The hills above the Moanalua Freeway were choked in haze from the vog that settled over Oahu yesterday.
Haze will clear up
Tradewinds were expected to return to Hawaii and help sweep away the volcanic haze except in the southern part of the Big Island, according to the National Weather Service.
The haze cloud covers a big area, forecaster Chris Brenchley pointed out yesterday. "Even with the trades starting to blow, we've got haze over the open waters still moving across until we're able to filter all that stuff out."
Light trades were expected to return to the state yesterday and conditions are expected to improve gradually today as the winds gain strength.
Even the vog-blanketed Big Island should see some improvement except in Kau and Kona, which are downwind of Kilauea in the trade wind pattern, Brenchley said. Erratic and gusty wind shifts could cause isolated showers in some unusual areas, the forecast said.
This means the normally drier leeward and central Oahu areas and Waikoloa on the Big Island will have some brief rains and possible ponding on the roads, Brenchley said.
