Original warning text

1. DUE TO THE APPROACH OF TROPICAL STORM ALBERTO, AIDS TO NAVIGATION
AND STRUCTURES IN THE GULF OF MEXICO MAY BE DAMAGED OR DESTROYED.
LIGHTED AND UNLIGHTED BUOYS MAY MOVE FROM ASSIGNED POSITIONS, BE
DAMAGED, EXTINGUISHED, SINK, OR OTHERWISE MADE INOPERATIVE. MARINERS
SHOULD NOT RELY COMPLETELY UPON THE POSITION OR OPERATION OF AN AID
TO NAVIGATION IN THESE AREAS, BUT SHOULD ALSO EMPLOY SUCH OTHER
METHODS OF DETERMINING POSITION AS MAY BE AVAILABLE. WRECKS AND
SUBMERGED OBSTRUCTIONS MAY MOVE FROM CHARTED LOCATIONS AND PIPELINES
MAY BECOME UNCOVERED OR MOVE DUE TO THE FORCE OF STORM SURGE. STORM
SURGE AND WINDS MAY CREATE SHOALS IN AFFECTED WATERS.  THE U.S. AIDS
TO NAVIGATION SYSTEM MARKING WRECKS AND OBSTRUCTIONS ARE INTENDED FOR
USE WITH NAUTICAL CHARTS.
2. THE EXACT MEANING OF A PARTICULAR AID TO NAVIGATION MAY NOT BE CLEAR
TO THE MARINER UNLESS THE APPROPRIATE NAUTICAL CHART IS CONSULTED.
VIRTUALLY ALL U.S. LATERAL MARKS ARE LOCATED IN IALA REGION B AND
FOLLOW THE TRADITIONAL 3R RULE OF RED, RIGHT, RETURNING. IN U.S.
WATERS, RETURNING FROM SEAWARD AND PROCEEDING TOWARD THE HEAD OF
NAVIGATION IS GENERALLY CONSIDERED AS MOVING WESTERLY ALONG THE
GULF COAST. DRAWBRIDGES MAY DEVIATE FROM NORMAL OPERATING PROCEDURES.
SOME BRIDGES MAY BE UNABLE TO OPEN DUE TO HIGH WINDS. OTHERS MAY BE
AUTHORIZED EXTENDED CLOSED PERIODS TO FACILITATE EVACUATION OF LAND TRAFFIC.
3. MARINERS SHOULD ANTICIPATE BRIDGE CLOSURES BY LISTENING TO THE
NATIONAL WEATHER SERVICE AND COAST GUARD BROADCASTS ON TROPICAL STORM
CONDITIONS. BECAUSE OF THE UNCERTAINTY OF TROPICAL STORM MOVEMENTS AND
BRIDGE CLOSURES, MARINERS ARE URGED TO SEEK SAFE PASSAGE THROUGH
DRAWBRIDGES WELL IN ADVANCE OF THE ARRIVAL OF GALE FORCE WINDS.
LOCKS AND NAVIGATION STRUCTURES WILL BE OPERATED TO PASS NAVIGATION
UNTIL SUCH TIME THAT WATER LEVEL AND WIND CONDITIONS WARRANT OPERATIONS
UNSAFE. THE STRUCTURES WILL THEN BE CLOSED IN ACCORDANCE WITH HURRICANE
PREPAREDNESS PROCEDURES. MARINERS WILL BE GIVEN AS MUCH NOTICE AS
POSSIBLE WHEN STRUCTURES ARE TO BE CLOSED. HOWEVER, THESE STRUCTURES
MAY BE CLOSED ON SHORT NOTICE WELL IN ADVANCE OF THE ACTUAL STORM.
4. MARINERS ARE ADVISED TO SEEK SAFE HARBOR AS SOON AS POSSIBLE.
