Rain reduced the smoke rising from burning vegetation as lava from the Kilauea volcano continued to advance toward the village of Pahoa on Hawaii's Big Island on Sunday.
About 50 homes along what is described as a "corridor of risk" remain on evacuation alert, officials said.
The lava flow has been moving towards the village for weeks. More than 80 National Guard troops have arrived to provide security.
The glowing leading edge of the lava flow can reach temperatures of about 2,100 degrees Fahrenheit (1,149 degrees Celsius), officials said.
Kilauea has erupted continuously from its Pu'u O'o vent since 1983, with its latest lava flow beginning on June 27. The last home destroyed by lava on the Big Island was at the Royal Gardens subdivision in Kalapana in 2012.
