Firefighters gain upper hand over wildfire in suburban Los Angeles

Assisted by rising humidity, firefighters gained an upper hand over a massive wildfire which was moving toward Los Angeles, fire commanders said on Tuesday.

The 190-square-mile (304-square-kilometer) Station Fire continued to burgeon, but the rate of increase has diminished, according to the Los Angeles County Fire Department (LACFD).

It is also threatening Mount Wilson -- the site of a historic observatory and an array of broadcast communications towers used by the bulk of Southern California's television and radio stations, as well as public safety agencies.

But for the first time in the week, firefighters managed to slow the fire's advance.
