A red flag warning was extended Wednesday afternoon and is in effect through Friday morning for most of Los Angeles and Ventura counties due to extremely low humidity and offshore wind gusts, according to the National Weather Service.

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

The dangerous fire conditions in Southern California are expected to last a little longer than previously anticipated. The red flag warning was set to expire at 2 p.m., but the Los Angeles County Sheriff’s Department said in an alert that it had been extended until 10 p.
