Record-breaking cold temperatures were forecast for this morning, and Del Norte's wintry weather is expected to continue through the weekend.
Inland areas, including Gasquet, could see some snow Friday.
A hard freeze warning for this morning was issued by the National Weather Service. Lows in the mid-20s were forecast from 1 to 9 a.m. The record low for the date of Dec. 5 is 28, set in 1972.
The all-time low for Crescent City is 19 degrees, set on Dec. 21, 1990.
The temperatures could affect unprotected pipes, so it was advised to keep faucets dripping to avoid any breaks. It was also advised to bring any animals inside during the night.
The low-temperature record for Wednesday has already been broken. The Dec. 4 low was 30 degrees. The previous record for the date was 31, recorded in 1948.
Low temperatures are expected to be the trend through the weekend as the coast is affected by an air mass travelling down from the Arctic Circle, said Doug Boushey, a meteorologist for the National Weather Service in Eureka.
About half an inch of rain is expected to drop on Crescent City today and Friday, which could create patches of black ice on roads, Boushey said.
Meanwhile, Gasquet could get about 2 inches of snow Friday, Boushey said.
Inland low temperatures are expected to be in the mid-20s through the weekend, Boushey said.
