Extreme heat and violent storms threaten millions across the US this weekend

The West Coast is preparing for a sharp rise in temperatures this weekend. Forecasters warn that highs could climb 10 to 25 degrees above normal, affecting millions across the US. Extreme heat and severe storms are expected to disrupt large regions. An estimated 26 million people will face extreme heat across the West, the Plains and the Southeast. Temperatures may hit 108 degrees in some spots, with most areas seeing highs in the 90s—5 to 10 degrees above mid-June averages. Some of this unusual warmth could be tied to El Niño, a climate pattern warming Pacific surface waters.

Earlier this week, severe weather left 13 million people under flood watches and caused widespread power cuts. In Kansas alone, 35,000 customers lost electricity at one point. Severe thunderstorm warnings were already active in parts of Nebraska, Kansas, Tennessee, Arkansas, Kentucky and North Carolina.

By Sunday, showers and thunderstorms may threaten 54 million people in the mid-Atlantic, Appalachians and Ohio Valley. Another 22 million from Texas to Kentucky, including cities like Kansas City, Tulsa, Wichita and Springfield, face risks of strong storms. After midnight, nocturnal tornadoes, wind gusts over 75 mph and large hail remain possible in many areas. The weekend will bring extreme heat and storm risks to wide parts of the country. Millions are advised to prepare for dangerous conditions, including record-breaking temperatures and severe weather. Authorities continue to monitor the situation closely.
