A Florida-bound storm has strengthened into Hurricane Nicole as it pounded the Bahamas, with US officials ordering evacuations that included former president Donald Trump’s Mar-a-Lago club.

It is a rare November hurricane for storm-weary Florida, where only two such hurricanes have made landfall since recordkeeping began in 1853 — the 1935 Yankee Hurricane and Hurricane Kate in 1985.

Nicole was expected to reach Florida late on Wednesday or early on Thursday with a storm surge that could further erode many beaches hit by Hurricane Ian in September before heading into Georgia and the Carolinas later on Thursday and Friday. It was expected to dump heavy rain across the region.

Nicole’s centre was about 75 miles (125 kilometres) east-northeast of West Palm Beach, Florida, late on Wednesday, the Miami-based National Hurricane Centre said. It had maximum sustained winds of 75 mph (120 kph) and was moving west-northwest at 13 mph (20 kph).

The sprawling storm became a hurricane as it slammed into Grand Bahama, having made landfall just hours earlier on Great Abaco island as a tropical storm with maximum sustained winds of 70 mph.

In the Bahamas, officials said that more than 860 people were in more than two dozen shelters. Extensive flooding, downed trees and power and water outages were reported in the archipelago’s northwest region.

In Florida, the St Lucie County Sheriff’s Office said in a tweet that the storm surge from Tropical Storm Nicole had already breached the sea wall along Indian River Drive, which runs parallel to the Atlantic Ocean. The Martin County Sheriff’s office also said seawater had breached part of a road on Hutchinson Island.

Residents in several Florida counties — Flagler, Palm Beach, Martin and Volusia — were ordered to evacuate such barrier islands, low-lying areas and mobile homes. Volusia, home to Daytona Beach, imposed a curfew and warned that intercoastal bridges used by evacuees would close when winds reach 39 mph.

Mar-a-Lago, Mr Trump’s club and home, is in one of those evacuation zones, built about a quarter-mile inland from the ocean. The main buildings sit on a small rise that is about 15 feet (4.6 meters) above sea level and the property has survived numerous stronger hurricanes since it was built nearly a century ago.

The resort’s security office hung up on Wednesday when an Associated Press reporter asked whether the club was being evacuated and there was no sign of evacuation by early afternoon.

At a news conference in Tallahassee, Governor Ron DeSantis said winds were the biggest concern and and significant power outages could occur, but that 16,000 linemen were on standby to restore power, as well as 600 guardsmen and seven search and rescue teams.

Forty-five of Florida’s 67 counties were under a state of emergency declaration.
