Lightning can strike 5 to 10 miles in advance of the storm. If you feel your skin tingle and your hair stands on end, squat low to the ground on the balls of your feet, put your hands on top of your head and place your head between your legs. DO NOT LIE FLAT ON THE GROUND! Flash-to-Bang Ratio When you see lightning, count how many seconds until you hear thunder. If the time is 5 seconds, the lightning was one mile away; if it is 10 seconds, the lightning is two miles away. Seek shelter if the lightning moves to within four miles of your direction. Quickly go inside a completely enclosed building. If no enclosed building is convenient, get inside a hard-topped all metal vehicle. The “30-30 Rule” Take cover if you hear thunder within 30 seconds of the lightning flash. Wait at least 30 minutes after the last lightning flash or thunder before resuming normal activity. FLOODING In Colorado, river floods occur most often in association with snow melt in May and June. The flash flood season extends from May to September with July and August as the primary months. Flash floods result from heavy rainfall (especially in burnt areas), snowmelt, and dam/levee failures. Flash floods can erode an entire mountainside, roll boulders the size of trucks, tear out trees, roads and bridges, and cause the loss of lives. Rain-weakened soils can also result in mudslides capable of closing interstates and blocking escape routes.
