Which reminds me - the Australian counterpart still has not declared that El Nino is here as of this fortnight even though the SOI is negative, the ocean has surpassed El Nino conditions and that they say there's a 70% chance of El Nino developing soon (El Nino Alert). Sounds like they're relying on climatology that's more recent compared to the old one (1991-2020 vs 1979-1998).

They say that the Tahiti pressure is close to average while the Darwin pressure is contributing to the El Nino like SOI.

Do you factor those two pressure systems when making the declaration of El Nino or La Nina on your side? Just curious whether if this needs to be looked at for future El Nino/La Nina declarations down the road.
