PORT CONDITION WHISKEY

At 1400 EST on July 31, 2020 Coast Guard Captain of the Port (COTP) Charleston, South

Carolina set Port Condition WHISKEY for coastal South Carolina. Threatening winds (34 kts/39

mph) from Hurricane Isaias are possible along the coast of South Carolina within 72 hours.

All oceangoing commercial vessels and oceangoing barges greater than 500 gross tons are to

review plans for departing the port 24 hours prior to the storm’s arrival. Vessels unable to depart

within this timeframe must immediately contact Coast Guard Sector Charleston and submit a

written safe mooring plan to be reviewed and accepted by the COTP. Vessels bound for this port,

which are unable to depart 24 hours prior to threatening winds making landfall, are advised to seek

an alternate destination.

Pleasure craft are advised to seek safe harbor. Commercial vessel operators authorized by the

COTP to remain inside Sector Charleston’s harbors, and recreational boat owners, should ensure

their vessels are secure at berth and will not pose a hazard to surrounding vessels, the navigable

channel, or the environment. Mariners are reminded that drawbridges may not operate when

sustained wind speeds reach 25 mph or when an evacuation is in progress.

Facilities are advised to review their heavy weather plan and take all necessary precautions to

adequately prepare for the forecasted conditions.
