County has about 9,360 residents.
