Rains over Maui have lessened, but stream levels remain high, prompting the National Weather Service to extend a flood advisory for the island.

Forecasters said stream gauges remained high even though rains have lessened at 9:36 a.m.

The advisory includes Kanaha Beach Park, Wailuku, Waihee, Waiehu, Spreckelsville, Pauwela, Paia, Napili, Kapalua, Kahakuloa, Kaanapali, Huelo, Hookipa Beach Park, Honolua, Honokowai, Honokohau and Haiku.

The weather service warns residents to stay away from streams, drainage ditches and low-lying areas prone to flooding.

The rain could also cause hazardous driving conditions due to water on roads, reduced visibility and poor braking action.

People should not to cross fast-flowing or rising waters in vehicles or on foot.

A slow-moving weather system passing over the state is responsible for the rains on Maui Monday and for rains over Oahu Sunday night into Monday morning.

The rains are expected to move over the Big Island later Monday.

Tradewinds should pick up after weather system passes, blowing away the vog and humidity that lingered over the islands last week.

But lingering moisture from the weather system will continue to bring rain to windward and mauka areas, with some showers blown over to leeward areas by strong treadewinds.

Tradewinds Monday are expected to blow at 15 to 25 mph, with 35 mph gusts.

Along with the wind and rain, surf is rising on north and east shores.

A high surf advisory is in effect until 6 p.m. Tuesday.

Surf is expected to be 10 to 15 feet along north shores and 6 to 9 feet along east shores Monday.
