Hazard Breakdown

Wildfire risk is Foster County's dominant natural hazard, ranked at the 48th percentile nationally under FEMA's National Risk Index. Tornado ranks second at the 18th percentile nationally. Additional tracked hazards include flood (3th percentile), earthquake (1th percentile).

Preparedness Context

Wildfire is Foster County's top-ranked natural hazard at the 48th percentile nationally. Foster County residents should assess whether their property lies within or adjacent to a Wildland-Urban Interface (WUI) zone, where ember transport and rapid spread pose the highest risk. Alongside wildfire, tornado at the 18th percentile nationally means a multi-season preparedness mindset — fire season and flood or storm season often require different household plans. For Foster County households, a practiced evacuation plan — with a primary and backup route designated before a fire occurs — provides more protection than any structural improvement when a wildfire approaches fast-moving terrain.

Regional Context

The North Dakota county average exceeds Foster County's score by 14.8 composite points — placing this county in the lower-risk tier relative to its in-state peers.
