Showers are likely to continue off-and-on through the week for the Hilo side, although continued thunderstorms are unlikely.

Mauna Kea rangers closed the road to the summit to the public at the Visitor Information Station due to snow and black ice at the summit. The temperature at 4 p.m. was 29.6 degrees Fahrenheit with easterly winds blowing at 42 mph with fog and hail.

A winter storm warning is posted until 6 a.m. today and the forecast is for additional winter weather conditions through this morning.
