US Faces First Heat Wave: Millions Under Extreme Heat Warnings

The southwestern United States, including parts of California, Nevada, and Arizona, is experiencing its first heat wave of the season, leading to extreme heat warnings for over 28 million Americans. The National Weather Service (NWS) predicts scorching temperatures, with some areas expected to reach above 100 degrees Fahrenheit.

California’s central valley faces temperatures well above 100 degrees, with Furnace Creek in Death Valley hitting 112 degrees on Tuesday and possibly reaching 121 degrees by Thursday. In Nevada, Las Vegas could see temperatures exceeding 110 degrees, with a record-breaking 112 degrees expected on Thursday, according to NWS.

This heat wave, attributed to a “heat dome” phenomenon, is expected to persist until at least Friday evening. A heat dome occurs when a high-pressure system traps heat over an area, preventing clouds and causing excess sunshine, which further raises temperatures. This weather pattern has caused droughts and water shortages in Mexico and the southern U.S. border, claiming lives last month.

The NWS warns of widespread temperature records being tied or broken across the region affected by the heat wave. In light of these extreme conditions, U.S. Customs and Border Protection officials have reported four migrant deaths due to heat strokes while attempting to cross the southern border in El Paso, Texas, last weekend. Chief Anthony Good has urged migrants to avoid crossing illegally during such extreme weather, emphasizing the dangers of the desert environment, especially in summer.

The NWS advises residents in affected areas to stay hydrated, avoid prolonged outdoor activities, and check on vulnerable populations such as the elderly and children.
