La Nina Has Developed - What It Means for Winter

Posted by Kyle Brookings on Sunday, November 12, 2017

It has been expected for a while and now it has finally happened.

There are weak La Niña conditions now developed in the Pacific Ocean.

La Niña is a ocean-atmosphere phenomenon that is the counterpart of El Niño as part of the broader El Niño–Southern Oscillation climate pattern.

In Canada, La Niña will, in general, cause a cooler, snowier winter, such as the near-record-breaking amounts of snow recorded in La Niña winter of 2007/2008 in Eastern Canada.

This is the second consecutive winter with a weak La Niña.

La Niña is expected to continue through early 2018.
