Extreme Heatwave Sweeping Across the United States: Tips to Stay Cool and Safe
A dangerous heat wave is sweeping across the United States, with triple-digit temperatures expected in the Southwest and Great Plains before moving eastward. Meteorologists warn that a high-pressure system could trap oppressive heat for over a week, affecting up to two-thirds of the country. People are advised to stay hydrated and seek cool places to avoid the extreme temperatures, which will be significantly warmer than usual, even at night.
The heat dome, caused by high pressure trapping hot air and blocking cooling winds and rain, is particularly strong in the Dakotas, with temperatures exceeding 100 F (37 C) in North Dakota. The National Weather Service predicts that over 90 local temperature records will be tied or broken, with many of them being overnight heat records. Cities like Fort Lauderdale, Miami, and Charleston won't see temperatures drop below 80 F (27 C) at night.
States like Nevada, Utah, and Colorado are also experiencing record highs, with Nevada facing temperatures higher than usual. The heatwave poses a risk of wildfires in dry areas like the Rockies, where dry thunderstorms could develop. Scientists attribute the intensity and duration of heatwaves to climate change caused by the burning of fossil fuels.
This year's temperatures are also influenced by El Nino, a natural warming of the equatorial Pacific that affects global weather patterns. The current El Nino, expected to be one of the most intense since 1950, could further exacerbate the heatwave. With an 81% chance of becoming "very strong" by fall, the heatwave is likely to persist. Staying hydrated and finding cool spaces are crucial during this extreme weather event.
