Weather Alerts and Heat Warnings🥵
An Extreme Heat Warning is in effect across portions of Los Angeles, Ventura, and Santa Barbara counties, including many valleys, mountains, coastal areas, and inland coastal communities. Some affected locations could reach temperatures between 100°F and 110°F.
The warning is scheduled to continue through 8 p.m. Friday, August 28, although the precise alert area varies by community.
Heat-safety checklist
—Limit strenuous outdoor activity, especially between late morning and early evening.
—Move exercise to early morning or after sunset.
—Use air conditioning or visit a cooling center if your home becomes dangerously warm.
—Check on older adults, young children, neighbors, and anyone without reliable air conditioning.
—Never leave children, older adults, or pets in a parked vehicle.
—Watch for dizziness, headache, nausea, unusual fatigue, confusion, or fainting.
—Call 911 immediately if someone shows signs of heat stroke, including confusion, loss of consciousness, or extremely hot skin.
🏁Commuter Forecast: “The 405 Is Hot Enough—Please Don’t Add Drama”
Live traffic conditions can change rapidly, and the available incident feeds do not provide a reliable complete snapshot for every Los Angeles freeway at publication time. Check Caltrans QuickMap, CHP incident reports, and your preferred navigation app immediately before departure.
Morning commute🚘
Expect the usual congestion on the 405, 101, 110, 5, and 10 freeways, with heat potentially increasing vehicle and roadside-assistance problems.
Allow additional time through the 405 Sepulveda Pass, particularly where construction or lane reductions remain active.
Watch for disabled vehicles and collision-related slowdowns near major interchanges.
Leave earlier if possible, and keep extra water in the vehicle.
Afternoon and evening commute
The hottest pavement and strongest heat stress will arrive during the afternoon drive home.
Avoid unnecessary freeway shoulders; they may expose drivers and passengers to dangerous heat while waiting for assistance.
Keep your fuel level above empty, check tire pressure, and confirm that your air conditioning is working before departure.
Carry water, a phone charger, and basic emergency supplies.
Never idle or park with a child or pet inside the vehicle, even briefly.
Healthy Hydration Tip💦
Start drinking water before leaving home and carry a refillable bottle throughout the day. For prolonged outdoor activity or heavy sweating, pair water with an electrolyte-containing drink or a water-rich snack such as watermelon, oranges, or cucumber. Keep alcohol and excessive caffeine out of the hydration plan during extreme heat.
Los Angeles commuters should treat today as a heat-management day: check the forecast and traffic before leaving, reduce outdoor exertion, and build extra time into every trip. The heat warning remains the headline, but preparation—water, shade, working air conditioning, and a live route check—can keep Wednesday from becoming a roadside emergency.
A current Caltrans advisory also lists overnight work involving the northbound 133 Toll Road connector to northbound I-405 from 11:59 p.m. through 5 a.m. on August 25–26; travelers using that route should verify whether the closure has ended before heading out.
