Puna Weather
Monday 2nd November 2026
Tonight decreasing humidity with widely scattered showers.
Monday through Thursday less humid with light to moderate east or northeast trade winds and occasional showers, mostly during the night and early morning hours.
A ridge of high pressure to our north builds over the next few days keeping mostly easterly trade winds over us through Thursday. Upstream moisture looks drier with dew points in the mid-60s for much of the period.
In the tropics I'm watching an area of warm sea surface temperatures and forecasted low shear to our southeast where a tropical low could form over the next week. If a low forms, its track is uncertain due to interactions with two upper level troughs that swep across the north Pacific, each possibly stalling or adding a northward component to the low. We'll have a better idea of the risks to our island when a low actually forms. On the storm's path west shear is forecast to be low, but there's been unforecast easterly shear with previous storms in this location, so I remain skeptical.
This year all these potential risks have to be taken seriously because the waters are so warm off our coasts that storms could strengthen quickly when all the ingredients come together.
