Irma claimed the lives of at least four people in South Carolina, state and local officials confirmed Tuesday.
Two people died in the storm on Monday, state officials said: Zhen Tain, 21, of Florida, who died in a two-car wreck on Interstate 77 in Columbia, and Charles Saxon, 57, of Calhoun Falls, who died when a limb fell on him.
During a morning briefing on Irma's impact on the state, Department of Public Safety Director Leroy Smith attributed Tain's wreck to storm conditions. Smith said Tain was driving too fast, lost control of his car, sideswiped another vehicle, hit a guard rail and then overturned.Smith also said Tain had Florida tag registrations on his vehicle.
The City of Columbia said later Tuesday that Arthur Strudwick, a public works assistant superintendent in the forestry and beautification division, was killed in a single-vehicle accident Monday night on Farrow Road while traveling to a downed tree.
The Sumter County Coroner's Office said a 54-year-old man was found dead in his home Tuesday morning after suffering carbon-monoxide poisoning from a generator he was using after losing power.
Gov. Henry McMaster urged the public to use caution as they travel around the state in the aftermath of Irma.
"As people are returning back to their homes and businesses, there's probably a good bit of anxiety," McMaster said during a Tuesday morning press conference. "We want everyone to be safe."
