Authorities in Florida say Hurricane Michael has killed at least 20 people in the state, bringing the overall death toll to 30.

Florida Emergency Management Division spokesman Alberto Moscoso says the state toll stood at 17 earlier this week. It included an additional death confirmed in Liberty County.

Those numbers come from fatalities confirmed as storm-related by district medical examiners, and include three more deaths to bring Bay County’s total to 15 deaths.

Those deaths were not reported to state emergency management officials. It wasn’t immediately clear why they were not yet added to the statewide tally.
