Passing thunderstorms brought heavy rain to Hawaii island and a dusting of snow to the summit of Mauna Kea Thursday afternoon.

National Weather Service forecasters  issued a flood advisory for South Kohala and North Kona when radar showed rain rates in the 1- to 2-inch per hour range, with the heaviest rain near the Saddle Road junction at about 3 p.m..

The rains, caused by daytime heating, eased by early evening and the advisory was canceled.

Ian Morrison, a forecaster with the Honolulu office of the National Weather Service, said radar showed more rain clouds east of the island moving west towards the Hilo area tonight.

Morrison said Hawaii island could get more rain and perhaps thunderstorms again tomorrow.

Webcameras on the summit of Mauna Kea showed a light dusting of snow or ice at the summit. Much of it had melted by early evening, but some snow appeared to be still on the ground in the shade near the Canada-France-Hawaii Telescope at sunset.

Morrison said temperatures at the summit are near freezing during the day and below freezing at night.

The forecast for Honolulu calls for tradewinds to become light Friday, with partly sunny skies and scattered showers through the weekend.
