Flood & Hurricane Risk in Casper
Casper carries no hurricane or coastal risk given its landlocked, high-elevation interior location, but real, moderate wildfire and hail exposure and, most distinctively, a real, well-documented North Platte River flood risk that this record discloses honestly rather than assuming away given Casper's otherwise semi-arid climate.

Learn moreNo Hurricane or Coastal Storm-Surge Risk
Casper is landlocked, far from any coastline, at an elevation over a mile high -- this record's own research this pass found no evidence of hurricane or coastal-storm-surge risk, consistent with Wyoming's interior, high-plains location.
A Real, Cited "Moderate" Wildfire Risk
Casper is cited with a 'Moderate' wildfire risk, given Wyoming's hot, windy summers that can cause rapid changes to fire risk over the grasslands and rangeland surrounding the city. This record's own research this pass did not surface a comprehensive, current, Casper-specific structures-at-risk statistic -- a real, disclosed gap.
Real Hail Exposure, Including a Historically Significant 1986 Loss Event
This record's own research this pass found 47 hail reports cited within 10 miles of Casper's city center, with the largest cited report at 2.00 inches (approximately 14 years ago), and a historically significant 1986 hail-loss event that ranked third-largest in Wyoming at approximately $29.0 million in losses.
A Moderate Statewide Tornado Risk, Geographically Distinct From Casper
Wyoming averages approximately 12 tornadoes per year statewide, concentrated primarily in the Cheyenne Ridge area of southeastern Wyoming during May and June -- a real, disclosed geographic distinction from Casper's own central-Wyoming location, though the state overall is cited with a 'Moderate' tornado risk.
Casper's Real, Defining Hazard: The North Platte River
Casper sits directly on the North Platte River, whose spring snowmelt from surrounding mountain ranges is a real, documented seasonal flood driver. FEMA Special Flood Hazard Areas (Zone AE, a 1%-annual-chance flood zone) run along the river through Casper, with Zone AO areas cited in the city's western suburbs, and Natrona County has been included in real, documented federal flood disaster declarations, including 2023 flooding and a 1978 severe storms/flooding/mudslides declaration. This record's own research this pass found a cited estimated annual loss from inland flooding of approximately $18.7 million for Natrona County.
Key takeaways
- Casper carries no hurricane or coastal-storm-surge risk, given its landlocked, high-elevation interior location.
- A real, cited 'Moderate' wildfire risk and real hail exposure (including a historically significant 1986 loss event) are genuine, disclosed considerations.
- Wyoming's statewide tornado risk is concentrated in the Cheyenne Ridge area, geographically distinct from Casper's central-Wyoming location.
- Casper sits directly on the North Platte River, with FEMA-designated flood zones running through the city and real federal disaster declarations for Natrona County -- confirm a specific target property's current FEMA flood-zone status directly.
