Freezing rain with some snow showers are expected tonight on the summits of the Big Island.

Deep moisture moving onto the Big Island in the trade wind flow is expected to reach the summits, where temperatures will be below freezing tonight. Periods of rain will likely lead to some ice on roads and structures, with a few snow showers possible as well. The ice will result in very slippery conditions. Total ice accumulations of a light glaze are expected.

Be prepared for near zero visibilities and hazardous travel conditions.

A Winter Weather Advisory means that periods of freezing rain will cause travel difficulties. Be prepared for slippery roads. Slow down and use caution while driving.
