The excessive heatwave is expected to continue today after it forced some changes to local events in Fredericksburg on Saturday.

The heat index reached 110 degrees on Saturday and similar temperatures are anticipated for Sunday.

On Saturday, the Bluemont Concert series had to be moved to James Monroe High School because of the excessive heat. The Farmer's Market shut down at 1 p.m. for the same reasons, which is hours earlier than it normally closes at Hurkamp Park. The Motts Reservoir closed at 3 p.m. Saturday because of the extreme heat.

Sunday, the temperature is expected to reach 100 degrees with a 40 percent chance of rain or a late-night thunderstorm. After Sunday, temperatures are expected to decrease to a more reasonable level in the high 80s.

The Centers for Disease Control and Prevention offers the following tips to avoid heat-related illnesses:

• Wear light-colored, loose-fitting, breathable clothing.
• Stay indoors as much as possible. Try to limit outdoor activity to morning and evening, and rest often in shady areas.
• Drink often to stay hydrated, and avoid drinks with caffeine, alcohol or sugar.
• Take cool showers or baths.
• Never leave children or pets in a closed, parked vehicle.
• Protect yourself from the sun with a wide-brimmed hat, sunglasses and sunscreen – SPF 15 or higher. Put on sunscreen 30 minutes before going outside, and reapply it as directed.
• Use the stove and oven less to keep your home cooler, and try not to eat hot or heavy meals; they add heat to your body.
