La Niña is occurring in the Pacific Ocean this year, but what exactly does that mean?
It’s a low-pressure system that is creating cooler than average temperatures in the ocean. This temperature change means the cooler winter weather will stay up north in parts of Canada, while the southern U.S., including Louisiana, will experience warmer than average temperatures this winter.
While this may not come as a shock to New Orleanians, one benefit of La Niña is it provides drier air than normal, so we can expect fewer winter showers. The projections match up closely with last year.
