Wu declares heat advisory in Boston through Friday

Boston has issued a heat advisory ahead of a string of muggy days, with temperatures expected to reach the high 80s, with the heat index expected to reach the 90s, through Friday.

"While this is not a heat emergency, we are advising people to take the necessary precautions such as taking breaks when working outside, staying hydrated and checking on each other in the heat," Boston Mayor Michelle Wu stated in a press release Tuesday.

Adrian Jordan, chief of emergency preparedness, said the Office of Emergency Management is working closely with the National Weather Service and Boston Public Health Commission to ensure resources are available for vulnerable populations during the heat wave.

Extreme heat waves can be dangerous and prolonged heat exposure could increase the risk of heat stroke and other illnesses, especially for children, older adults and people with chronic health conditions, Jordan said.

Facilities such as splash pads in playgrounds, city pools, and various Boston Public Library locations are open for the public to seek relief from the heat.
