Summer 2024 is shaping up to be a record-breaking season, with unprecedented temperatures and successive heat waves affecting a large portion of the United States. A high pressure dome over the West is expanding, bringing sizzling temperatures from the Pacific Northwest to the South for much of August. More than 36 million Americans are under advisories for dangerous heat, with temperatures nearing 105 degrees in Plains states like Montana, North Dakota, and Nebraska.
The Gulf Coast and the South are also facing triple-digit highs, with Louisiana and Mississippi experiencing extremely hot temperatures. The West, Southwest, and Pacific Northwest are already sweltering under the high pressure dome, with excessive heat warnings in effect for several regions.
The prolonged heat poses a risk of heat-related illness, particularly in interior areas of the Northwest, the Rocky Mountains, the desert Southwest, and Southern California. Residents are urged to take precautions such as staying hydrated, seeking shade, and avoiding strenuous activities during the hottest parts of the day.
The weather service expects the heat wave to persist throughout the week, with temperatures in the 110s forecasted for the Imperial County deserts in California. The Gulf Coast may also see high humidity levels that could exacerbate the heat index, increasing the risk of heat-related illnesses.
While a cold front may bring some relief later in the week, the official forecast calls for continued hot weather. Climate Central has noted that extreme heat events are becoming more common due to climate change, emphasizing the importance of taking precautions and staying informed during periods of intense heat.
