New York City officials are warning people to drink water and stay cool as temperatures soar to an expected 95 degrees this week.

The city’s Office of Emergency Management says seniors over age 65 and people with chronic health problems are especially vulnerable in the hot weather.

Temperatures are forecast to hit or exceed 95 degrees on Monday and Tuesday. Prolonged exposure to the heat can be harmful and potentially fatal.

The hot weather will also cause elevated ozone levels. The New York State Department of Environmental Conservation on Monday issued an air quality health advisory.
