“If you can see it, flee it; If you can hear it, clear it”

The 30/30 rule (rule 1 and 2) says to shut down when lightning is 10 km’s away. Use a “flash to bang” (lightning to thunder) count of five seconds equals 1.2 km’s. Keep an eye on the sky. Note when skies darken or gusty winds develop. Have a place of shelter in mind, and a plan to get there.

Rule 1: When you can count less than 30 seconds between the lightning strike and the thunder, the storm is less than 10 km away. There is an 80% chance the next strike will happen within that 10 km. It is time to take cover. But, often, it’s hard to remember to count off seconds, or how many, and keep tally of the score too, and pay attention to the game, and watch the sky, and so on. Too confusing! So, here's the trick. Sound can carry great distances when the atmosphere is stable and quiet, like early mornings. But sound doesn't travel nearly as far during a stormy afternoon. Essentially, if you can hear the thunder, you're in the strike zone. Take cover!

Rule 2: Wait 30 minutes after the last clap of thunder before resuming your activity. Naturally, watch for broken tree limbs, fallen power lines or flooding that may have been caused by the storm.


Move to a safe location:
A large permanent building or metal vehicle is best.
Unsafe places are near metal or water; under trees; on hills, near electrical/electronic equipment.

Lightning likes power lines, metal, electrical conductors, high places, prominent or tall objects. It looks for the easiest or shortest path to the ground.

Safe places are homes and buildings. Close windows and doors then stay away from them. Lightning can go through both. It can strike through walls too, so stay away from outside walls if you can. Most cars and trucks are safe too. The metal body shields the interior (the tires have no affect). If you're caught in the open, try a valley or ravine. Get low. If you're in a wooded area, hide near a small tree or shrub.

If no shelter is available, crouch down, feet close together with head tucked down. Don't lie flat. If you're in a group, spread out, so that individuals are several meters apart.

Don't be the tallest object around. Stay away from the tallest objects too. Don't carry softball bats, or an umbrella. Don't wear metal cleats. Don't go under a tree or by a metal fence. Don't take cover in a stand-alone shed.

More Canadians are killed or injured by lightning than by any other summertime weather event, and most of those affected are involved in a sporting event of some kind. Remember that even a small-for-his-age-nine-year-old is very tall when he is standing alone in centre field.
