The National Hurricane Center has extended hurricane wind and surge warnings east in the 10 p.m. Sunday update
"Reports from the aircraft indicate that the center of Sally has jogged to the northeast," said Senior Hurricane Specialist John Cangialosi.

Cangialosi syas the hurricane center is moving the forecat track for Sally a little further east, based on expected changes in steering currents in the atmosphere.
"The global models show a trough exiting the northeast U.S. tomorrow and a ridge building to the north of Sally, which should cause the storm to resume a west-northwest motion at a relatively slow pace on Monday," he explained. "By Monday night and Tuesday, the ridge is forecast to slide southeastward as another trough develops over the south-central U.S. This change in the pattern should cause Sally to slow down even more and gradually turn to the north and then the northeast."
With the current forecast showing a landfall near Bay St. Louis, authorities in Hancock County, Mississippi have issued a mandatory evacuation for low-lying areas, residents along rivers, creeks, and bayous, and residents in trailers, mobile homes, and modular homes.

Cangiolosi said the eastward shift in their forecast necessitated issuing extending the hurricane warning to the Alabama/Mississippi line, and extending the storm surge warning east to the Alabama/Florida line, including Mobile Bay.
All watches and warnings remain in effect for southeastern Louisiana as well.
