National Weather Service (NWS) meteorologists are confident that the ongoing red flag warnings will expire either Wednesday night or Thursday afternoon after being issued or extended multiple times as wildfires continue burning in Southern California.

Cal Fire crews are responding to the scene of a brush fire in Ramona that broke out early Tuesday morning, threatening at least one structure.

"If fire ignition occurs, conditions are favorable for very rapid fire spread and extreme fire behavior," the NWS warns.
