Two minor brush fires were discovered near the Lahaina Fire Station at about 3:30 p.m. Sunday.
They were brought under control within an hour, but traffic on Honoapiilani Highway was diverted to Lower Honoapiilani Road for a time to avoid the smoke.
No information on the cause and size of the fires was available late Sunday.
