The heat is expected to last well into the next work week as well. Temperatures will be in the low 90s until next Wednesday.

"Extreme heat affects people of all ages, but some New Yorkers are more vulnerable than others, especially the elderly and people with chronic medical conditions," New York City Commissioner Joseph Esposito said in a statement. “Stay safe by staying cool — use air conditioning, drink lots of water and check in on friends and family."

Along with the heat, an Air Quality Advisory has been put in place for Friday due to heavy smog levels. The state warns people sensitive to elevated ground-level smog should avoid prolonged periods outdoors and limit exercise.
