Safety Moment: Flash Flooding

Flash flooding is one of the most dangerous events that can occur during outdoor activities; however, because it happens infrequently in most areas, it is often overlooked as a safety consideration. While the majority of fatalities occur inside vehicles attempting to cross floodwaters, significant risks remain for campers and hikers caught in mountain passes, dry riverbeds, or near rising streams during heavy rain.

SAFE PRACTICES

Before your activity, review the SAFE Checklist and check for local hazards. Certain seasons carry a higher risk of flash flooding. Research your destination to understand if the terrain or timing makes a flash flood more likely during your trip. Signs it may not be safe to go include:

• Unseasonable heavy rain over several hours or steady substantial rain over several days
• Heavy rains in conjunction with a spring thaw (hypothermia can also be an issue here)
• Water levels rising in usually dry or low running streams, creeks, and rivers
