With a La Nina advisory in effect, that means we can expect to see several months of La Nina conditions across the Southeast, although the strength of the signal will depend on how strong and how long the La Nina is. Here is a good general discussion on the likely climate effects from Kirk Mellish of WSB in Atlanta, with maps to illustrate the likely climate patterns we can expect to see. Keep in mind that every La Nina is different, but statistically there are some general patterns we can expect across the region.
