- The National Hurricane Center expected Sally to remain a Category 1 hurricane when it comes ashore, adding "historic life-threatening flash flooding is likely."
- The forecast map showed the center likely coming ashore in Alabama, near the Florida line.
- Forecasters warned that Sally could unleash flooding similar to what Hurricane Harvey inflicted in 2017 in swamping the Houston metropolitan area.
Heavy rain, pounding surf and flash floods hit parts of the Florida Panhandle and the Alabama coast on Tuesday as Hurricane Sally lumbered toward land at a painfully slow pace, threatening as much as 30 inches (76 centimeters) of rain and dangerous, historic flooding.
The storm's center churned offshore 65 miles (105 kilometers) south-southeast of Mobile, Alabama, as Sally crept north-northeast toward an expected Wednesday landfall at 2 mph (3 kph), according to the National Hurricane Center. The forecast map showed the center likely coming ashore in Alabama, near the Florida line.

Up to a foot (more than 30 centimeters) of rain had fallen already on the coast by Tuesday night and Sally's lumbering pace meant there would likely be extended deluges.
"A hurricane moving at 2 mph is stalled for all intents and purposes," said Brian McNoldy, a hurricane researcher at the University of Miami. "If they aren't moving along and they just kind of sit there, you're going to get a ridiculous amount of rain."
Sally strengthened a bit late Tuesday, with sustained winds reaching 85 mph (140 kph).

In Orange Beach, Alabama, towering waves crashed onshore as Crystal Smith and her young daughter, Taylor, watched before nightfall. They drove more than an hour to take in the sight.

Capt. Michael Thomas, an Orange Beach fishing guide, secured boats and made other last-minute preparations. He estimated up to 5 inches (13 centimeters) of rain had fallen in as many hours.
"I'm as prepared as I can be," Thomas said.
Stacy Stewart, a hurricane center senior specialist, warned that floods could be deadly.
"This is going to be historic flooding along with the historic rainfall," Stewart said. "If people live near rivers, small streams and creeks, they need to evacuate and go somewhere else."
