"A lightning flash can travel horizontally many miles away from the thunderstorm and then strike the ground. These types of lightning flashes are
called "Bolts from the Blue" because they seem to come out of a clear blue sky. While blue sky may exist overhead (or in part of the sky overhead) a
thunderstorm is always located 5 to 10 miles (and sometimes even farther) away. Although these flashes are rare, they have been known to cause
fatalities."
"The average lightning bolt is 6-8 miles long and can easily travel 25 to 40 miles horizontally prior to turning downward toward the ground. In
October 2001, the visual lightning detection system measured a single bolt that traveled from Waco to Fort Worth and then Dallas, Texas – a total
distance of more than 110 miles" |
