2020-21 North Pacific winter windstorm season

The 2020-21 North Pacific winter windstorm season runs from October 1 to March 31.

Tables

Aleutian – Large, strong, deep, and consolidated cyclone reaching peak intensity near the Aleutian islands
Aleutian b "Siberian Slush" – Weaker satellite cyclone associated with a large and broad push of cold Siberian air
Aleutian c – Cyclone that develops in the Aleutian/Bering region as a result of cold advection from a cyclone downstream of it
Kona – cut-off low near Hawaii
Northwesterly (kNW) – Cyclones associated with a northwesterly jet tracking toward the southeast, particularly into the western United States, with a ridge upstream
Fast Elongated Weak (FEW) – storms that are typically east-west elongated, weak and often deepening as they exit Japan into the open north Pacific, travelling quickly east or northeast and lasting less than a day, usually are followed by a strong cyclone which usually forms either behind or peripherally on the surface low (but is a different system)
