Gusts up to 50 mph forecast for parts of Big Island now under wind advisory

A wind advisory is in effect for north, northwest, south and southeast portions of the Big Island until 6 p.m. today (June 22), including North and South Kohala as well as parts of Hāmākua, North Kona, Kaʻū and Puna.

Forecasters earlier this morning even suggested there could be some fire weather concerns as trade winds strengthen.

The National Weather Service office in Honolulu forecasts northeast winds of 15 to 30 mph, with gusts up to 50 mph, in the advisory locations.

Winds this strong can tear off shingles, knock down tree branches, blow away tents and awnings and make it difficult to steer, especially for drivers of high-profile vehicles.

The public is advised:

• Watch out for falling tree branches.
• Make sure tents and awnings are secure or taken down.
• Be prepared for power outages.

The statewide forecast as of about 3 a.m. called for dry weather with gradually strengthening trade winds today.

A dry and stable airmass in place over the islands was evident on radar as only a few isolated showers were seen impacting windward and mauka locations and other areas remained dry. Trades are gaining strength from a tight pressure gradient created because of a surface high northeast of the state.

“Across Maui and Hawaiʻi counties, we could see some fire weather concerns, especially with the dry conditions in place, strengthening winds and where fuels are drier,” the early morning forecast said. “We urge you to limit activities outdoors that could cause a spark to reduce the risk of any fires occurring.”
