 Hurricane Nate  rolled into the mouth of the Mississippi River on Saturday night as a Category 1 storm with maximum sustained winds of 85 mph  the National Hurricane Center reported with predictions it would quickly begin to lose strength.
The storm made landfall about 10 miles southwest of the Mississippi River's mouth or about 100 miles south of Biloxi. Forecasters said while wind speeds had dropped   Nate  still would bring the potential for heavy storm surges  depending on how the winds and tides combined.
Forecasters initially had predicted  Nate  would gain strength but new data shows the storm's maximum winds dropped to 85 mph.

"Strengthening now appears unlikely before  Nate 's center reaches the Mississippi coast during the next few hours " the hurricane center reported. "Rapid weakening is expected after landfall with  Nate  becoming a tropical depression by Sunday night" when its center is forecast to be over the Knoxville area and Smoky Mountains in Tennessee.
The center predicted  Nate  would turn toward the north-northeast Saturday night  then northeast. The center of  Nate  is expected to make a second landfall along the coast of Mississippi tonight.
States of emergency were declared in four Gulf Coast states as Nate  which already killed at least 21 people in Central America  became the latest in a succession of destructive storms this hurricane season.
President Trump approved an emergency declaration for a large area of the state and ordered federal assistance for Louisiana as  Nate  approached the central Gulf of Mexico.
âWe are ready for whatever  Nate  brings our way â Landrieu said. Two flash floods this summer led to revelations about personnel and equipment problems at the agency that runs that system.
â¢ In Mississippi  Gov. Phil Bryant declared a state of emergency in six southernmost counties. State officials warned that  Nate âs main danger was the possibility of up to 10 feet of storm surge in low-lying coastal areas as well as from winds that could damage mobile homes.
He warned people to be prepared to be self-sufficient for at least 72 hours. A 7 p.m. to 7 a.m. curfew was ordered for Jackson County just east of Biloxi  where the brunt of  Nate  was expected.

Russian election officials on Monday formally barred  Russian opposition leader Alexei Navalny  from running for president  prompting calls from  him  for a boycott of next year's vote.
 Navalny  is implicitly barred from running for office because of a conviction in a fraud case which has been viewed as political retribution.  He  could have run if  he  was given a special dispensation or if  his  conviction was cancelled.
 Incumbent Vladimir Putin  is set to easily win a fourth term in office in the March 18 election  with  his  approval ratings topping 80%.
 Putin  foe clears first step in bid for Russian presidency
Over the past year   Navalny  has mounted a grassroots campaign which reached out to the most remote corners of  Putin 's heartland.
 Navalny   41  is the most serious challenger that  Putin  has faced in all  his  years in power  and the court cases against  him  have been widely seen as a tool to keep  him  from running for office.
In a pre-recorded video message that was released minutes after the Election Commission handed down the decision  Navalny called on  his  supporters to boycott the vote.
"The procedure that we're invited to take part is not an election "  he  said. "Only Putin and the candidates  he  has hand-picked are taking part in it."
Central Election Commission chief Ella Pamfilova told  Navalny  ahead of its vote to bar him that "maybe we would be interested if you were running " but said the conviction doesn't allow the commission to put him on the ballot.
Speaking before the vote   Navalny  told the commission that  their  decision to bar him would be a vote "not against me  but against 16 000 people who have nominated me  against 200 000 volunteers who have been canvassing for me."
The involvement of Ksenia Sobchak  a 36-year-old star TV host  could raise public interest in the race. While Sobchak has denied colluding with the Kremlin  she could attract some of  Navalny 's supporters and help boost attendance.
Sobchak criticized  Navalny 's call for boycotting the vote  saying Monday that the "election is the only way to change something  and boycotting them is inefficient and harmful."

The closest  Mark Zuckerberg  has come to directly addressing President Donald Trump in public was when  he  wrote that "progress does not move in a straight line" the day after the election in November.
Since then   Zuckerberg  has embarked on  his  own tour of the U.S. that's been compared to a presidential campaign and sparked rumors that the Facebook CEO is considering a 2020 run.
While  Zuckerberg  has been shy to publicly address Trump   he  has in fact spoken with the president multiple times by phone since the election  Business Insider has learned.  Zuckerberg  revealed that  he 's talked with Trump during a surprise dinner with the Moore family in Newton  Ohio two weeks ago.
Exactly what  Zuckerberg  and Trump discussed is unclear —  Zuckerberg  didn't say during  his  dinner with the Ohio family and  his  spokesperson declined to comment. But the discussions show that the Facebook billionaire has held a dialogue with Trump even as  he  publicly opposes policies like Trump's first executive order on immigration. The White House didn't return a request for comment.
 Zuckerberg  and Facebook's relationship with Trump is complicated. Facebook was widely criticized in the wake of the election for its role in the proliferation of so-called fake news  which many believed help Trump win the election.  Zuckerberg  has called that notion "pretty crazy " but Facebook has made significant strides to eradicate fake news stories from its platform.
When Trump called together the tech industry's top leaders for a meeting of the minds in December  Facebook COO Sheryl Sandberg went instead of  Zuckerberg . Before Trump was elected   Zuckerberg  had come to the defense of the Facebook board member and Trump advisor who organized that same meeting with tech leaders  Peter Thiel.
"We care deeply about diversity "  Zuckerberg  wrote in an internal memo to Facebook employees that was leaked in October. "That's easy to say when it means standing up for ideas you agree with. It's a lot harder when it means standing up for the rights of people with different viewpoints to say what they care about. That's even more important."
