Thunderstorm Safety — What to Do Before, During, and After

Before the Storm

• Check the forecast and be aware of thunderstorm risk
• Identify safe shelter: a substantial building or hard-topped vehicle
• Secure outdoor furniture and bring pets inside
• Charge your phone in case of power outages

The 30-30 Rule

If the time between lightning and thunder is less than 30 seconds, go inside. Stay inside for 30 minutes after the last thunder.

Lightning can strike up to 16 km from the rain core — so-called "bolts from the blue."

During the Storm

Indoors

• Stay away from windows, doors, and porches
• Avoid water — do not shower, wash dishes, or use plumbing
• Unplug sensitive electronics (or use surge protectors)
• Use a battery-powered radio for weather updates

If Caught Outside

• Do NOT shelter under isolated trees (the worst place to be)
• Move to the lowest point — a ditch or valley
• Crouch low with feet together, minimising ground contact
• Avoid open fields, hilltops, and bodies of water
• Drop metal objects (golf clubs, umbrellas, fishing rods)

Lightning First Aid

If someone is struck by lightning:

• They do NOT carry a charge — it is safe to touch them
• Call emergency services immediately
• Start CPR if they have no pulse
• Lightning strike victims can often be revived if treated quickly

After the Storm

• Wait 30 minutes after the last lightning before going outside
• Watch for downed power lines and flooding
• Check on neighbours, especially elderly people
