U.S. Forest Service firefighters stand near flames at the Williams fire in the Angeles National Forest on Sept. 4, 2012 north of Glendora.
Despite Wednesday's forecast packing a possible fire-starting lightning risk, raindrops from the remainder of a tropical storm in the region could help the fight against a 3,800-acre blaze in the San Gabriel Mountains northeast of Los Angeles
The area, located in Angeles National Forest, began to burn on Sunday, and was 24 percent contained before the rain started. The blaze called more than 1,100 firefighters to battle in the treacherous terrain -- at least seven responders have sustained injuries.
The fight is currently contained in the mountains and has not moved toward nearby foothill cities. Officials expect it to be fully surrounded on Sept. 13.
