The National Hurricane Center in Miami says Hurricane Nate is about 50 miles south of the mouth of the Mississippi River at Louisiana's southeastern tip. The storm is moving north-northwest toward the Gulf Coast at an unusually fast 23 mph (37 kph).

With maximum sustained winds of 90 mph (150 kph), Nate had not gained strength as of the center's 4 p.m. advisory. But forecasters said it might still reach Category 2 strength of 96 mph or more by the time it makes landfall.

Nate was on a track that could take it over or near the mouth of the Mississippi by around 7 p.m. on its way to a later landfall on the Louisiana or Mississippi coast.

Officials in Alabama and Mississippi say their states are starting to see impacts from the fast-approaching Hurricane Nate.

On Alabama's Dauphin Island, Mayor Jeff Collier reports water had already begun washing over the road on the island's low-lying west end.

The city of Gulf Shores, meanwhile, has issued an evacuation order for beachfront properties, and shelters have been opened along the state's coastal counties.

In Mississippi, state Emergency Management Director Lee Smithson said 67 people were already in shelters in two coastal counties while strong winds and high tides were driving Gulf of Mexico waters over roads near the Louisiana state line.

And Gov. Phil Bryant says the state's National Guard has mobilized 75 soldiers and the Highway Patrol has moved an additional 60 state troopers into south Mississippi.

More than 40 percent of manned oil- and gas-producing platforms in the Gulf of Mexico have been evacuated, according to an update from the Interior Department, as Hurricane Nate churns toward the U.S. mainland.

The Department said Saturday that workers were evacuated from 312 of the 737 manned platforms in the Gulf.

Crews also have been taken off 13 of 20 manned drilling rigs and other rigs have been moved out of the storm's path.

About one-fifth of U.S. oil is produced in the Gulf. The platforms mostly avoided Hurricane Harvey in late August.

Nate is speeding north-northwest over the Gulf of Mexico. Forecasters say the hurricane is expected to make landfall Saturday night along the central U.S. Gulf Coast — likely with Category 2 strength.

Governors in Louisiana and Florida are urging residents to make final preparations for Hurricane Nate's impending arrival.

In Louisiana, Gov. John Bel Edwards said Saturday that people in the southeastern part of the state should hunker down by 3 p.m.

He says the storm's eye is expected to make landfall about four hours later, likely bringing limited rain but powerful storm surges and strong winds.

The state National Guard, meanwhile, has mobilized 1,300 troops and positioned high-water vehicles, boats and even school buses from Baton Rouge to New Orleans to help with rescues.

Edwards said he also spoke with President Trump Saturday morning, who assured him the federal government was prepared to respond as well.

In Florida, Gov. Rick Scott said the roughly 100,000 residents in evacuation zones should heed warnings, stick to their emergency plan and stay vigilant for updates from local officials.

He said the hurricane could bring not just storm surges and strong winds to the Panhandle, but also tornadoes.

Early voting is wrapping up sooner than scheduled in parts of Louisiana because of Hurricane Nate.

Meg Casper Sunstrom, spokeswoman for the Secretary of State's office, said voters in some southeastern parishes will have until 3 p.m. on Saturday to cast their ballots early.

The parishes affected are in the New Orleans-area, including Orleans, St. Bernard, Plaquemines and St. Tammany parishes.

Early voting will continue to close at 6 p.m. in the state's other parishes.

Saturday is the last day of the week-long early voting period. Louisiana has a statewide election Oct. 14, and New Orleans has a hotly contested mayor's race on the ballot.

The National Weather Service is placing much of Alabama under a tropical storm warning.

Forecasters said Saturday that Hurricane Nate could bring wind gusts of up to 60 mph (95 kph) across much of the central part of the state, which includes Birmingham, the state's largest city.

The storm is expected to down trees and cause significant power outages. Isolated tornadoes were also possible Sunday afternoon.

On Alabama's Gulf coast, some communities have already imposed mandatory curfews from Saturday evening through Sunday morning. They've also ordered beaches and fishing piers closed and issued voluntary evacuation orders.

On Florida's Panhandle, officials have ordered evacuations in some low-lying areas. They're also warning beachgoers to stay out of the Gulf of Mexico as the storm is already whipping up deadly rip currents and rough surf.

Flood-prone underpasses in New Orleans will be blocked to traffic in anticipation of possible heavy rain from Hurricane Nate.

Mayor Mitch Landrieu made the announcement Saturday as Nate was moving swiftly toward the northern Gulf Coast.

Motorists who stall their cars while trying to drive through high water at the underpasses are a recurring problem during heavy rains. The move to block access to underpasses comes as the city works to fix recently revealed weaknesses in its drainage system.

Nate was on a forecast track taking it past Louisiana's southeast tip by around 7 p.m., heading for an expected Mississippi landfall.

Among precautions in Mississippi: transportation officials say highway crews are lowering the high masts that hold street lights to keep the lights from becoming projectiles in expected high winds.
