Firefighters on Tuesday held the line against two massive wildfires that have ravaged parts of Los Angeles for the past week, even as desert winds and a parched landscape presented extremely hazardous conditions.

Dangerous Santa Ana winds are expected to return to the Los Angeles area this week, potentially fueling the growth of new and existing wildfires, according to FOX Weather.

With the strongest gusts expected on Tuesday, extreme fire condition threats will prevail until midweek, L.A.-area fire chiefs say.
