UPDATE: 4:30 a.m.

The powerful low-pressure system north of the islands is expected to move toward the islands Friday and over the weekend, bringing with it very windy conditions and dangerous surf, forecasters say.

“While the details and exact timing still remain uncertain, this low will bring the potential for strong and gusty north to northwest winds from Friday into the weekend, with winds especially strong over ridges and mountaintops, and where they accelerate downslope,” the National Weather Service said in a bulletin.

“If you have outdoor plans for the weekend, be prepared for very windy conditions. If your plans include marine activities, you may want to consider postponing them.”

With regard to surf, weather officials expect the low-pressure system to generate “very large surf” along exposed north- and west-facing shores, with a chance for significant coastal flooding.


While high pressure north of the state will keep light to moderate trade winds in place through tonight, a cold front is on its way to the isles later this week, weather officials said.

Forecasters said “a rather complex weather scenario is potentially setting up across the area for the remainder of the week and on into early next week.”

A surface low developing north of the islands Wednesday through Thursday is expected to disrupt the trades, bringing afternoon clouds and showers over interior and mauka areas midweek. A cold front will then sweep through the islands Thursday night and Friday, ushering in brisk, northerly winds and showery conditions through the weekend.

By Saturday night, it is expected to be “rather windy” and cool temperatures, along with breezy to windy conditions early next week, “will make things not feel quite so tropical,” weather forecasters said.

Temperatures tonight and Wednesday night are expected to range from 59 to 67 degrees on Oahu’s South Shore, 61 to 68 degrees on the Waianae coast, 62 degrees on the North Shore, 58 to 64 degrees in Central Oahu and 63 to 68 degrees on the windward side, including Kailua, Kaneohe and Waimanalo.
