If a 45-minute evacuation is required due to lightning, how far must the storm be?

• A. Within 5 miles
• B. Within 10 miles
• C. Within 15 miles
• D. Within 20 miles

Answer: (D)

The requirement for a 45-minute evacuation due to lightning is based on the understanding that lightning is a significant risk for spectators and participants at outdoor events. The general rule of thumb in meteorology is that if you can hear thunder, you are close enough to be struck by lightning. Typically, a 45-minute evacuation protocol suggests that the storm should be at a distance that is still a serious threat. Since the time frame indicates that the storm may potentially impact the area later, being within 20 miles is considered a safe threshold for evacuation. This distance gives organizers and safety personnel ample time to assess the situation and ensure safety protocols are in place, reducing the risks associated with lightning strikes. This guideline is often reinforced by meteorological organizations and sports safety management teams, aiming to protect the health and safety of all attendees. The choice of distance reflects a balance between the risk of lightning and the need for timely evacuation.
