Quick Answer
Weather conditions can significantly influence wilderness evacuation decisions, as severe weather can hinder evacuation efforts, increase the risk of injury or death, and pose a significant challenge to search and rescue teams.
Assessing Weather Risks
When evaluating the need for evacuation, assess weather conditions to determine the severity of the situation. A general rule of thumb is to be prepared to evacuate if heavy rain exceeds 2 inches per hour, sustained winds reach 40-50 mph, or snowfall totals 6-8 inches in a 24-hour period. In addition to these criteria, consider other factors such as lightning storms, flooding, and hypothermia risks.
Evacuation Strategies
Develop a contingency plan for evacuation, taking into account the weather conditions and the terrain. In areas where evacuation by foot or by vehicle is not feasible, use a combination of signals and communication devices to alert search and rescue teams. For example, use a whistle to signal for help at 3-minute intervals, and consider deploying a fire or a smoke signal during daylight hours.
Safety Priorities
Prioritize safety above all else when making evacuation decisions. Avoid traveling in extreme weather conditions, as this can increase the risk of accidents and injuries. If evacuation is necessary, move to a safe location, such as a nearby cabin or a vehicle, and wait for search and rescue teams to arrive. In areas with limited visibility, use a compass or GPS device to navigate to a safe location.
