Lightning Threats and Safety Awareness
Lightning poses a significant danger all year round. In fact, last year marked an eight-year peak for lightning strikes in the United States, as reported by Vaisala Exweather.
Xweather has the most comprehensive lightning detection system globally, capable of tracking 99% of thunderstorms and capturing over 2 billion lightning events.
In a recent analysis, Vaisala Exweather predicted about 250 million lightning strikes in 2025, which represents a 20% rise compared to 2024.
The date with the most severe storms in 2025 was April 5. On that day, the Southeast faced 157 intense storms, including 21 tornadoes, resulting in over 3 million lightning strikes.
Texas reported the highest lightning activity last year, totaling 47 million strikes, while Rhode Island had the least, with only 8,000 incidents.
Interestingly, Shady Grove, Oklahoma, is recognized as the Lightning Capital of America with 1,160 recorded strikes, although in recent years, Texas and Florida have been notable contenders for this title.
According to NASA, lightning is an electrical discharge between clouds or between clouds and the ground. The rapid heating of the air from the lightning causes it to expand quickly, resulting in sound waves we know as thunder.
The National Weather Service (NWS) explains that lightning can occur between opposite charges within a thunderstorm cloud or between the cloud and the ground. Each year, around 25 million cloud-to-ground strikes happen in the U.S., and historically, there have been, on average, 51 fatalities due to lightning annually over the past three decades.
“Interestingly, most lightning victims don’t get struck during the storms at their peak intensity, but often before or after,” according to the NWS.
Safety Tips During Thunderstorms
The NWS recommends seeking shelter in a secure building that has plumbing and electrical systems, like schools, shopping malls, and homes, during thunderstorms.
When lightning hits a structure, electrical currents are routed through pipes and wires safely underground.
Since 2001, the NWS has observed a week in June to raise awareness about lightning safety, highlighting that it is often underestimated as a hazard.
