LA County supervisor calls for investigation about the slow evacuation of residents in one community as fires broke out across Los Angeles

The National Weather Service on Tuesday extended its red flag warning for Southern California until Thursday evening.

As firefighters struggle to gain control of massive and deadly wildfires that are raging across parts of the Los Angeles area, the region is once again bracing for the potential of new fires and for current ones to intensify as a new storm system heads for the state.

This weekend's cool temperatures and higher humidity are expected to give way to more Santa Anas and a new red flag warning Monday.

Southern California will continue to face "dangerous fire weather conditions" including strong Santa Ana winds and extremely low humidity through later this week, forecasters said Tuesday.
