Risk Assessment for De Graff, Ohio
About De Graff, Ohio
De Graff is home to approximately 1K residents and features a temperate continental climate with four distinct seasons. Located within Tornado Alley, the area experiences some of the most intense severe weather events in the world.
De Graff sits within the central United States tornado corridor, where colliding air masses create ideal conditions for supercell thunderstorms and violent tornadoes. The region's flat terrain provides no natural barriers to severe weather systems, and the spring storm season can produce devastating outbreaks of multiple tornadoes in a single day.
Notable historical events affecting this area include the 1974 Xenia Tornado (F5, 34 deaths, destroyed half of Xenia, Ohio); the 2019 Memorial Day Tornadoes (EF4, 1 death, massive damage in Dayton metro area). These events underscore the importance of environmental risk awareness and preparedness for residents and property owners.

Understanding Risk Factors for De Graff
🌪️ Tornado Risk
De Graff lies within America's Tornado Alley, where warm Gulf air collides with cold Canadian fronts to create conditions favorable for violent tornadoes. Peak tornado season runs from April through June, though tornadoes can occur year-round. The area has implemented advanced warning systems and many communities have storm shelters.
🌊 Flood Risk
Flood risk in De Graff is assessed using FEMA flood zone data, historical flood events, and proximity to water bodies. Areas near rivers, coastlines, and low-lying regions typically face elevated flood potential. Local topography and drainage infrastructure play a significant role in determining neighborhood-level risk.
❄️ Winter Storm Risk
De Graff experiences severe winter weather including blizzards, ice storms, and dangerously low wind chills. Heavy snowfall can collapse roofs, ice accumulation can bring down power lines, and freeze-thaw cycles damage roads and infrastructure. Winter storm preparedness is essential for residents.
💨 Air Quality
Air quality monitoring in De Graff draws from EPA AirNow sensors measuring particulate matter (PM2.5), ozone levels, and other pollutants that affect respiratory health. Seasonal variations and agricultural or industrial activity can influence local air quality.
🔥 Wildfire Risk
Wildfire risk evaluation considers vegetation density, climate conditions, historical fire data, and terrain characteristics in De Graff. Seasonal weather patterns and local land management practices influence the area's fire vulnerability.
