Snow continues to fall on both summits of Maunakea and Mauna Loa. More weather downslope continues to move upwards towards the summits and could possibly see about an inch or two of new snowfall on the summit by sunset on Tuesday evening.


Early reports show that parts of Maunakea seen up over a foot of snowfall occur in the last 24 hours, however, some areas may see very high snowdrifts. The snowplow was successfully able to make up to the summit of Maunakea, however, blizzard-like conditions continue on the summit.

Mauna Loa summit continues to see snowfall as well, however, snow was falling at 12,000-foot elevation and up. No visible snow was noted around the NOAA Observatories at Mauna Loa (11,135-foot elevation), just rainfall was recorded during the overnight periods.


Approximate snowfall on Mauna Loa was estimated to be 8 to 9-inches fell on the summit. Possibility of about 1/2 to 1-inch of snow should be expected through today. The earliest indication shows the Southeast and Southern Slopes of Mauna Loa seen the heaviest snowfall.
