Gusty Kona winds and heavy rains are in store for the Hawaiian islands this weekend as a strong cold front approaches the islands.

Forecasters from the National Weather Service say that current southwest winds over Kauai and Oahu will increase Friday, and over Maui Saturday.

“These ‘Kona’ winds will become especially gusty over windward areas, potentially resulting in power outages and flying tree branches, as winds accelerate down the mountains,” weather officials said in a special weather statement today.

Accompanying the cold front will be a band of heavy showers with brief thunderstorms, forecasters said. Kauai should expect to see the shower band Friday afternoon, with Oahu getting it Friday night or Saturday morning. It’s expected to stall near Maui County or Hawaii island Saturday night.
