Puna Weather
Saturday 5th September 2026
Today light winds and scattered showers. VOG is possible.
Sunday through Tuesday very humid with moderate southerly winds and periods of heavy rain possible. VOG is possible.
Wednesday decreasing humidity through the day with moderate easterly trade winds and scattered windward showers.
Lowell didn't make it to annular, but remains a powerful storm with top sustained winds of around 150mph. Lowell could see a final spell of strengthening between now and Sunday at which time shear from the southwest will lead to steady weakening at the storm is carried north by an upper level trough, the same one that's creating the southwest shear (200mb chart).
All models show Lowell passing a safe distance to the west of Kauai.
As Lowell moves north of our island chain, it merges with Karina and the combo storm pulls deep tropical moisture up from the south and over our island for very humid conditions. Winds will be from the south, which would typically favor Kau, south Puna, and Fern Acres/Volcano. But moisture is near or above 2" PW the entire period, so hit and miss heavy rain is possible everywhere.
The moisture tap finally moves west of us Wednesday with lower humidity through next Saturday. More tropical could be moving into the region next weekend on mid-level southeasterly flow. The GFS has stopped showing a tropical low forming, just a bunch of moisture.
