The lava flow heading toward Pahoa has slowed and scientists now project the lava could reach the outskirts of Pahoa on Nov. 1.

The flow advanced only about 45 yards since Monday, Hawaii County Civil Defense said Tuesday morning after a morning overflight of the lava.

Hawaiian Volcano Observatory scientists estimated on Monday that the flow is advancing at an average rate of about 80 yards a day, suggesting it could reach Apaa Street on the outskirts of Pahoa in about 19 days.

Over the weekend, the flow moved about 240 yards downslope to the northeast.

The flow is about .6 to .7 miles from Apaa Street, near the Pahoa Transfer Station.

Scientists caution that the lava’s advance has varied significantly during the past month and week, and the projection is subject to change.

At this point, no homes are threatened and no evacuations have been ordered.

Smoke from burning vegetation in contact with the lava was moderate to heavy in the Kaohe Homesteads area, with light winds.

County officials said there is no brush fire threat at this time.
