Things are going to be heating up this holiday weekend, with inland temperatures forecast to hit the 90s to low 100s in inland areas, including Willow Creek, Hoopa and Orleans, starting Sunday and running through mid-week.

“The threat for heat related illness will be elevated Sunday through Wednesday for vulnerable people such as the elderly, young children, and those working and recreating for a prolonged amount of time outdoors,” a notice from the Eureka office of the National Weather Service states.

Coastal areas will be in the 60s to 70s.

While higher temperatures may make a trip to the river tempting, the NWS cautions that waters are still running swift and cold this time of year.
