NWS Issues Extreme Heat Warning for Inland Empire

Overview

• The National Weather Service has placed the San Bernardino and Riverside county valleys under an extreme heat warning for the coming week, forecasting dangerously hot afternoons and unusually warm nights.
• Forecast daytime highs are expected to reach the upper 90s to about 105°F while nighttime lows stay in the lower to mid 70s, reducing overnight relief and increasing cumulative heat stress for residents.
• A separate wind advisory warns of strong east winds expected during the weekend with sustained 15–25 mph gusts up to 45 mph that can blow unsecured objects, down tree limbs, and cause localized power outages.
• Officials urge people to drink plenty of fluids, stay in air‑conditioned places, avoid sun exposure, check on elderly and vulnerable neighbors, and never leave children or pets unattended in cars.
• The warning follows a broader late‑summer Southwest heat episode that has already exposed infrastructure and public‑health vulnerabilities, increasing the need for cooling shelters, worker rest protocols, and close utility monitoring.
