Dealing with Severe Weather (United States Soccer Federation)

This position paper provides basic guidelines for dealing with lightning, windstorms, and other
severe weather conditions.

The peak season for severe weather occurs in the United States between May and August,
typically in the late afternoon and early evening.

Lightning.
Apply the 30-30 rule
When you see lightning, count the time until you hear thunder. If this time is 30 seconds or
less, seek proper shelter. If you can't see the lightning, just hearing the thunder is a good
back-up rule. Wait 30 minutes or more after hearing the last thunder before leaving shelter.
