8/30/2017: Port of Corpus Christi Inner Harbor set to Modified Zulu

The information below was originally posted in a news release issued by the Hurricane Harvey response. To view the original notice, visit the incident news site.

The Coast Guard captain of the port in Corpus Christi implemented Port Condition Modified Zulu for the Port of Corpus Christi Inner Harbor, Tuesday, Aug. 29, 2017.

Modified Zulu for the Port of Corpus Christi Inner Harbor allows tug and barges with drafts not exceeding 20 feet currently in the Inner Harbor to transit freely within the Inner Harbor with no requirements to seek the captain of the port’s permission to move.

Mariners are to proceed with caution as navigational aids may be missing or off station. All other portions of the captain of the port zone remains in Port Condition Zulu unless they have already been cleared by the captain of the port.

Mariners are reminded the Corpus Christi Inner Harbor security zone, 33 CFR 165.809, remains in effect during severe weather. Recreational, commercial fishing and passenger vessels are not permitted to enter the security zone without permission from the captain of the port. Vessels must have prearranged agreements to enter the Inner Harbor as a safe refuge.

“I applaud the incredible work of the Port of Corpus Christi, the Army Corps of Engineers and all industry facilities working hard and collaborating in this process,” said Capt. Tony Hahn, captain of the port of Corpus Christi. “This is a first step but also a very important one towards restoring full capability of the port.”

Please contact (361) 767-2527 with any reports of missing aids to navigation or possible obstruction within the waterways.
