A second cold front this week is expected to begin moving down the island chain by Friday, ushering in the possibility for another bout of windy and rainy weather this weekend, the National Weather Service said.

The cold front is approaching as another cold front, which brought strong winds and heavy rain to Oahu, is exiting Hawaii island tonight.

Behind the departing front, a drier air mass is settling over the islands and will usher in pleasant conditions and colder-than-normal nighttime temperatures from tonight through Thursday, the Weather Service said.

Thursday night, impacts from the approaching cold front will begin reaching the islands.

A rain band associated with the incoming front will reach Kauai Friday and move down the island chain through Sunday. Forecasters said there was a chance for “widespread flooding over the smaller islands as the front moves through.”
