Classical La Nina pattern, which is bringing severe storms, floods, and landslides above northern countries of South America (Colombia, Venezuela, Guyana region, or northern Amazon, Brazil, and Ecuador) was in Summer 2022 in Southern Hemisphere (DJF) affected by the strong shift of a season of rains southward, above central parts fo the continent, while Colombia or Venezuela reported during the peak of the season (January) regionally very dry conditions.
Although local floods and landslides were in the last period still reported, e.g. 15 dead, 34 injured, 2 missing following a landslide caused by heavy rainfall near Pereira, Risaralda, large parts of Colombian and Venezuelan Amazon were destroyed by extensive wildfires.
E.g. in Colombia according to /https://twitter.com/globalforests/status/1492136558979395587/photo/1/, in January 2022, 1800 wildfires in Amazon appeared, while before a year, in January 2021, during strong La Nina it was only 65 wildfires.
It should be a sign of a weakening La Nina when during the weaker pattern, the season of rains is shifted more southward, or storms in the region aren´t so severe.
Extreme floods however in January were reported from parts of Brazil, Ecuador, or Peru /e.g. https://mkweather.com/floods-in-ecuador-quito-brazil-sao-paulo-peru-machu-picchu-and-colombia-tolima-minimally-50-dead/; https://mkweather.com/floods-in-ecuador-quito-brazil-sao-paulo-peru-machu-picchu-and-colombia-tolima-minimally-50-dead//.
Wildfires even hit a region very close to the Colombian capital, Bogota.
In the previous week, an environmental alert has been issued in the Colombian capital, Bogota, threatened by smoke from active forest fires affecting an area the size of Paris in the country’s Amazon region. /https://respromasks.com/2022/02/07/forest-fires-in-amazonian-region-trigger-environmental-alert-in-colombias-capital//.
At the same time, due to the fires, around 600 municipalities were on varying phases of alert, 550 on red alert – the highest level.
According to forecasts for March, April, May, June, July, and August 2022 (maps below), severe storms are forecast to return from central parts of the continent to the north, but La Nina will be still weakening and in the next season, extensive wildfires should thank El Nino be repeating.
Dry El Nino is predicted to come already around Autumn 2022 /https://mkweather.com/el-nino-is-coming-autumn-2022-a-big-changes-in-circulation-patterns-worldwide//.
