The La Niña of 2016 is now officially gone. Following on from a monster El Niño, it turned out to be one of the shortest and weakest on record.
La Niña, which can influence weather across many parts of the world, is characterized by abnormally cool surface waters in the central equatorial Pacific Ocean. Those have now mostly dissipated, leaving behind temperatures that are close to average for February. Forecasters expect these neutral conditions to continue for the next few months.
