Hurricane Sally moved northeast on Thursday, where it was expected to bring more than 300mm of rainfall to some areas a day after it flooded streets and knocked out power to hundreds of thousands of homes and businesses on the Gulf Coast of the United States.
Sally made landfall early on Wednesday near Gulf Shores, Alabama, with winds clocked at 169km/h (105mph) making it a Category 2 storm on the five-step Saffir-Simpson scale of intensity.
As of late Wednesday, it was moving north at 19km/h (12mph) after being downgraded to a tropical depression, the US National Hurricane Center said, with maximum winds of 50km/h (31mph).
The storm is believed to have killed one person in Alabama.
“We had a body wash up. We believe it was hurricane-related, but we have no definitive proof of that right now,” said Trent Johnson, a police lieutenant in Orange Beach, Alabama.
Some parts of the coast were inundated with more than 600mm of rainfall, as the slow-moving storm flooded communities. The coastal city of Pensacola, Florida, experienced up to 1.5 metres (5 feet) of flooding, and travel was cut by damaged roads and bridges. More than 570,000 homes and businesses across the area were without power.
Several residents along the Alabama and Florida coasts said damage from the storm caught them off guard. By late Wednesday, the floodwaters had started to recede in some areas, though the National Weather Service warned that extensive river flooding would be a concern through the weekend.
“It was just constant rain and wind,” said Preity Patel, 41, a resident of Pensacola for two years. “The water drained pretty quickly, thankfully. It’s just clean-up now.”
The Pensacola Bay Bridge, also known as the Three Mile Bridge, was missing a “significant section”, Florida Governor Ron DeSantis said at a news conference.
Electrical crews from other states arrived in Pensacola as utilities began restoring power to Alabama and Florida, according to local utilities.
“This year we’ve just got hurricane after hurricane,” said Matt Lane, 23, a member of a crew from New Hampshire Electric Coop, who arrived late on Tuesday directly from Hurricane Laura recovery efforts in Texas.
Sally was the 18th named storm in the Atlantic this year and the eighth of tropical storm or hurricane strength to hit the US. There are currently three other named storms in the Atlantic, making it one of the most active Atlantic hurricane seasons on record.
Hurricanes have increased in intensity and destructiveness since the 1980s as the climate has warmed, according to researchers at the US National Oceanic and Atmospheric Administration.
Sally shut more than a quarter of US Gulf of Mexico offshore oil and gas production.
