More than 150,000 people no longer have energy along the Gulf Coast, and thousands were evacuated on the eve of the storm.
Sally̵7;s satellite imagery points to eye reform early Wednesday, another sign of an increase, CNN meteorologist Michael Guy said.
Precipitation of 10 to 20 inches is expected in Mississippi, Alabama and Florida Panhandle, a single amount of 30 inches is possible.
The slow nature of the storm also means that hurricane winds and storm surges will last longer in the area, especially east of the storm center.
Later this week, 6- to 10-inch rains can be seen in Georgia and Carolina as the storm moves inward and subsides.
Delay of large-scale power outages and water repairs
Those on their way to Sally are also experiencing water outages, as the conditions for repairing utilities due to the storm are dangerous.
The Escambia County Public Utilities Department issued a warning on Tuesday that they could not respond to a significant water pipe break on Pensacola Beach due to stormy conditions and the closure of bridges in front of Sally.
The water system had to be shut down at about 11pm as storms and tides would also flood the sewer collection system, according to the ECUA.
“We urge residents who are still on Pensacola Beach to store water if possible. ECUA will send crews to locate the rupture and carry out repairs as soon as possible after the storm,” the statement said.
Closing businesses and military bases restrict access
Businesses are also closing due to the storm, Walmart announced 54 closures due to Sally, Walmart spokesman Scott Pope told CNN on Tuesday.
“We are tracking the storm in real time and have activated our Emergency Operations Center to support our staff in the affected areas,” Pope said.
Across the Gulf Coast, three military facilities have announced that only personnel with a core mission should report for work on Wednesday.
The facilities are the Pensacola Naval Aviation Station in Escambia County, Florida, the Kissler Air Force in Biloxi, Mississippi, and the Eglin Air Force in Pensacola.
Kislar is home to the 53rd Weather Reconnaissance Squadron, often referred to as Hurricane Hunters.
Residents are being evacuated and prepared
Mandatory evacuations have been ordered for most of the coast and lowlands from the Mississippi to Florida. Shelters were opened to accommodate those evacuees.
People have been preparing for Sally over the weekend, filling sandbags, grabbing supplies and preparing their homes.
Merrill Warren of Summerdale, Alabama, about 16 miles from the Gulf, told CNN he brought furniture, purchased gas and other supplies, and prepared the generator for the storm.
On Tuesday night, he reported that heavy rains and winds of up to 39 mph had already hit the land. Warren said he was more concerned about the potential for increased rainfall and splashes than anything else.
“This isn’t the first Category 1 hurricane I’ve been through. I’ve been there through Hurricane Nate and Tropical Storm Gordon,” Warren said. “I’m more worried about the rain for that … problem with a storm moving at 2 mph. “
CNN’s Devon Sayers, Joe Sutton, Sharif Paget, Michael Guy, Dave Hennen, Rebecca Riess, Kay Jones and Amanda Jackson participated in the report.
