A relentless heat wave with triple-digit temperatures is continuing to affect millions of people in the South. Much of Texas and Louisiana will have temperatures at the 100-degree mark by Sunday afternoon, but the heavy humidity will cause heat indexes to soar another 10 to 20 degrees, forecasts show. More than 33 million Americans are currently under heat alerts from Houston to New Orleans.
