Fire weather just got a lot more serious for parts of Southern California. Cal Fire said yesterday that a Red Flag Warning has been expanded to cover portions of eastern Riverside and eastern San Diego counties, with strong winds, very low humidity and bone-dry vegetation teaming up to create dangerous conditions where any spark could turn into a fast-moving wildfire.

Officials are asking residents to skip any outdoor burning, keep trailer chains from dragging on the road, use extra care with equipment around dry grass and to call in any sign of smoke right away.

Where the Warning Applies

According to a Facebook update from CAL FIRE, the expanded Red Flag Warning took effect last night and now includes “portions of eastern Riverside and eastern San Diego counties.” The agency repeats a few key asks for locals: avoid outdoor burns, secure trailer chains and report any smoke to authorities as soon as you spot it.

What the Warning Means for Residents

A Red Flag Warning means that critical fire weather conditions are either occurring now or will shortly, the National Weather Service explains. It is the kind of mix of wind, heat and low humidity that can fuel very rapid fire spread.

The state’s burn-permit portal currently shows that burning is suspended in CAL FIRE jurisdictions that include Riverside and San Diego counties, a sign of how tight restrictions are under the warning.

Active Fires And Local Context

The timing is not great. Crews have been working on recent brush fires in the region, including the cross-border Border 6 blaze near Dulzura, which pushed into both U.S. and Mexican territory and triggered temporary evacuation warnings, according to KPBS. Hoodline’s earlier coverage of the Border-area blaze also noted road and trail closures near the fire’s footprint, underscoring how quickly access can change when conditions turn volatile.

Quick Safety Steps

CAL FIRE’s advice is straightforward, if not exactly convenient: skip outdoor burning, do not park vehicles on dry grass, double-check that trailer safety chains are not dragging and use extreme caution with any equipment that might throw sparks.

If you see smoke or flames, call 9-1-1 immediately and follow instructions from local fire or law enforcement agencies. In Red Flag conditions, even a small fire can stop being small in a hurry.
