It's not officially summer yet, but the East Coast is broiling under its first heat wave.
Heat advisories were posted from Maine to the Carolinas. Meteorologists say the record-breaking heat will continue for the next few days.
The National Weather Service says an area of high pressure off the U.S. coast known as a "Bermuda High" will keep things very hot and humid.
People working outside are being cautioned to drink lots of fluids and medical professionals say to watch for the signs of heat stroke.
The weather service warns that heat is the number one weather-related killer. More than 1,500 people die from excessive heat each year.
