A significant heat wave is affecting New England, prompting various responses from local communities and officials. In Boston, Mayor Michelle Wu declared a heat emergency from Tuesday to Thursday, with temperatures expected to approach 100 degrees. Cooling centers, splash pads, and public pools are being opened, and outdoor activities are being adjusted to mitigate the heat's impact. New Hampshire utility companies, including Eversource, assure that their systems can handle the increased demand, although they encourage conservation to save on bills. Bergen County, NJ, also issued a heat advisory, and recreational facilities like Darlington County Lake are being made available to residents. The National Weather Service forecasts that this intense heat, driven by a heat dome, will likely persist for several days, impacting millions across the region.
