More than 170,000,000 people across the US are now under heat alerts, according to the National Weather Service.
The heat index may hit near 110°F in Washington, DC, Chicago and Detroit in the coming days. https://nbcnews.to/2LtWyhc (1/4)
Most won't be record-daily highs but record-high nighttime lows, and that lack of cooling can be dangerous, meteorologists say.
Officials are also concerned about smog, which is exacerbated by the heat and makes it harder for certain people to breathe. (2/4)
NYC Mayor de Blasio’s office on Wednesday said that approx. 500 cooling centers have been activated around the city.
“Extreme heat is dangerous, period,” de Blasio said in a statement. “I urge all New Yorkers to exercise caution this weekend as temperatures near 100." (3/4)
Relief is in sight, meteorologists say, but it’s days away. Temperatures will begin to cool off across the eastern half of the country early next week. (4/4) #NBCNewsThreads https://nbcnews.to/2LtWyhc
