Tropical Storm Activity

Tropical Storm Activity

Tropical storm and hurricane activity in 2020 highlights an expected pattern for La Niña conditions, with suppressed activity in the Pacific, and enhanced activity in the Atlantic. As of the time of this writing, the Eastern North Pacific region has seen 16 named storms (Fig. 1, which does not include Odalys or Polo), which is very close to the average number of named storms, but the accumulated cyclone energy (ACE) is running well behind climatology (Fig. 2). The North Atlantic has recorded a record 30 named storms (Fig. 3, which does not include Eta, Theta, or Iota), which is well above the average of ~10 named storms, and the ACE is running well ahead of climatology as well (Fig. 4).
