Duke Energy expects to take at least four more days to restore electricity to many of its customers in Florida after Hurricane Milton caused power outages across the state, the U.S. utility firm said on Friday.

Florida’s two biggest utilities said the majority of their customers who lost power from Hurricane Milton will have it restored by early next week. Some are likely to be in the dark until Thursday.

Power can go out even before landfall, which is forecast for Florida’s Gulf Coast late Wednesday or early Thursday. Outages often happen when trees topple over power lines. High winds and over saturated soil weakening tree roots can create the perfect environment for flying debris to bring down those lines.

A crew of 19 Dixie Electric linemen are currently in Florida helping with power restoration after Hurricane Milton. One of these men, Brady Creel, is also scheduled to be married in less than a week.

Nearly half-a-million Floridians were still without power Monday morning, days after Hurricane Milton barreled through the state's west-central coast.

Residents in Florida are still struggling with the aftermath of Hurricane Milton with runoff from the heavy rainfall making its way into rivers and flooding inland communities. More than one million customers across the state are still without power in addition to gas shortages across the region.

Days after deadly Hurricane Milton slammed into Florida as a Category 3 storm with over 100 mph winds, near-record storm surge and a historic tornado outbreak that left nearly 4 million without power,
