2018-19 Alaskan Arctic Cyclone Season

The 2018-19 Alaskan arctic cyclone season will begin on September 15, 2018 and end on March 15, 2019. However, polar cyclone formation is possible at any time in the year. Due to an expected El Niño which flatlines the jet stream over the basin, activity will likely be more limited in this season.
