If you’re living above the fog line, you’re going to want to buckle up for a crazy hot Labor Day weekend. These look to be some of the hottest days of the year.

Check out these current forecast highs:

Redway:

• Saturday: 97°F
• Sunday: 103°F
• Monday: 98°F

Hoopa:

• Saturday: 98°F
• Sunday: 108°F
• Monday: 105°F

The coast is looks to top out at around 70°F, plus or minus a few.

But 108 is … not fun. The National Weather Service has issued an excessive heat warning for the Humboldt County Interior, and indeed almost the entirety of inland northern California. You know the deal: Drink lots of water, make sure you or your loved ones have a way to stay cool, especially if you or they are especially vulnerable.

These days there’s always the danger of the electrical grid collapsing under the load needed to power millions of air conditioners, so last time the state got a blast of sun this intense PG&E warned that it might have to shut off certain customers on a rotating basis. There has been no such warning for this weekend — yet — but the utility has issued a “Flex Alert,” asking all customers to conserve during peak hours.

From PG&E:

Pacific Gas and Electric Company (PG&E) urges its customers to conserve energy during afternoons and evenings over the three-day Labor Day weekend. The state’s grid operator has issued a Flex Alert, based on a forecast of increased power demand due to expected high temperatures.

Customers are asked to reduce their energy use from 3 p.m. until 9 p.m. each day, Saturday through Monday, when air conditioners drive consumption. By doing so, customers can help make sure the state has enough supply to meet demand for electricity.

Some helpful tips for conserving power:

• Avoid using electrical appliances and devices from 3 p.m. until 9 p.m. Put off tasks such as vacuuming, laundry, dish washing and computer time until after 9 p.m.
• Adjust your thermostat to 78 degrees or higher or turn it off if you will be away from home. Use a fan instead of air conditioning when possible.
• Draw drapes and turn off unnecessary lighting.
• Limit the opening of refrigerators, which is a major user of electricity in most homes. The average refrigerator is opened 33 times a day.
• Keep refrigerator full (with bottles of water if nothing else) and unplug your second refrigerator, if you have one.
• Avoid using the oven. Instead, cook on the stove, use a microwave or grill outside.
• Set your pool pump to run overnight instead of during the day.
