Puna Weather
Friday 20th February 2026
Today through Monday mostly light winds with thick clouds and scattered showers, possibly heavy at times. There is a chance for thunderstorms through the period, mostly over our mountains during the afternoons. Onshore winds in the afternoons, which could be briefly gusty near thunderstorms.
The jet stream pushes south and over us for the next week (200mb animation). This pattern brings deep moisture and cold air aloft over our island (500mb chart) with the snow level around 11,000' through the period. The colder air aloft creates instability introducing the risk of heavy rain, but light winds (surface chart) and west flow at our mountain top level means rainfall totals should remain moderate. Winds aloft from west the would push VOG and ash towards the east which could be a risk from Hilo to Kalapana.
