UPDATE (11 a.m.) – The Winter Weather Advisory for the summits of Mauna Kea and Mauna Loa is no longer in effect.
From the National Weather Service:
The Winter Weather Advisory for the Big Island Summits was cancelled this morning as satellite and radar show little activity over and immediately upstream of the Big Island. The area of thunderstorms that moved over/near the Big Island overnight has moved south of the coastal waters south of the Big Island, taking with it the main threat of layered clouds and showers. The upper level low remains about 300 miles northeast of the Big Island this morning, and the models are in good agreement with the low lifting north over the next 24 hours. There are some thunderstorms that remain near the upper low, and the atmosphere over the Big Islands remains unstable. Can’t rule out an isolated thunderstorm or two developing over the Big Island which would produce winter weather at the summits, but with the main threat having passed, the advisory was cancelled.
(BIVN) – The road to the summit of Mauna Kea is closed due to “High Humidity, Below Freezing temperatures, Ice and Snow on the roadways”, rangers say, as a Winter Weather Advisory is in effect for Hawaiʻi Island summits.
The National Weather Service says:
An upper level low will decrease temperatures over the Big Island summits below the freezing level and produce convective snow showers through Sunday morning.
Snow occurring. Plan on slippery road conditions. Storm total snow accumulations around three inches are expected.
A Winter Weather Advisory for snow means periods of snow will cause travel difficulties. Be prepared for snow covered roads and limited visibilities, and use extreme caution while driving.
Forecasters say the Winter Weather Advisory is in effect until 6 a.m. Sunday.
Maunakea Rangers will be making checks and this message will be updated as conditions change.
