The National Weather Service has issued an excessive heat warning for much of Gilliam, Sherman and Wheeler County.
The heat warning was issued today and will remain in place throughout the weekend.
Temperatures in the John Day River Territory will climb to 110 in Moro on Monday and 106 in Condon and Fossil.
The area can expect to have six days of temperatures that are over 100 degrees and overnight lows in the high 60s.
The National Weather Service is urging the public to check on loved ones and neighbors, especially the elderly and to drink plenty of fluids.
It is also recommended that people stay in an air-conditioned room, stay out of the sun.
In addition, NOAA says that young children and pets should never be left unattended in vehicles under any circumstances. It is also important to know the signs and symptoms of heat exhaustion and heat stroke.
Wear lightweight and loose fitting clothing when possible. To reduce risk during outdoor work, the Occupational Safety and Health Administration (OSHA) recommends scheduling frequent rest breaks in shaded or air conditioned environments. Anyone overcome by heat should be moved to a cool and shaded location and 911 should be called right away.
