Dr. Gregory Forbes

"Tornadoes - Hawaii and Mainland" will provide an overview of where tornadoes have hit Hawaii since 1950 (there have been 42), their strength, and the types of thunderstorms that normally cause tornadoes in Hawaii. Dr. Forbes will then review the conditions that give long-track, violent tornadoes in the mainland of the United States and how those tornadoes form.
