The National Weather Service will send a team to Indian River County Tuesday morning to confirm whether a tornado touched down in Vero Beach.
South of the Brevard-Indian River County line, damage was left behind in three mobile home parks.
At least 30 homes were damaged or destroyed Monday morning.
Roofs were peeled back and garages collapsed.
Joyce Marraccini told WFTV it only took a matter of seconds for her home to be torn apart.
"All that I know was that I was sitting there and my door flew right past me, and my car is underneath the porch," said Marraccini.
Deputies patrolled the neighborhood overnight to keep potential looters away.
