SAN FRANCISCO, Jan. 25 (Xinhua) -- Due to foggy weather and new 5G restrictions, several flights were canceled Tuesday morning at the Paine Field Airport near Seattle, the U.S. state of Washington, after all commercial flights out of the airport being canceled on Monday.

Alaska Airlines' regional carrier Horizon Air, the only commercial airline operating out of Paine Field, warned that cancellations could continue for several days.

Due to continued fog, a replacement flight may not be available for the next two to three days, the company said, offering some accommodations to affected travelers, suggesting rebook or cancelation.

"FAA-issued flight restrictions due to the new 5G C-Band signal have limited our ability to land certain aircraft in low visibility," it noted.

The Federal Aviation Administration has imposed limitations on low-visibility flying to avoid 5G interference with cockpit instruments. That has created a problem specific to the Embraer E175 regional jets that operate out of Paine Field, according to a report by The Seattle Times.

The new 5G radio signals turned on last week at cell towers near the airports around the country can potentially interfere with the airplane's altimeter. A false reading could endanger the aircraft.
