ST. LUCIE COUNTY, Fla. (CBS12) — St. Lucie County officials are urging residents to stay off the roads unless travel is necessary, as significant rainfall and flooding affect the area.

Gov. Ron DeSantis issued Executive Order 26-227, declaring a state of emergency for St. Lucie County and six other Florida counties because of widespread flooding and threats to public safety and critical infrastructure.

The St. Lucie County Sheriff’s Office said numerous roads are flooded or impassable, with more rain expected through Monday night and Tuesday. Deputies and other personnel remain on duty and are coordinating with the Emergency Operations Center, the agency said.

Residents should also stay away from downed power lines and standing water near electrical equipment, and monitor official sources for weather alerts and road updates.

St. Lucie County Public Schools, county government offices and courthouses will be closed Tuesday, Nov. 3.
