North Atlantic 2020 Tropical Cyclone Season Forecast: Busy season; significant coastal threats.

A dangerous tropical cyclone season is ahead for the North Atlantic basin. A warm North Atlantic coupled with a potential weak La Nina is the recipe for an active season with above average number of hurricanes. Climate Impact Company projects a blocking high pressure over northeastern North America during peak of season which could cause systems near the U.S. East Coast to turn inland.

Strongest Arctic Oscillation on Record

Rare are 3 consecutive months of the same intense polar vortex location during the winter season. However, the lack of displacement of the polar vortex from the North Pole during winter 2019-20 was a leading catalyst to the increased mild maritime influence across most of the continental northern hemisphere causing a record warm winter.

Late Season Cold Snap into Europe

According to the Canadian Ensemble temperature departures from normal are in the -6F to -12F range for much of Europe in the 6-10 day period. Crop areas will receive morning low temperatures in the 20's. The pattern is inspired by the first negative phase North Atlantic oscillation since last November.
