Miami, FL – If you were in South Florida on May 12, 1997, then you certainly remember this one. Usually by May, we in South Florida are thinking toward hurricane season and the perils it can bring. At around 2 p.m., an unusually strong tornado dropped just north of Coconut Grove, right over Silver Bluff Estates. It then crossed I-95, trekked into Downtown Miami, and entered Biscayne Bay. This tornado was strong by South Florida standards.
