La Niña Expected to Develop - What That Could Mean for Winter

Posted by Kyle Brookings on Saturday, October 14, 2017

According to the latest outlook from NOAA, weak La Niña conditions expected to develop by this winter.

There is a 55 to 65 percent chance.

La Niña is the positive phase of the El Niño Southern Oscillation and is associated with cooler-than-average sea surface temperatures in the central and eastern tropical Pacific Ocean.

A La Niña Watch is in effect. This watch is issued when conditions are favorable for the development of La Niña conditions within the next six months.

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.
