Interior California Braces for a Week of Triple-Digit Heat

A heat wave is forecast for inland Mendocino, Humboldt and Trinity counties this week, with triple-digit highs and Trinity County possibly reaching 114–116°F on Tuesday and Wednesday; inland Mendocino could hit 100s–108, while coastal Humboldt stays cooler in the 60s–70s. The National Weather Service has issued a Heat Advisory for interior areas, starting Monday, with heat potentially persisting into the end of the week. Patchy smoke may affect the region, and residents should stay hydrated, limit outdoor activity during peak sun, check on vulnerable neighbors, and ensure pets have shade and water.
