WMO officially calls a La Nina winter

Reading Time: 2 minutes MarketsFarm — A La Nina weather event has officially developed in the Pacific Ocean and is expected to continue into 2021, affecting temperatures, precipitation and storm patterns around the world, according to the World Meteorological Organization (WMO). The global declaration of the La Nina event by the United Nations’ agency will be used by governments […] Read more

La Nina to bring colder, drier winter

Reading Time: 2 minutes MarketsFarm — There’s a La Nina poised to exert influence on the coming North American winter, according to Drew Lerner, senior agricultural meteorologist for World Weather Inc. in Kansas. A La Nina generates colder-than-normal temperatures, as opposed to the warm temperatures garnered from an El Nino. Both weather phenomenon can be found over the Pacific […] Read more

La Nina present, 75 per cent chance seen through 2020 winter

Reading Time: < 1 minute Reuters — La Nina conditions were present in August, and have a 75 per cent chance of continuing through the Northern Hemisphere winter of 2020-21, a U.S. government weather forecaster said on Thursday. The La Nina pattern is characterized by unusually cold temperatures in the equatorial Pacific Ocean. A borderline moderate La Nina event is […] Read more

U.S. forecaster says La Nina expected to develop in fall 2020

Reading Time: < 1 minute Reuters — A U.S. government weather forecaster on Thursday forecast the development of a La Nina pattern during the August-October season, which is expected to persist through the remainder of 2020. There is about 50-55 per cent chance of La Nina developing during the Northern Hemisphere fall, with a 50 per cent chance it will […] Read more

El Nino, La Nina patterns not seen prevailing during summer

Reading Time: < 1 minute London | Reuters — Sea surface temperatures in the tropical Pacific remain neutral, meaning that neither El Niño nor La Niña weather patterns are prevailing, the U.N. World Meteorological Organisation said on Thursday. The El Niño pattern brings a warming of ocean surface temperatures in the eastern and central Pacific every few years, and is […] Read more

U.S. forecaster sees 65 per cent chance of no spring El Nino, La Nina

Reading Time: < 1 minute Reuters — There is about a 65 per cent chance that neutral weather conditions will prevail in the Northern Hemisphere this spring with no El Niño or La Niña, up from 60 per cent last month, a U.S. government weather forecaster said on Thursday. The El Niño-Southern Oscillation-neutral (ENSO) weather pattern is marked by average […] Read more

El Nino likely not responsible for warm, dry conditions

Reading Time: 2 minutes CNS Canada — The above-normal temperatures Western Canada has generally experienced since the fall weren’t necessarily caused by an El Nino. Rather, to Agriculture and Agri-Food Canada, the phenomenon that’s likely affected the weather was a ‘blob’ that formed off of the coast of British Columbia. “It’s a big warm pocket of ocean water and […] Read more

U.S. forecaster sees 90 per cent chance of El Nino in winter

Reading Time: < 1 minute Reuters — There is a 90 per cent chance of the El Nino weather pattern emerging during the Northern Hemisphere winter of 2018-19, a U.S. government weather forecaster said on Thursday. “The official forecast favours the formation of a weak El Nino,” the National Weather Service’s Climate Prediction Center (CPC) said in a monthly forecast.

La Nina seen likely to fade by spring

Reading Time: < 1 minute Reuters — The current La Nina weather cycle is likely to transition into more neutral conditions by spring, a U.S. government weather forecaster said Thursday. La Nina is characterized by unusually cold ocean temperatures in the equatorial Pacific Ocean and is linked with floods and droughts. It is the opposite phase of what is known […] Read more

U.S. forecaster says La Nina faded, sees El Nino potential

Reading Time: < 1 minute Reuters — A U.S. weather forecaster on Thursday said La Nina has faded and neutral conditions are likely to continue in the coming months, though it noted some chance that the El Nino phenomenon may reappear as early as the Northern Hemisphere spring. The Climate Prediction Center (CPC), an agency of the National Weather Service, […] Read more
