Puna Weather
Monday 24th August 2026
Today warm and humid with scattered showers and light southeast winds. VOG is possible.
Tuesday a little less humid with scattered showers and light moderate easterly trade winds.
Wednesday through Sunday much less humid (hopefully) with scattered showers and light moderate easterly trade winds.
As Tropical Depression Moke exits to our west it drags a tail of tropical moisture over us today into early Tuesday.
Fairly typical trade winds return along with less humid air heading into Wednesday.
Far to our east is Tropical Storm Iselle, which is forecast to become a hurricane soon. Iselle formed pretty far north and is now on a track towards the northwest where there is mid-level dry air and colder sea surface temperatures. This will cause the storm to weaken significantly. Once the storm is just a remnant low, it'll be guided by the low level trade flow and be steered west. The most recent model runs keep Iselle's moisture north of us, but close enough to not be sure.
The latest MJO report came out today and says the MJO is weak compared to the impacts from the El Nino, which has been keeping our region quite active recently. The report also states that higher than normal shear nearer the coast of Mexico has been promoting cyclone genesis farther west than is typical. Almost on cue, the GFS wants to spin up another trouble maker in a just few days over the same place that spawned Lala and Moke.
I guess we're once again watching the tropics. Sorry about the back to back threats.
