(London Daily Mail) The U.S. Gulf Coast braced Friday for a fast-moving blast of wind, heavy rain and rising water as deadly Tropical Storm Nate threatened to reach hurricane strength before a weekend landfall.

New Orleans Mayor Mitch Landrieu on Friday ordered an evacuation of some areas and a mandatory curfew ahead of Nate.

The curfew will be in effect from Saturday evening to Sunday morning, the mayor said at a news conference.

Alabama, Florida, Louisiana and Mississippi declared states of emergency as the storm twisted toward the U.S. Gulf Coast on Friday after killing at least 22 people in Central America.
