Hurricane Sally, a plodding but powerful storm with winds of 85mph, is creeping towards the northern Gulf Coast with forecasters warning of potentially deadly storm surges, flash floods spurred by up to 2ft of rain and the possibility of tornadoes.

Hurricane warnings have been replaced by a tropical storm warning from the mouth of the Pearl River westwards to Grand Isle, Louisiana, including in New Orleans, the National Hurricane Centre said. A tropical storm warning west of Grand Isle has been discontinued.

Hurricane warnings had stretched from Grand Isle to Navarre, Florida, but forecasters — while stressing “significant” uncertainty — kept nudging the predicted track to the east.

That eased fears in New Orleans, which once was in the storm’s crosshairs, but it prompted Florida governor Ron DeSantis to declare an emergency in the Panhandle’s westernmost counties, which were being pummelled by rain from Sally’s outer bands early on Tuesday.

The threat of heavy rain and storm surge was exacerbated by the storm’s slow movement.
President Donald Trump issued emergency declarations for parts of Louisiana, Mississippi and Alabama on Monday, and urged residents to listen to state and local leaders.

Alabama governor Kay Ivey sought the presidential declaration after the National Weather Service in Mobile, Alabama, warned of the increasing likelihood of “dangerous and potentially historic flooding”, with water rising as much as 9ft above ground in parts of the Mobile area.

Sally achieved hurricane strength on Monday and quickly intensified to a Category 2 storm with 100mph winds, but by Tuesday morning, maximum sustained winds had decreased to 85mph, making it a Category 1 storm, although forecasters say some restrengthening is expected later.
The storm was south-south-east of Biloxi, Mississippi, and east-south-east of the mouth of the Mississippi River, moving at only 2mph.

Forecasters expect the storm to turn northwards on Tuesday afternoon and travel slowly north-north-eastward from Tuesday night through Wednesday. The National Hurricane Centre said early on Tuesday that the centre of the hurricane would be moving near the coast of south-eastern Louisiana later in the day.

Forecasters expect winds to increase to up to 110mph over the warm Gulf waters before the storm blows ashore. On the current track, Sally is forecast to reach land near the Alabama-Mississippi border by late Tuesday or early Wednesday.
