A Heat Advisory is still in force for almost all of southern New England, with the exception of the Berkshires, Cape Cod, and the Islands, from 11 a.m. Monday through 8 p.m. Wednesday, according to the National Weather Service in Norton. Tuesday afternoon is predicted to bring the worst of the heat, particularly along the I-95 corridor, where humidity will increase the likelihood of heat-related illnesses.
Residents are advised to use air conditioning, stay inside during the hottest afternoon hours, and keep an eye on their neighbors who may be at risk. Officials advise staying hydrated and refraining from physically demanding activities unless it is early in the morning or late at night. Dizziness, weariness, and nausea are signs of heat exhaustion; if these occur, get medical help.
Providence, Cambridge, Worcester, and Boston are among the major cities affected. The extreme heat could cause interruptions to municipal services and public schools. On Tuesday, several cooling centers will be open.
Wednesday is expected to be hot, hovering about 94°F, with the possibility of isolated thunderstorms providing some respite. With a lower high of 80°F on Thursday, there is a 50% chance of rain.
