Forecast: Heavy showers, thunderstorms possible for entire state

A band of enhanced clouds and showers associated with an old front is riding the trade winds and moving in from the northeast. Meanwhile, an upper level disturbance is moving across the state from the southwest. This combination will keep showery weather and abundant cloud cover in place through Friday, particularly over windward areas.

Some of the showers may be heavy at times and an isolated thunderstorm can't be ruled out. Due to last weekend's heavy rainfall, it won't take much to create run-off and flooding.

Stay alert and stay safe.

High pressure north of the state will keep a moderate to breezy trade wind flow in place through the weekend, before strengthening to locally windy levels for the first half of next week.  A more typical trade wind pattern will return Friday night through the first of next week, with showers favoring windward and mauka areas.

Wetter weather could return late Tuesday.

Surf is moderate along all shores. No advisory-sized swells are in the forecast.

Waves today will be 4-6 feet east, 3-5 feet north, 2-4 feet south, 2-3 feet west.

Flash flood watch for all islands through Friday.

Winter storm warning for the summits of the Big Island above 12,000 feet. Up to a foot of snow is possible.

Small craft advisory for most waters in the eastern half of our island state.
