Facts about Thunderstorms

• They may occur individually, in clusters or in lines.
• Some of the most severe occur when a single thunderstorm affects one location for an extended time.
• Thunderstorms typically produce heavy rain for a brief period, anywhere from 30 minutes to an hour.
• Warm, humid conditions are highly favorable for thunderstorm development.
• About 10 percent of thunderstorms are classified as severe – one that produces hail at least an inch or larger in diameter, has winds of 58 miles per hour or higher or produces a tornado

Facts about Lightning

• Lightning’s unpredictability increases the risk to individuals and property.
• Lightning often strikes outside of heavy rain and may occur as far as 10 miles away from any rainfall.
• “Heat lightning” is actually lightning from a thunderstorm too far away from thunder to be heard. However, the storm may be moving in your direction.
• Most lightning deaths and injuries occur when people are caught outdoors in the summer months during the afternoon and evening.
• Your chances of being struck by lightning are estimated to be 1 in 600,000 but could be reduced even further by following safety precautions.
• Lightning strike victims carry no electrical charge and should be attended to immediately.
