Reuters — La Nina conditions are likely to continue during the Northern Hemisphere spring, a U.S. government weather forecaster said on Thursday.
The La Niña weather pattern, characterized by unusually cold temperatures in the equatorial Pacific Ocean, has a 67 per cent chance of persisting from March through May this year, the National Weather Service’s Climate Prediction Center (CPC) said.
The CPC, in its monthly forecast, estimated a 51 per cent chance of a transition to El Nino-Southern Oscillation (ENSO)-neutral conditions during the April-June period.

Manitoba and Saskatchewan can expect cold temperatures to settle in. Alberta will benefit from some moderating influences, with colder temperatures not expected to last long.
ENSO-neutral conditions refer to periods in which neither El Niño nor La Niña is present, often coinciding with the transition between the two weather patterns, according to the center.
The El Niño pattern brings a warming of ocean surface temperatures in the eastern and central Pacific every few years, and is the opposite of La Niña.
Earlier this week, Japan’s weather bureau said the La Nina phenomenon is continuing and that there is an 80 per cent chance it will prevail through the end of the Northern Hemisphere winter and an 80 per cent chance the conditions will end in spring.
