As far back as August 2010, NOAA's seasonal climate models predicted that rainfall would be heavier than normal across Indonesia and Southeast Asia in early 2011. The cause? La Niña.

Large-scale shifting of the weight of the atmosphere between mid- and high latitudes creates climate patterns known as the Arctic and North Atlantic Oscillations. These patterns have a big influence on winter weather in the Eastern U.S.

Weather in the Southeast this fall and winter is keeping up with the dry part of the typical La Niña pattern. Precipitation across most of the Southeast was "below" or "much below" normal for October-December.
