A lightning strike knocked three Boca Raton firefighters off their feet as they put out a backyard fire that had been ignited by a previous bolt. One of the firefighters was flung about 15 to 20 feet, and began having a seizure. The other two remained conscious. All three have recovered.

Florida ranks tops nationally for the number of cloud-to-ground strikes per square mile, with 1.2 million bolts per year.
