Thunderstorm-driven wind is the clearest hazard at Clara Barton National Historic Site, with Montgomery County recording 17 thunderstorm wind events in recent years alongside 6 floods, 5 flash floods, and 2 tornadoes. These storms move fast through the Potomac River corridor and have caused injuries in the surrounding area. The site's proximity to dense suburban Montgomery County also means a violent crime rate of 446.8 per 100,000 residents — well above national averages — making personal security part of your planning, not an afterthought.
When storms are forecast, delay your visit or keep a close eye on a weather-alert app like Weather.gov and stay away from the low-lying areas near the river where flash flooding channels quickly. Park in well-lit, visible spots close to other visitors, and avoid lingering after dusk when foot traffic drops. Keeping valuables locked out of sight in your vehicle reduces your exposure to opportunistic property crime common in high-traffic suburban park areas.
