Dense fog halted marine pilot service at Texas ports again on Tuesday, a ship agent said.
The Houston Pilots Association, which services vessels entering or departing the port of Houston, resumed boardings for only outbound traffic at 10:45am ET Tuesday after suspending all vessel traffic on Monday evening, the US Coast Guard said.
Pilots also suspended service at the nearby ports of Galveston and Texas City. The port of Freeport, Texas, remained open, the ship agent said.
Pilots halted boardings at the Sabine-Neches Waterway on the Texas-Louisiana border early Tuesday, the third consecutive day with intermittent fog closures. The waterway was last open from 8:30am Monday before closing at 12:30am ET Tuesday.
Vessel traffic resumed at the Louisiana port of Lake Charles at 4:45am ET Tuesday, the ship agent said. Traffic there has been halted every night since 2 February due to dense fog but has remained open during the day.
The October-March period that brings cooler weather to the US Gulf coast also brings periods of dense fog that can disrupt area ports, as warmer humid air collides with colder onshore air masses. Port closures can persist for several days, leading to delays and vessel congestion.
Weather forecasts indicate a moderate to high chance of fog in Texas and Louisiana through Thursday morning.
