Raleigh, N.C. — An early season heat wave is expected to bring more record-breaking temperatures and poor air quality to much of North Carolina.

Heat advisories were issued from much of the eastern half of the state Sunday.

The hot, stagnant weather has also prompted air quality officials to issue a code orange health notice for poor air quality around Charlotte, Greensboro and Raleigh.

Highs were in the upper 90s across the eastern half of North Carolina on Saturday, and the Raleigh-Durham International Airport reached 100 degrees to set a record for the date.

Forecasters say the heat wave will continue for a few more days and highs could be a few degrees warmer on Sunday.

The state departments of Health and of Crime Control and Public Safety suggest these tips for keeping cool: 

• Do not leave children or animals in a parked car, even for just a few minutes.
• Drink plenty of fluids, preferably water, especially if you must spend time outside.
• Wear lightweight, light-colored, loose-fitting clothing.
• Use sunscreen, sunglasses and a wide-brimmed hat to protect yourself from sunburn.
• Stay indoors in air-conditioning if possible.
• Take a cool shower or bath.
• Avoid cooking with the stove and oven.
