Risk Overview

About Natural Disaster Risk in Ramsey County, Minnesota

Ramsey County faces substantially above-average U.S. risk

Ramsey County scores 94.62 on the composite risk scale, placing it far above the national average and earning a "Relatively High" risk rating. This elevated exposure is driven by exceptional tornado risk (98.70) and significant flood threat (93.80) that reflect the county's urban density and river exposure. Ramsey County represents one of Minnesota's most hazard-exposed areas.

Ramsey ranks among Minnesota's highest-risk counties

Ramsey County's composite score of 94.62 massively exceeds Minnesota's average of 42.38, ranking it in the state's top tier for natural disaster exposure. The tornado risk of 98.70 represents Minnesota's highest exposure, while flood risk of 93.80 reflects the Mississippi River's presence through the county. This exceptional vulnerability demands serious preparation from all Ramsey County residents.

Ramsey faces Minnesota's most concentrated urban hazard

Ramsey County's score of 94.62 substantially exceeds every surrounding county including Washington (data not provided in this set) and St. Croix to the east. The 98.70 tornado risk score represents the single highest hazard exposure of any Minnesota county, driven by the Twin Cities metropolitan area's expansive footprint and dense building stock. This exceptional position underscores Ramsey's unique vulnerability profile statewide.

Tornadoes and flooding threaten Ramsey County residents

Tornado risk reaches 98.70—Minnesota's absolute highest—reflecting Ramsey County's spring and early summer exposure to severe storms, hail, and potential large tornadoes that impact the Twin Cities metro area. Flood risk scores 93.80, driven by the Mississippi River and urban stormwater systems that can overwhelm capacity during heavy rain and snowmelt. Earthquake risk is elevated at 28.88 compared to most Minnesota counties, though still low in absolute terms.

Prioritize tornado and flood protection in Ramsey County

Establish a detailed family tornado plan with a safe room or basement shelter, and practice your plan seasonally—Ramsey County's exceptional tornado risk demands active preparedness. Verify that your homeowners insurance covers tornado damage, and obtain a separate flood insurance policy if your home is in a mapped flood zone or at risk from urban stormwater. Review coverage annually and after any property improvements to ensure protection keeps pace with home value and evolving risk.

Risk Verdict

With a national rank of 95th percentile, Ramsey County faces above-average natural disaster pressure across several hazard categories. High composite risk signals that multiple hazard types are elevated simultaneously; planning for more than one scenario is important in Ramsey County.

Hazard Breakdown

Tornado risk is Ramsey County's dominant natural hazard, ranked at the 99th percentile nationally under FEMA's National Risk Index. Flood ranks second at the 94th percentile nationally. Additional tracked hazards include wildfire (53th percentile), earthquake (29th percentile).

Preparedness Context

Ramsey County's primary hazard, tornado, ranks at the 99th percentile nationally. In Ramsey County, mobile homes and manufactured housing face significantly higher tornado risk than site-built structures; residents in these homes should identify the nearest permanent community shelter in advance. The secondary flood hazard at the 94th percentile nationally adds seasonal complexity to Ramsey County's preparedness calendar, since flood and tornado risk often peak at different points in the year. The highest-risk window for tornado fatalities is overnight, when Ramsey County residents may be asleep. A NOAA weather radio with overnight alert capability is the single most impactful low-cost preparedness step available to Ramsey County households.

Regional Context

Ramsey County falls 52.2 points above Minnesota's typical county risk level, which means the hazard environment here is notably more demanding than the state baseline.
