US · Published Aug 27, 2026
Lightning strikes are a significant weather hazard in the United States, with approximately 25 million cloud-to-ground strikes occurring annually.
Lightning is generated when strong updrafts in storms carry water droplets high into the atmosphere, where they freeze and interact with downdrafts, creating a negatively charged storm base.

Impact & Risks

Lightning poses a severe risk to outdoor activities, especially during peak lightning season from June to August, when 70% of fatalities occur. So far in 2026, 12 fatalities have been reported, including recent incidents in Cape Charles, Virginia, and Florida. Tall objects, such as trees and buildings, are more likely to be struck, but lightning can also strike up to 25 miles away from a storm. The risk is particularly high in states like Florida and North Carolina, where frequent thunderstorms occur.
