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.
