A record-breaking heatwave continues to scorch America.
The Eastern part of the country is at extreme heat risk, according to Heat.gov, as record temperatures are expected to continue through Saturday, July 20.
Over 100 million Americans are under a heat advisory, meaning the temperature and humidity can be potentially dangerous to human health.
Weather.gov offers safety tips to help Americans stay healthy in the heatwave, including staying well hydrated, avoiding sun exposure, reducing strenuous activities, and opting for air-conditioned and cool spaces, whenever possible.
Cold may feel like a distant memory for many Americans. This past winter was the warmest winter on record, with many major cities experiencing winter temperatures 8 to 12 degrees Fahrenheit above the historical average.
It's been warm, and it's only heating up. New York City is experiencing its third heatwave of summer 2024, with Monday's high expected at 97 degrees and a heat index potentially as high as 103 degrees. In Burlington, Vermont, highs of 90 are expected, with a heat index of 98. Connecticut, Massachusetts, and Rhode Island are all under a heat advisory, with a heat index of 103 expected. South Florida is looking at a heat index of 107 to 112, while today's high in Phoenix is 107, with a potential heat index of 110.
The good news: This heat won't last forever. Later this week, the eastern U.S. will cool off, though a severe thunderstorm risk is part of that cooling phase.
"A large dome of cool air from Canada is forecast to bring a welcome relief to the heat across much of the eastern two-thirds of the country as the new week progresses," reports NWS Weather Prediction Center. "Prior to the arrival of the cool air, high temperatures will be well up into the 100s in the central Plains and near 100 degrees over the interior Mid-Atlantic."
Rain and thunderstorms are also predicted in the Midwest and Ohio Valley before the cold front sets in, and the Pacific Northwest is also expected to see high temperatures in the hundreds later this week.
