Hundreds of thousands of Bay area residents are spending another day without power after historic Hurricane Irma slammed the Sunshine State.

TECO has restored power to many of its customers, but about 191,000 remained in the dark Wednesday.

Duke Energy has nearly a half-million customers without power, with the largest number 311,529 in Pinellas County at 9 a.m. Wednesday.

The governor's office said Tuesday afternoon that 12 people have died as a result of the storm. Six of those deaths were vehicle-related, four were during storm preparations, and one person was killed in an accident involving a power line.

One person died of a heart attack while trying to pull-start a generator, the governor's office said, adding that one person was killed in Pinellas, Pasco, Marion, Duval, Libery and Broward counties. Two people were killed in Hillsborough, Hardee and Orange counties. There were at least 35 Irma-related deaths in the Caribbean.

The White House said President Donald Trump will be coming to Florida on Thursday to talk with officials on cleanup efforts and visit with residents impacted by the storm. Trump has also approved a major disaster declaration, which authorizes federal funding to flow directly to Floridians impacted by the hurricane. The action also reimburses local communities and the state government to aid in response and recovery. 

The storm has affected the entire state. Jacksonville, for example, is experiencing its worst flooding since 1846, Scott said. Federal officials estimated one-quarter of all homes in the Keys were destroyed.

Duke Energy officials said Tuesday as many as 9,000 crew members are out in the fields working on downed lines and snapped power poles. Crew members were brought in from out of state and from as far away as Canada, said Duke spokeswoman Anna Gibbs. 

"We have 500 staff on duty working today in Pinellas and Pasco counties," Gibbs said.

TECO has crews fanned out across the region as well as close to 300,000 of its customers remain without power.
