MAUNA KEA — More snow is expected to fall on Hawaii mountaintops as a winter storm warning goes into effect through Monday morning.

Yes, it snows in Hawaii, Matthew Foster, a meteorologist with the National Weather Service in Honolulu, said he had to explain to some surprised out-of-state callers Friday.

“Typically when we get these snow events, it does get a lot of attention,” he said, adding that he explains to curious callers that the snow is falling in a small, remote area where there are mainly telescopes and scientists. “We do have very high mountains here.”

Once they realize the heights of the mountains, snow in the island state makes a little more sense, said Ryan Lyman, forecast meteorologist with the Mauna Kea Weather Center. Mauna Kea is nearly 14,000 feet above sea level.

Hawaii News Now reports up to a foot more of snow could fall by Monday. A previous warning was lifted Saturday for a storm system that also brought frozen precipitation to higher elevations and heavy rain elsewhere.

The summits of Mauna Loa and Mauna Kea on Hawaii’s Big Island are closed amid icy, windy, hazardous conditions.

The National Park Service says people can see the deepening layer of snow at 10,000 feet.

Hawaii also is under a flash flood watch into Sunday afternoon.
