Example Input: NEW ORLEANS (Reuters) -  Hurricane Nate  made landfall near the mouth of the Mississippi River as a Category 1 storm with winds of 85 miles per hour on Saturday evening  threatening parts of Louisiana  Mississippi and Alabama with torrential rain and potential flooding.
Nate  the fourth major storm to strike the United States in less than two months  killed at least 30 people in Central America before entering the warm waters of the Gulf and bearing down on the U.S. South.
As the hurricane struck at about 7 p.m. CDT (0000 GMT Sunday)  the National Hurricane Center (NHC) downgraded its warning for New Orleans to a tropical storm. But  Nate  was expected to regain some strength and make a second landfall along the coast of Mississippi to the east.

 Nate  comes on the heels of three other major storms  Harvey  Irma and Maria  which devastated Texas  Florida and Puerto Rico  respectively. But as a Category 1  the weakest in the five-category ranking used by meteorologists   Nate  appeared to lack the devastating punch of its predecessors.

Major shipping ports across the central U.S. Gulf Coast were closed to inbound and outbound traffic on Saturday  as  Nate  intensified and storm surges of up 11 feet (3.74 m) were expected at the mouth of the Mississippi River.
Before heading north into the Gulf   Nate  brushed Mexicoâs Yucatan peninsula  home to beach resorts such as Cancun and Playa del Carmen  the NHC said.

Example Input: Ever since early 2016 , when the Republican Party began to fussily resettle itself behind Donald Trump , Mitt Romney has been an intermittent oppositional figure , distinct from his party in both point of view and style . 
The conservative movement has grown smirking , clannish , quarrelsome ; Romney has been formal , chiding , and pained . 
After Trump won the election , that November , Romney met with Trump in the hope of securing for himself the position of Secretary of State . 
Yet this summer , after a white-supremacist rally in Charlottesville turned deadly , Romney professed deeper anxieties . 
For half a century , Romney and his family have existed close to the center of the Republican Party . 
Now -- just six years removed from being his party 's Presidential nominee , but with no distinct Romneyist camp in Washington and no obvious constituency to summon -- it is n't obvious that Romney fits in at all . 
Last week , the Utah senator Orrin Hatch announced that he would be retiring at the end of his term this year , and immediately Romney 's allies suggested that he would run for the seat ; the common wisdom was that his election would be all but assured . 
-LRB- Romney , a man of many residences , built his political career in Massachusetts , but he went to college in Utah , and helped to save the Salt Lake City Olympics from ruin in 2002 ; he is the most recognizable Mormon in the world , and he would be running in a state whose Republican Party is defined by its relationship to the L.D.S. Church . -RRB- 
Romney 's candidacy is still unannounced , and its most important position -- what line the candidate takes on the President -- is not yet obvious . 
"This thing is still developing ," one of Romney 's longtime advisers told me last week . 
But already the most romantic vision of Romney -- that he might arrive in Washington as the de-facto leader of an anti-Trump faction -- seems unlikely . 
"I 've heard some relatively simplistic assessments that he is going to be the voice of the Never Trump movement ," a senior adviser to Romney 's Presidential campaign said last week . 
Romney is a very pragmatic politician , too . 
Romney himself has made no sign of wanting to be part of such a faction , even if it existed . 
One of his advisers reminded me last week that Romney took the idea of being Trump 's Secretary of State seriously , and believed that Trump 's interest in him was entirely sincere . 
And , a month after his appalled reaction to Charlottesville , Romney tweeted praise for Trump 's speech before the U.N. General Assembly . 
Romney 's potential for tragedy and heroism both spring from the same source : the depth of his feeling for a version of America that may exist only in his mind , a place where the trees in Michigan are exactly the right height . 
Romney 's return to Utah has some elements of a homecoming ; it is also , more simply , a move to accommodating political terrain . 
Utah is a conservative state whose politics are moving toward Romney , rather than away . 
Modern Utah , the place of the salvaged Salt Lake Olympics , exists in the Romney image .

Example Input: Within the last month   Mayor Rahm Emanuel  has been heckled on out-of-town campuses on the West Coast and in the Midwest about  his  plans for a new police academy. Now it looks as if  he âll add an East Coast Ivy League academy into the mix.
The letter â which complains that the $95 million being spent on a new police academy would be better spent on schools â echoes comments directed at  Emanuel  by handfuls of hecklers at the University of Michigan in Ann Arbor on Jan. 19  and at the University of California  Los Angeles  on Feb. 12.
In Los Angeles last week   Emanuel  laughed off the protests  telling  his  audience that  he  âdidnât realize there were that many direct flightsâ from Chicago. In Ann Arbor   Emanuel  attempted to engage the protesters  who continued to chant at  him . Some in the audience booed the hecklers.
But the Harvard protesters accuse  Emanuel  of doing too little to halt the decline in the size of Chicagoâs black population and write that  âAs future and current designers  urban planners  policy-makers  organizers and educators  we cannot disregard the people who are in danger because of Rahm Emanuelâs administration.â
