Risk Overview
About Natural Disaster Risk in Bryan County, Oklahoma
Bryan ranks notably above national risk baseline
Bryan County scores 74.55 on the composite risk scale, placing it in the "Relatively Low" category but well above the typical U.S. county's exposure. This elevated score reflects substantial tornado and wildfire threats that dominate the hazard profile.
Among Oklahoma's higher-risk counties
At 74.55 versus Oklahoma's 55.47 average, Bryan ranks in the upper tier of state risk, making it one of Oklahoma's more hazardous counties. The county faces particularly acute tornado exposure relative to its peers.
Bryan faces the region's most elevated risk
Bryan's 74.55 score significantly exceeds safer neighbors like Beaver (37.82) and Alfalfa (40.65), positioning it as the riskiest county in this regional analysis. Its tornado risk of 94.75 is the highest profiled.
Tornadoes and wildfires dominate Bryan's threats
Tornado risk at 94.75 is exceptionally severe—Bryan faces some of Oklahoma's greatest tornado exposure, requiring serious storm preparedness. Wildfire risk of 87.53 compounds the threat, creating a dual hazard environment that impacts most of the county.
Invest in tornado shelter and comprehensive coverage
Bryan County residents must prioritize homeowner's insurance that covers both tornado and wildfire damage, as both hazards pose substantial threats to properties. Build or designate a reinforced safe room capable of withstanding violent tornadoes, and create defensible space by clearing brush and dead trees 30-50 feet from structures; clear roofs and gutters of debris regularly.

Hazard Breakdown
Tornado risk is Bryan County's dominant natural hazard, ranked at the 95th percentile nationally under FEMA's National Risk Index. Wildfire ranks second at the 88th percentile nationally. Additional tracked hazards include earthquake (64th percentile), flood (54th percentile), hurricane (46th percentile).
Preparedness Context
At the 95th percentile nationally for tornado risk, Bryan County households benefit most from a reliable alert system — a NOAA weather radio that activates during overnight hours when residents may not be checking smartphone alerts. Wildfire is the second hazard driver for Bryan County at the 88th percentile nationally, meaning households should maintain awareness of both severe-weather and wildfire-specific warning systems. For Bryan County households, a pre-decided family shelter plan — who goes where, how children are retrieved from school during a warning, and a neighborhood meet-up point if phones fail — provides real protection that no supply kit alone can replicate.
Regional Context
At 19.1 points above the Oklahoma state average, Bryan County carries meaningfully higher natural disaster exposure than a typical Oklahoma county.
