Editor's Notes
- #3 Lightning is one of nature's most awe inspiring and dangerous phenomenon. The average lightning flash could light a 100-watt light bulb for more than three months! The temperature of a lightning bolt may reach 50,000 degrees Fahrenheit which is hotter than the surface of the sun!
- #6 High places and open fields, isolated trees, unprotected gazebos, rain or picnic shelters, baseballdugouts, communication towers, flagpoles, light poles, bleachers (metal or wood), metal fences, convertibles, golf carts, water (ocean, lakes, swimming pools, rivers, etc.).
- #8 When inside a building AVOID:Use of the telephone or computer, taking a shower, washing your hands, doing dishes, or any contact with conductive surfaces with exposure to the outside such as metal door or window frames, electrical wiring, telephone wiring, cable TV wiring, plumbing, etc.
- #9 NO PLACE outside is safe when thunderstorms are in the area!! • If you hear thunder, lightning is close enough to strike you. • When you hear thunder, immediately move to safe shelter. • Safe shelter is a substantial building or inside an enclosed, metal-topped vehicle.
- #10 • Stay in safe shelter at least 30 minutes after you hear the last clap of thunder.
