WASHINGTON – La Nina, the cooler and at times costlier flip side of El Nino, has arrived to warp weather worldwide, meteorologists said Thursday. This natural weather phenomenon often turbocharges the Atlantic hurricane season, but this La Nina may be too weak and fleeting to cause much trouble.

In the United States, La Nina often means more precipitation — including possible snowstorms — in northern areas and winter dryness in the South. It can bring heavier rains in Indonesia, the Philippines, parts of Australia, Central America, northern South America and southeastern Africa. It also can mean drought in the Middle East, eastern Argentina, eastern China, Korea and southern Japan, meteorologists said.
