LOS ANGELES — The windy, flame-fanning weather that put the nation's second most-populous metropolitan region on edge eased up Wednesday as firefighters made significant gains against the two massive wildfires burning around Los Angeles.
A ''Particularly Dangerous Situation'' red-flag warning expired without causing explosive fire growth as feared, though forecasters said gusty winds could linger into early Thursday, mostly in the mountains. Temperatures were predicted to drop, and a deep marine layer was expected to move in over the weekend, according to the National Weather Service in Los Angeles.
Those improved conditions should help fire crews make even more headway and allow residents to return to their neighborhoods to begin rebuilding.
But Santa Ana winds could return early next week.
''Good news: We are expecting a much-needed break from the fire weather concerns to close this week,'' the weather service posted on social media Wednesday afternoon. ''Bad News: Next week is a concern. While confident that we will NOT see a repeat of last week, dangerous fire weather conditions are expected.''
Still, firefighters and police faced new challenges. Since the beginning of the outbreak last week, authorities have arrested about half a dozen people accused of setting new, small fires that were quickly knocked down.
One suspect admitted starting a fire in a tree ''because he liked the smell of burning leaves,'' Los Angeles Police Chief Jim McDonnell said. Another said ''she enjoyed causing chaos and destruction,'' the chief said Wednesday.
Authorities have not determined a cause for the major blazes in what is on track to become the nation's costliest fire disaster, with at least 25 people dead and thousands of homes destroyed.
