Rainbow shines during water drop on California's Thomas Fire

(STORYFUL) - California firefighters expected favorable conditions in the battle against the still-growing Thomas wildfire on Monday, December 18. The fire stood at 270,500 acres and was 45 percent contained Monday morning, the incident report said.

Cooler temperatures, higher humidity and a shift in the winds would make for more favorable conditions, a news report said. The better conditions were expected through Tuesday, though a wind event was predicted for Wednesday.

The Santa Barbara County Firefighters Union posted this video, saying their "Canadian friends" were performing the water drop on Flores Flats.
