Skies should start clearing, but the potential for rain, even thunderstorms remains as the remnants of a weather system that passed through the islands Sunday linger of the state, National Weather Service forecasts said. Hawaii island summits may even see some snow tonight.

A winter weather advisory and a wind advisory are in effect for Mauna Kea and Mauna Loa through Tuesday morning. Forecasters say if thunderstorms develop over Hawaii island, they could drop snow over the summits.

Forecasts expect weak trade winds for the rest of the week before another weather system approaches the state, when we may see widespread showers over the weekend.

A high-surf advisory remains in effect through 6 p.m. today for the north and west shores of Niihau, Kauai and Molokai and the north shores of Oahu and Maui, where wave heights could reach 20 feet.

Forecasters predict strong breaking waves and shorebreak, as well as strong along-shore and rip currents that could make swimming difficult and dangerous.

The weather service issued flood advisories Sunday after heavy rain fell at a rate of 2 inches per hour early in the morning.

In the 24-hour period ending at 2 p.m. Sunday, 3.6 inches fell at Honouliuli and Waihee; about 3.4 inches fell on Ahuimanu; and nearly 3 inches was recorded at Kalaeloa.

The rainy weather may have contributed to a landslide that closed one westbound lane of Mokapu Boulevard in Kailua late this afternoon.

No injuries were reported.

Also Sunday, the state Department of Health’s Clean Water Branch issued a brown-water advisory for Oahu after heavy rains resulted in storm-water runoff entering coastal waters.
