Hurricane Milton updates: 16 dead across Florida in storm's aftermath

Jacksonville Mayor Donna Deegan urged residents to prepare for Hurricane Milton's impact in a press conference Tuesday.

Deegan asked residents to "batten down the hatches" and hunker down until conditions improve.

"We are expecting river flooding at the height of the storm, with peak tides carrying into Thursday evening," said Deegan. "We're asking everyone to stay off the roads. If you haven't already decided where you'll shelter, please do so now and stay there."
