The world’s longest known lightning bolt-a staggering 515 miles long-went undetected for years until a revisit of data from NOAA’s GOES-16 satellite revealed its record-breaking length. This discovery highlights both the power of advanced whether monitoring technology and the increasing intensity of extreme weather events.
The lightning strike occurred on October 22, 2017, stretching from eastern Texas to near Kansas City, Missouri. It significantly surpassed the previous record,a 477-mile strike in Texas,louisiana,and Mississippi in 2020. The World Meteorological institution (WMO) formally confirmed the new milestone, classifying both the 2017 and 2020 flashes as “megaflashes” due to their exceptional length and duration.
Randall Cerveny, a professor and expert in weather extremes with the WMO, noted that technological advancements are allowing scientists to better identify and assess extreme weather phenomena. “This new record clearly demonstrates the incredible power of the natural habitat, and it is likely that even greater extremes still exist,” he stated.
The GOES-16 satellite, launched in 2016, is the first in a series of four sophisticated weather observation satellites. these satellites provide continuous monitoring of Earth’s weather patterns, aiding in both forecasting and understanding of climate change.
The increasing frequency of extreme weather events, including megaflashes, is a concern as these events cause billions of dollars in damage and pose a threat to life. The U.S. experiences hundreds of lightning-related fatalities and thousands of injuries annually, underscoring the importance of continued research and improved warning systems.

Understanding the Megaflash: A New Lightning Record
On February 7,2020,a single lightning flash shattered previous records,stretching an amazing 515 miles (828 kilometers) across Texas and Louisiana. Officially recognized by the World Meteorological Organization (WMO) in 2024, this event redefined our understanding of lightning’s potential reach. This wasn’t a typical cloud-to-ground strike; it was a megaflash, a relatively newly understood phenomenon. The previous record for the longest lightning flash was 477.2 miles, set in Brazil in 2018. This new record represents a significant jump in observed lightning distance.
How Was This Record Confirmed?
The confirmation of this record-breaking lightning bolt wasn’t based on visual sightings. Instead, it relied on data collected by the geostationary Lightning Mapper (GLM) instrument on the GOES-16 satellite.
Here’s a breakdown of the process:
- GLM Technology: The GLM detects the infrared and visible light flashes produced by thunderstorms. it doesn’t pinpoint where lightning strikes, but rather detects the optical emissions from them.
- Data Analysis: Scientists at the National Oceanic and Atmospheric Governance (NOAA) meticulously analyzed the GLM data, identifying and measuring the length of the megaflash.
- Verification: The WMO’s Regional specialized Meteorological Center (RSMC) – Americas, verified the data and officially recognized the new record. This involved rigorous quality control and cross-validation.
- Distinguishing megaflashes: Megaflashes are different from typical lightning. They are horizontal continuous flashes, lasting for several seconds, and occurring within the cloud or between clouds.
The Science Behind Megaflashes: Why so Long?
Customary lightning strikes typically travel a few miles. So, what allows a megaflash to span hundreds? Several factors contribute:
Atmospheric conditions: Stable atmospheric layers can act as waveguides, channeling the electrical discharge over vast distances.
Charge Structure within Storms: Supercells and mesoscale convective systems (MCSs) – large, organized clusters of thunderstorms – are more likely to produce megaflashes due to their complex charge structures.
Intracloud Lightning (IC): The 515-mile flash was primarily an intracloud lightning event, meaning it occured within the cloud rather than between the cloud and the ground. IC lightning tends to be more extensive than cloud-to-ground lightning.
Mesoscale convective Systems (MCS): These large weather systems create an surroundings conducive to the growth of long-duration, large-scale lightning.
Lightning Safety: What Does This Mean for You?
While a 515-mile lightning bolt is an extraordinary event, it doesn’t change the fundamental rules of lightning safety.
Here are crucial safety tips:
“When Thunder Roars, Go Indoors!”: This is the golden rule. Seek shelter inside a significant building or a hard-topped vehicle.
Avoid Water: Water is an excellent conductor of electricity. Stay away from pools, lakes, and beaches during a thunderstorm.
Stay Away from Tall Objects: Trees,poles,and other tall objects can attract lightning.
If Caught Outdoors: Crouch down low to the ground, making yourself the smallest target possible. Avoid lying flat.
30/30 Rule: If you can count less than 30 seconds between seeing lightning and hearing thunder, the storm is close enough to be perilous. Wait at least 30 minutes after the last thunderclap before resuming outdoor activities.
Real-Time Lightning Tracking: Resources to Stay Informed
Want to monitor lightning activity in real-time? Several resources are available:

Weather Channel & AccuWeather: these popular weather websites and apps provide real-time lightning tracking as part of their weather coverage.
The Future of Lightning Research
The finding of megaflashes has spurred further research into the physics of lightning.Scientists are using advanced satellite technology and ground-based observation networks to better understand:
Lightning Initiation: How do thunderstorms generate the initial electrical charge separation that leads to lightning?
Lightning Propagation: How does lightning travel through the atmosphere, and what factors influence its path?
Climate change & Lightning: Is there a link between climate change and the frequency or intensity of lightning events?
Improved Forecasting: Can we develop more accurate lightning forecasts to improve public safety?
Lightning: Electrical discharge caused by imbalances between storm clouds.
Megaflash: An exceptionally long-duration and extensive lightning flash.
Intracloud Lightning (IC): Lightning that occurs within a single cloud.
