Puna Weather
Friday 10th April 2026
This afternoon and tonight humid with VOG and tepra possible from Volcano to Hilo. Winds moderate from the southeast with occasional periods of heavy rain.
Friday frequent heavy rain and thunderstorms some of which could be very strong. Moderate to breezy south or southeast winds. Widespread flooding is possible.
Saturday and early Sunday scattered showers with light winds and afternoon thunderstorms, especially over higher terrain. Possible VOG.
A massive trough to our west (satellite animation) is pulling moisture up from the tropics and over us. As it inches towards us a couplet of upper level diverging winds and lower level converging winds passes over us (chart). This combination causes air to rise from the surface to fill the space provided by the diverging winds higher in the atmosphere. With deep moisture in place and this tendency for the air to rise, expect a period of heavy rain and thunderstorms. There are strong winds near our mountain top levels and these winds can translate down to the surface in intense thunderstorms. The greatest risk of these gusty winds is on Friday.
This weekend the trough pulls away to the northeast, but leaves behind a plume of deep tropical moisture over us. Light winds and abundant moisture this weekend supports afternoon thunderstorms.
