Firefighters were investigating the cause of a fire today that engulfed a two-story home in Waipahu.

Nine fire companies with 35 firefighters responded to the two-alarm fire at 5:11 p.m. and found smoke and flames emanating from most of the structure, said Honolulu Fire Department Capt. David Jenkins.

Firefighters brought the flames under control at 5:24 p.m. and extinguished the fire by 6:13 p.m.

A man and woman in the home at the time the fire started noticed an odor of smoke and escaped without injury, Jenkins said. The American Red Cross was assisting.

The cause and damage estimate were under investigation.
