Puna Weather
Tuesday 18th August 2026
Today and Wednesday moderate easterly trade winds with widely scattered showers.
Thursday humid with scattered showers and light winds. VOG is possible.
Friday and Saturday humid with scattered showers and moderate easterly trade winds.
There are 3 areas of interest to me in the tropics over the next week. Referring to the charts all the labeled areas are over very warm sea surfaces temperatures.
A is forecast to form under divergent flow in the upper levels at a very south location, and as such all models take this feature well to our south posing no risk to us.
B is a phantom of the GFS being over enthusiastic about high moisture and should probably be ignored.
C doesn't form for a week and it forms in an odd location 130W. I'm skeptical due to the long lead time, nonetheless this is the one that has my attention.
