California, Arizona hit triple‑digit heat; farms and officials warn

Triple‑digit temperatures have spread across California's Central Valley and Arizona's Imperial County, prompting the National Weather Service to issue Extreme Heat Warnings through August 9. The alerts cite daytime highs of 98‑106 °F in the Cuyama Valley and 104‑118 °F in the Imperial Valley, warning of dangerous heat illness for vulnerable groups and outdoor workers.

In Tulare County, dairy operators are taking measures to protect cattle. Lawrence Family Farms, the 2026 Dairy of the Year, uses barn designs that keep interior temperatures 10‑15 °F cooler, while interim agricultural commissioner Christopher Greer notes that heat raises summer cattle mortality. Veterinarian Dr. Crystal Heath described symptoms such as panting, drooling and reduced feed intake. The farms and officials stress hydration, shade, and limiting strenuous activity to early morning or evening to reduce health risks for both animals and people.
