The 2018-19 Alaskan arctic cyclone season will begin on October 1, 2018 and end on April 1, 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, which typically limits polar cyclone formation, this season is expected to be below-average in terms of activity.
