The rain and snow is spurred by especially strong trade winds pushing moisture ashore.

While the rain isn't consistent, rainfall rates at times are upwards of a half-inch per hour, which equates to some heavy snow on the highest peaks of Hawaii.

Snowfall in the 50th state isn't completely out of the ordinary. Snow usually falls at the highest altitudes a few times a year, but it rarely sticks around for more than a few days.
