Hawaii is under a slew of weather advisories as a weekend storm system arrived today, packing heavy rain and strong winds statewide, and a foot or more of snow on Hawaii island summits, forecasters said.

The storm front moved over the western islands overnight and is expected to stall out over Maui later today, according to the National Weather Service in Honolulu.

Early today, rain and moderate to breezy north winds with frequent gusts of 35 to 40 mph were recorded across Kauai and Oahu, with the storm system moving over Molokai later in the morning.

The weather service said before dawn this morning a large tree was reported down on Kapolei Parkway near Costco due to the high winds.

“Radar imagery shows scattered to numerous showers across the smaller islands, with a few showers affecting east and southeast facing slopes of the Big Island,” NWS forecasters said early this morning. The storm system threatens to bring heavy rainfall and flash flooding across the state, “with a couple rumbles of thunder not out of the question Sunday through Monday.”

A Flood Watch is in effect from noon today through Monday afternoon, with the greatest risk for flash flooding in windward areas, officials said.

In addition, the weather service issued the following alerts:

>> A high wind watch for all islands with sustained east winds of 25 to 40 mph and gusts over 60 mph possible. “Take precautions now to protect property. Tie down loose objects,” forecasters said.

>> A high surf warning for north and west shores of Kahoolawe, Kauai, Lanai, Molokai, and Oahu, and the north shores of Maui until 6 p.m. today with “dangerously large breaking waves” of 20 to 26 feet along north shores and 15 to 20 feet along west shores.

>> A high surf advisory for the west shores of Hawaii island with waves from 7 to 10 feet until 6 p.m. today.

>> A winter storm watch for Big Island summits over 11,000 feet from this evening through Monday afternoon. Forecasters expect heavy snow with total accumulations of over 12 inches possible and winds gusts as high as 45 mph.

Forecasters said “conditions will gradually improve for the middle and latter portion of next week, although a somewhat showery and breezy tradewind pattern will likely persist.”
