Vessels resumed moving along the Houston Ship Channel on Tuesday after a 5-1/2 hour halt due to dense sea fog, the U.S. Coast Guard said.

Ship pilots stopped moving ships along the 53-mile (85-kilometer) waterway connecting the busiest U.S. petrochemical port with the Gulf of Mexico at 4:55 a.m. local time (0955 GMT) on Tuesday as sea fog reduced visibility to unsafe levels, the Coast Guard said.

Pilots resumed guiding ships along the channel at 10:30 a.m. local time, according to the Coast Guard.
