Lake County, Minnesota

County storm and disaster record · FIPS 27075 · population 10,884 · 2,109 sq mi

NOAA's Storm Events Database holds 618 records for Lake County, Minnesota from 1950 through June 30, 2026, on 380 days; the most frequent are winter storm records (268 records). 456 of them are forecast-zone records, which the National Weather Service files once per zone: a county covered by several zones receives each one, so a single storm can add several records on the same day. The deadliest single record is the July 21, 2016 thunderstorm wind: 2 deaths and 2 injuries. FEMA has issued 12 declarations naming the county since 1972, 10 of them for natural hazards; the latest for a natural hazard was “Severe Storms and Flooding” on June 28, 2024.
