How Hurricane Irma Can Cause Tornadoes

As the powerful and deadly Hurricane Irma makes landfall in Florida after causing devastating destruction in the Caribbean, forecasters are warning of another related danger: tornadoes.

The National Weather Service's Storm Prediction Center issued tornado warnings for a large swath of east-central and southern Florida late Saturday night, affecting cities including Miami. At least one reported tornado has already touched down in Oakland Park, Fla. as of Sunday morning.
