HONOLULU (HawaiiNewsNow) - The cooling trade winds are going on yet another extended break, with forecasters predicting several days of light winds and muggy, hazy conditions.
Winds are expected to be weak east to east-southeast trades on Friday. The winds will be weak enough to allow for afternoon sea breezes, which will in turn allow afternoon clouds and pop-up showers to develop.
The trades are forecast to disappear by Saturday due to an unseasonable large and slow-moving trough in the central north Pacific. This weather feature will push a cold front near the islands during the weekend, causing the main low-level wind flow to shift southeasterly, and then maybe southerly Sunday and Monday, drawing up haze from the Big Island of Hawaii and muggy conditions from the south. Winds will be very light with a continuation of the afternoon sea breezes, clouds and pop-up showers, following by nighttime clearing.
The front is forecast to stall out just northwest of Kauai, which could bring a slightly higher chance of rainfall for the Garden Isle. Light trades aren't expected back until Wednesday or Thursday.
The National Weather Service said the extended disruption of the trade winds is unusual for this time of year.
