Puna Weather
Thursday 5th March 2026
Today through Sunday moderate easterly trade winds with widely scattered showers, mostly during the night and early mornings.
Monday and Tuesday moderate to breezy southeast winds with widely scattered showers.
High pressure to our northeast supports trade winds out of the east through Sunday (surface chart).
Early next week a jet stream trough forms to our northwest (200mb chart). The trough deepens mid-week and is forecast to be long lived. This pattern pulls tropical moisture over us from the southwest (700-300hPa moiusture) with winds near the surface out of the south. It also brings colder air aloft for heavier rain. Additional factors include surface winds and divergence... the details will become clearer as time goes on. Both the GFS and the ECMWF models are showing this trough and an associated long period of rainy weather beginning in a week.
