Puna Weather
Thursday 27th August 2026
Today through Tuesday light to moderate easterly trade winds and widely scattered showers.
High pressure to our northeast looks to maintain typical trade winds over us through Tuesday. By Wednesday humidity spikes as the remnant moisture from ex-Iselle arrives.
All eyes are on the tropics today as we have a new topical low trying to form near 11N 135W. Low level westerlies have appeared on the south side of the circulation and that may be sufficient for the NHC to upgrade to a Tropical Depression soon. This is the same region that spawned Lala and Moke. 94E has deep convection firing very near the apparant center of circulation. This is something that Lala and Moke struggled with initially, and may allow 94E to consolidate more quickly than the others did.
Ex-Iselle is creating a weakness in the subtropical ridge and 94E is forecast to move towards that weakness, to the northeast, for the short term. As ex-Iselle weakens and moves west embedded in the low level trade flow, and so does 94E with some runs of the GFS and the ECMWF bringing the storm dangerously close to our island in a week or two.
Data from the Copernicus project indicates that we've reached a new high temperature for sea surface temperatures averaged globally from 60N to 60S. That warm water is a stand out feature for our basin as El Nino is in full swing and waters to our south and east running well above normal for this time of year. Because of this we're seeing back to back tropical threats. It looks like it's going to be a long hurricane season.
