    1. Notice to Navigation
    Notice is given that 72 hours prior to a Tropical Storm or Hurricane making local landfall locks will be open 6 AM to 10 PM supporting vessel safe harbor passage. Lock operations will stop 8 hours prior to land fall as Rail Road and drawbridges will be lowered or rotated and locked into a secure position. It’s important that all vessels are at their intended destination before bridges are secured and passage across the waterway suspended.
    For Lock Operator safety the locks will:
    1. Stop locking vessels or working outdoors if lightning is observed within five miles of the lock and
    operations will not resume until lightning has not been seen in the area for 30 minutes.
    2. Stop locking vessels when winds exceed 35 MPH.
    After a storm it could be days or weeks before the waterway is reopen depending on damage to structures and
    how quickly debris creating navigation hazards can be removed.

    FOR IMMEDIATE RELEASE
    Lighting strike affects operations at Canaveral Lock
    A weekend lightning strike at Canaveral Lock will affect boating operations for the early part of this week.
    Operators with the U.S. Army Corps of Engineers Jacksonville District will be operating the lock on a restricted schedule. Locking operations will be conducted at the top of every hour between 6 a.m. and 9 p.m. at the structure, located between the Banana River and Port Canaveral’s west turning basin along Florida’s Space Coast. The Corps suspended operations Sunday afternoon following the lightning strike, but locking was resumed earlier today (July 4) after delivery of a generator.

    “A lightning strike rendered the eastern gate inoperable,” said Candida Bronson, Deputy Operations Division Chief for Jacksonville District. “We moved a portable generator to the site today, and hope to restore the lock to full operations later this week.”
    The Corps advises boaters to plan for potential delays over the next three days, while repairs continue. The Corps finished construction on the lock in 1965 to assist with safe passage from the port to the Atlantic Ocean. It is one of six locks operated by the Jacksonville District. For more information on the district’s lock structures, please visit the following website:

  • Intracoastal Waterway Deepening Project Underway, Fort Lauderdale, FL

    This tax supported dredging to accommodate the yachts of the wealthiest of the wealthy clearly shows to whom Florida politicians bow. You will pay for the project, but will it aid you in any way?

    FLORIDA – AICW – WEST PALM BEACH TO MIAMI – FORT LAUDERDALE: Intracoastal Waterway Deepening Project
    The Florida Inland Navigation District (FIND) is sponsoring a project to deepen the AICW channel to -15 ft MLW in a ±2-mile section from 17th Street Causeway to just north of the Las Olas Bridge. Material from the AICW channel will be mechanically dredged by Cashman Dredging, Inc. and placed into a barge. The material will be dewatered and temporarily placed at a Dredged Material Management Area (DMMA) located at Port Everglades. Dredging will begin the first week of May 2016, and is expected to continue for about 50 weeks. The Dredge CAPTAIN A.J. FOURNIER will work daylight hours only. During the project, every reasonable effort will be made to accommodate normal, safe navigation operations. However, mariners should be aware that clearances within the AICW will be reduced and navigability will be limited during dredge operations. Mariners are urged to subscribe to daily email updates at IWWDredgePosition@jaycashman.com for operation reports and potential impacts to navigation, or call Stephen Tobin (877) 294-9990 or (888) 280-9630 for general questions concerning the project.

  • USCG Hurricane Procedures and Warnings

    Each year around June 1st, the USCG Seventh District publishes detailed information for mariners to heed during a tropical storm event. While these rules and procedures are well known to the savvy sailor, it is good to review before a storm occurs.

    HURRICANE SEASON – JUNE 1st THROUGH NOVEMBER 30th
    Hurricanes can cause excessive damage to vessels and loss of life. To minimize these dangers, the following precautions should be taken by all mariners before getting underway during the hurricane season:
    (a) Instruction of crew and passengers in location of emergency equipment and emergency procedures;
    (b) Pre-sailing check of vessel, machinery, and equipment for seaworthiness;
    (c) Installation of strong ground tackle;
    (d) Review of storm center evasion procedures;
    (e) Knowledge of nearest hurricane shelter or port; and
    (f) Constant radio watches on channel 16 VHF-FM and frequent monitoring of weather broadcasts.
    The civilian hurricane warning service for the North Atlantic is provided by the National Hurricane Center, Miami, Florida. The center collates ship, aircraft, radar, and satellite data to produce and issue tropical cyclone warnings and forecasts for the North Atlantic Ocean, including the Caribbean Sea and the Gulf of Mexico. A Tropical Cyclone Public Advisory (TCP) is issued every six hours, with intermediate bulletins provided as needed. For tropical storms and hurricanes threatening to cross the coast of the U.S., coastal warnings are issued to the public so that precautionary actions, including evacuation, can be initiated to minimize damage and loss of life.
    Four alerts are issued:
    (a) TROPICAL STORM WATCH – An announcement that sustained winds of 34 to 63 knots (39 to 73 mph or 63 to 118 km/hr) are possible within the specified area within 48 hours in association with a tropical, subtropical, or post-tropical cyclone.
    (b) TROPICAL STORM WARNING – An announcement that sustained winds of 34 to 63 knots (39 to 73 mph or 63 to 118 km/hr) are expected somewhere within the specified area within 36 hours in association with a tropical, subtropical, or post-tropical cyclone.
    (c) HURRICANE WATCH – An announcement that sustained winds of 64 knots (74 mph or 119 km/hr) or higher are possible within the specified area in association with a tropical, subtropical, or post-tropical cyclone. Because hurricane preparedness activities become difficult once winds reach tropical storm force, the hurricane watch is issued 48 hours in advance of the anticipated onset of tropical storm force winds.
    (d) HURRICANE WARNING – An announcement that sustained winds of 64 knots (74 mph or 119 km/hr) or higher are expected somewhere within the specified area in association with a tropical, subtropical, or post-tropical cyclone. Because hurricane preparedness activities become difficult once winds reach tropical storm force, the warning is issued 36 hours in advance of the anticipated onset of tropical-storm-force winds.
    The warning can remain in effect when dangerously high water or a combination of dangerously high water and waves continue, even though winds may be less than hurricane force.

    Mariners are reminded that aids to navigation, particularly lighted and unlighted buoys, may be moved from charted position, damaged, destroyed, extinguished, or otherwise deemed discrepant as a result of hurricanes and storms. Mariners should not rely solely upon the position or operation of an aid to navigation, but also employ such other methods of determining position as may be available. Port Hurricane Conditions are set up by the COTP and will change as the threat of severe weather increases, or as a storm approaches a specific COTP Area of Responsibility. For COTP-specific Port Hurricane Conditions, you should review information provided under the Port Directory tab of http://homeport.uscg.mil
    Condition 4 – Hurricane Seasonal Alert. 01 June–30 November; port status: open.
    Condition Whiskey – Sustained Gale Force winds associated with Tropical Cyclone activity are predicted within 72 hours; port status: open.
    Condition X-Ray – Sustained Gale Force winds associated with Tropical Cyclone activity are predicted within 48 hours; port status: open.
    Condition Yankee – Sustained Gale Force winds associated with Tropical Cyclone activity are predicted within 24 hours; port status: restricted; vessel/facility control measures in effect.
    Condition Zulu – Sustained Gale Force winds associated with Tropical Cyclone activity are predicted within 12 hours; port status: closed to all vessel traffic and waterside activities except for activities approved by the COTP.
    Drawbridges along the coast may deviate from normal operating procedures. Drawbridges are authorized to remain closed upon approach of Gale Force winds of 34 knots or greater. Extended closure periods may be authorized up to 8 hours prior to arrival of Gale Force winds to facilitate evacuation of land traffic. Due to the uncertainty of hurricane movements and bridge closures, mariners are urged to seek passage through drawbridges well in advance of the arrival of Gale Force winds.
