Officials Raise Health Concerns as Heatwave Intensifies Over Central, Eastern US VOANews The National Weather Service warned that dangerously high temperatures and humidity in the United States over the weekend could quickly cause heat stress or heat stroke, if precautions are not taken. The NWS advises people to check in on relatives and friends, especially the elderly. Temperatures have been rising in cities from the Midwest to the East Coast because of a high pressure system that has trapped the warm air. City officials are allowing public pools to stay open longer and municipalities are issuing advisories to inform the public about how best to deal with the heat. Forecasters say temperatures in New York City will reach 33 degrees Celsius Saturday, but with the humidity, it will feel like 43 degrees Celsius.
