Puna Weather
Wednesday 4th March 2026
Today through the upcoming weekend moderate to breezy easterly trade winds with widely scattered showers, mostly during the night and early morning hours.
Surface high pressure to our northeast is driving easterly trade winds through Sunday (surface chart). Upstream moisture is somewhat limited (moisture anomaly chart) and subsidence aloft is keeping our inversion around 5,000' to 7,000' through the period, so rainfall is likely to be less than normal most areas. Some areas from Glenwood to Volcano could benifit from this pattern and see showers continue through the day.
The easterly winds and well defined inversion are likely to keep VOG pushed off to the west.
Our next weather maker is a mid/upper level trough that is forecast to dominate the central Pacific in a week or so. This feature would likely bring colder air aloft creating instability regionally. It would also pull deep tropical moisture over us from the southwest (700-300 hPa moisture chart). This could bring another round of heavy rains, especially from Hilo south.
