Extreme Heat Warning for Inland Empire: Stay Cool, Hydrate

Residents across the San Bernardino and Riverside County Valleys, also known as the Inland Empire, are advised to take immediate precautions as an Extreme Heat Warning is now in effect. Issued by the National Weather Service (NWS) San Diego, the warning anticipates dangerously hot conditions with high temperatures reaching between the upper 90s and 105 degrees Fahrenheit. Nights will offer little relief, with low temperatures remaining warm in the upper 60s to mid-70s.

This severe heat event began today, October 5, 2026, at 11:29 AM PDT, and is expected to continue until Thursday, October 8, 2026, at 8:00 PM PDT. The NWS emphasizes that heat-related illnesses can increase significantly during such conditions.

To ensure safety, residents are urged to drink plenty of fluids, stay in air-conditioned rooms, and remain out of the sun. It is crucial to check on relatives and neighbors, especially those who may be more vulnerable to heat. Never leave young children or pets unattended in vehicles, as car interiors can reach lethal temperatures rapidly. While not directly related to heat, the NWS also advises caution when driving high-profile vehicles due to strong winds, which can make driving difficult.
