Wednesday and Thanksgiving Day will be warm and wet as a pair of moisture-laden storms barge in from the southwest, prompting warnings about landslides and flooding.
Heavy rain was forecast in a one-two punch of successive storms from Tuesday night through Thanksgiving, adding to the inch of rain that was recorded Sunday and Monday at Bellingham International Airport.
A special weather statement issued Monday warns of increased soil moisture and the possibility of landslides across the interior lowlands of Western Washington, including Whatcom County, according to the National Weather Service.

“We’re going to get a double dose of moisture,” said Ted Buehner, a meteorologist who coordinates weather warnings at the weather service office in Seattle.
Buehner said the storms are carrying warm air and subtropical moisture but aren’t a classic Pineapple Express, which meteorologists call an “atmospheric river.” He said the warm weather will lift snow levels to about 8,000 feet, adding to river runoff.
Temperatures spiked late Tuesday, soaring from the mid-40s to a 61 degrees by 6:30 p.m. and breaking the record of 58 set in 1968, according to National Weather Service records at Bellingham International Airport.
Temperatures are expected in the low 60s Wednesday, which could mean a record high.
“It’s going to be pretty mild,” Buehner said. “Not as mild Thursday, but still well above seasonal norms.”
