UPDATE: 7 p.m.

The Maui Crater Road Fire wildfire is now 80% contained with the burn area remaining at 574 acres, according to the Maui Fire Department. Firebreaks are four miles long and about 10- to 20-feet wide, with a contingency line about three miles long and 20- to 40-feet wide.

MFD personnel with an engine and a tanker will remain overnight to monitor conditions, with work resuming Monday.
