Eureka’s National Weather Service office has issued an Excessive Heat Watch for areas of Northern and Southern Humboldt this weekend.

Temperatures as hot as 108 degrees will be possible along Humboldt’s interior valleys between Saturday afternoon and Monday evening.

“Extreme heat will significantly increase the potential for heat related illnesses, particularly for those working or participating in outdoor activities,” the NWS stated. “Be prepared to drink plenty of fluids, stay in an air- conditioned room, stay out of the sun and check up on relatives and neighbors. Young children and pets should never be left unattended in vehicles under any circumstances. This is especially true during warm or hot weather when car interiors can reach lethal temperatures in a matter of minutes.”

Coastal areas, meanwhile, are forecast to remain in the low to mid 70s. A Coastal Flood Advisory has been issued for the Humboldt Bay area between 9 p.m. tonight and 1 p.m. tomorrow.

“High astronomical tides will likely lead to some coastal flooding in low-lying areas around Humboldt Bay,” the NWS stated. “Areas that are particularly at risk include: King Salmon and Jackson Ranch Road in the Arcata Bottoms.”
