A cold front expected to bring heavy rains to the Big Island and Maui late Friday failed to produce much in the way of showers overnight.

The National Weather Service said the decaying cold front, combined with a lingering upper-level trough, or low-pressure system, still could produce showers over the eastern end of the state over the next several days.

Data from rain gauges showed that most of the rain that fell on the Big Island over the past 24 hours occurred in Kona on Friday.

However, a high-wind warning remained in effect until 6 p.m. Sunday night for the summits of Mauna Kea and Mauna Loa where gusts of up to 100 mph were possible, the weather service said.


Forecasters said some snow is still possible over the Big Island summits as the cloud layers reach that island. With summit temperatures remaining around freezing today, the winter weather advisory for possible snow and blowing snow remained in effect for the summits until 6 p.m. today.


The upper-level trough was expected to move to the northeast over the next several days, bringing dryer weather first to Kauai and Oahu and later to the eastern part of the state.

The National Weather Service has issued a flash flood watch for the Big Island through at least 6 a.m. Saturday.


Forecasters said a cold front moving from west to east down the island chain, combined with low pressure in the upper atmosphere, is expected to bring heavy showers to both windward and leeward areas of the island tonight and into Saturday morning.

The front is forecast to stall near the Big Island late Saturday.

A high wind warning and winter weather advisory have also been issued for the summits of Mauna Kea and Mauna Loa until 6 p.m. Saturday.
