El Nino to continue through Northern Hemisphere spring, U.S. forecaster says

Reuters — El Nino weather conditions will continue through the Northern Hemisphere during April-June 2024 with a 62 per cent chance, a U.S. government weather forecaster said on Thursday. “Above-average sea surface temperatures (SST) across the equatorial Pacific Ocean were indicative of a strong El Nino, with anomalies increasing in the central and east-central Pacific […] Read more

World could face record temperatures in 2023 as El Nino returns

New record highs 'more likely than not'

Brussels | Reuters — The world could breach a new average temperature record in 2023 or 2024, fuelled by climate change and the anticipated return of the El Nino weather phenomenon, climate scientists say. Climate models suggest that after three years of the La Nina weather pattern in the Pacific Ocean, which generally lowers global […] Read more

U.S. forecaster sees 62 per cent chance of El Nino developing during May-July

Argentina, parts of U.S. could benefit; Asian crops may not

Reuters — A U.S. weather forecaster on Thursday predicted a 62 per cent chance of the El Niño phenomenon developing in the Northern Hemisphere during May-July, and a strong chance toward end-year, likely compounding risks to crops across the globe. “The coastal warming in the eastern Pacific may foreshadow changes across the Pacific basin. Therefore, […] Read more

La Nina conditions to continue, but odds lower into winter

Reuters — Chances for La Niña are expected to gradually decrease from 86 per cent in the coming season to 60 per cent during December to February in 2022-23, a U.S. government weather forecaster said on Thursday. The La Niña weather pattern is characterized by unusually cold temperatures in the equatorial Pacific Ocean. According to […] Read more

La Niña likely to continue into spring, U.S. forecaster says

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 […] Read more

Another La Nina winter predicted

Polar vortex to chill Prairies, more snow further east, AccuWeather says

Data compiled by a U.S. federal weather forecasting agency show La Nina conditions have developed over the central Pacific Ocean and are likely to linger through February. And La Nina, in turn, is expected to produce hard cold snaps over the Prairies, above-normal precipitation over southern British Columbia and relatively mild temperatures with more snow […] Read more

La Nina done, U.S. CPC says

Neutral weather likely through summer

Reuters — A U.S. government weather forecaster said on Thursday La Nina has ended and El Nino-Southern Oscillation (ENSO) neutral conditions are likely to continue through the Northern Hemisphere summer. “ENSO neutral” refers to periods in which neither El Nino nor La Nina is present, often coinciding with the transition between the two weather patterns, […] Read more

WMO officially calls a La Nina winter

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

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

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
