The Houston-based volunteer search-and-rescue network CrowdSource Rescue said its teams were trying to find about 2,100 people either reported missing or stranded and in need of help in Florida, co-founder Matthew Marchetti said.
Marchetti said his volunteer search teams, consisting mostly of off-duty police officers and firefighters, had rescued or accounted for 345 others previously reported to CrowdSourceMichael crashed ashore near Mexico Beach on Wednesday afternoon as one of the most powerful storms in U.S. history, with winds of up to 155 mph (250 kph).
The storm pushed a wall of seawater inland, causing widespread flooding.
The tropical storm, grew to a Category 4 hurricane.
More than 1,700 search and rescue workers have been deployed, Governor Rick Scott's office said in a statement.
More than 940,000 homes and businesses on the U.S. East Coast were without power and it could be weeks before power is restored to the most damaged parts of Florida.
