Quick Answer
High ground locations can be crucial for surviving flash floods, and knowing where to find them can be a lifesaver. Look for areas above the floodplain, such as hills, ridges, or even the top of a large rock outcropping. Natural formations like these can provide a safe haven from rising waters.
Identifying Safe Locations
When searching for high ground, look for areas with elevation changes, such as hills, ridges, or bluffs. Steep slopes can be hazardous, but they also offer a good vantage point to spot rising waters. A general rule of thumb is to seek ground above the 100-year flood elevation, which is typically 10-20 feet above the surrounding terrain. Keep an eye out for natural formations like rock outcroppings, caves, or hollowed tree trunks, which can provide temporary shelter from the floodwaters.
Evacuation Techniques
When a flash flood warning is issued, evacuate immediately if you’re in a low-lying area. Drive to higher ground, but avoid attempting to cross swift water. If you’re caught in your vehicle, do not attempt to outrun the floodwaters. Instead, pull over and seek higher ground on foot. If you’re unable to escape by vehicle, look for a sturdy tree or a elevated structure like a bridge or an overpass to take shelter on. Avoid canyons and washes, as they are prone to flash flooding and can be deadly.
Warning Signs and Preparation
Warning signs of a flash flood include rapid water rise, decreased water clarity, and an increase in river or stream flow. If you’re in a flood-prone area, stay informed about weather conditions and sign up for emergency alerts from local authorities. Keep a flood emergency kit in your vehicle, including items like a first aid kit, flashlight, and whistle. When exploring areas prone to flash flooding, stay alert for changing water levels and avoid traversing swollen streams or rivers.
