Heat Wave Scorches West and South with Temperatures up to 118°F

A prolonged heat wave is gripping the Southwest and South-Central United States, with the National Weather Service warning of dangerously high temperatures and heat-related illness risks. An Extreme Heat Warning issued Friday covers Death Valley, the lower Colorado River Valley and parts of Arizona, California and Nevada, where temperatures may reach 115 to 118 degrees Fahrenheit and other locations may reach 107 to 110 degrees. In Texas, heat warnings and advisories cover areas, with North Texas temperatures reaching 108 degrees and heat-index values approaching 109 to 111 degrees in several regions. Austin and San Antonio are experiencing persistent triple-digit temperatures. The weather service says a strong ridge of high pressure is sustaining the pattern, with limited rainfall and little relief expected through next week. The original report's references to Colorado and New Jersey illness spikes were not independently verified in accessible current sources and should be omitted unless separately documented.
