The World Meteorological Organization (WMO) has officially confirmed a 2017 lightning flash in East Texas as the longest ever recorded. Spanning approximately 515 miles to Kansas City, it surpasses the previous record by a significant margin. The megaflash, initially missed in initial analysis, was identified using advanced satellite technology and its distance was measured using a consistent methodology. This record highlights both the power of nature and advancements in meteorological observation.
