The expected onset of positive phase Indian ocean Dipole by JUL/AUG 2023 is delayed. The issue is the vertical motion in the tropical Indian/Pacific Ocean(s) is not well-correlated with an El Nino climate which would drive +IOD evolution. Until the El Nino climate pattern develops (AUG/SEP), +IOD will be delayed and the longer the delay the more likely +IOD is not as strong as currently forecast by most dynamic models.

Due to a delayed atmospheric El Nino and record warm North Atlantic, the North Atlantic basin seasonal forecast is revised. The updated forecast projects 20 tropical storms, 9 hurricanes, and 4 intense hurricanes. Previously, only 3 seasons have produced 20 (or more) tropical cyclones. If 2023 observes 20 tropical cyclones, 3 of the past 4 years will have managed that achievement.
