Although the practice of dumping munitions into the sea ceased in 1970, a significant amount remains hidden in coastal waters, posing a safety hazard to commercial fisherman, dredge operators, and others who trawl and work the ocean floor. \nRecently, a deckhand on a clamming vessel was severely burned when a canister was dredged up and brought onboard with clams and other debris. The canister likely contained mustard gas or another blistering agent, but did not display any obvious visual, audible, or odor indicators of discharging content. A member of the crew discovered the canister and threw it back overboard. Several hours later he developed a severe rash that required professional medical treatment. \nMustard gas is a chemical weapon developed during World War I. Millions of pounds of this product, other chemical weapons, bombs, torpedoes, artillery shells, and munitions were routinely disposed of and remain in U.S. coastal waters. Although many munition dump areas are well marked on navigation charts, numerous areas where munitions were discarded remain unmarked. There is also evidence suggesting that munitions were frequently “short dumped,” meaning dumped outside of the designated areas by contractors hired to take them to the intended locations. \nThe Coast Guard previously issued Safety Alert 11-16 and Safety Alert 6-10 on this same topic and continues to strongly recommend that persons involved in the fishing and dredging industries: \nReview their navigational charts to ensure the areas in which they are trawling or dredging are not near labeled “Explosives Dumping Areas.” Such areas must be given wide berth and seafarers should recognize that surface bottoms change and that objects can move significant distances from their original disposal areas. \nReview and follow recommendations from the Maritime Industry 3Rs Explosive Safety Guide. \nCarefully record the position of any munitions encountered and returned to the sea. \nImmediately report discovery to the National Response Center, at (800) 424-8802 to ensure a proper response and potential recovery. Alternatively, the local U.S. Coast Guard unit may be notified via VHF-FM Channel 16.

Although the practice of dumping munitions into the sea ceased in 1970, a significant amount remains hidden in coastal waters, posing a safety hazard to commercial fisherman, dredge operators, and others who trawl and work the ocean floor. \nRecently, a deckhand on a clamming vessel was severely burned when a canister was dredged up and brought onboard with clams and other debris. The canister likely contained mustard gas or another blistering agent, but did not display any obvious visual, audible, or odor indicators of discharging content. A member of the crew discovered the canister and threw it back overboard. Several hours later he developed a severe rash that required professional medical treatment. \nMustard gas is a chemical weapon developed during World War I. Millions of pounds of this product, other chemical weapons, bombs, torpedoes, artillery shells, and munitions were routinely disposed of and remain in U.S. coastal waters. Although many munition dump areas are well marked on navigation charts, numerous areas where munitions were discarded remain unmarked. There is also evidence suggesting that munitions were frequently “short dumped,” meaning dumped outside of the designated areas by contractors hired to take them to the intended locations. \nThe Coast Guard previously issued Safety Alert 11-16 and Safety Alert 6-10 on this same topic and continues to strongly recommend that persons involved in the fishing and dredging industries: \nReview their navigational charts to ensure the areas in which they are trawling or dredging are not near labeled “Explosives Dumping Areas.” Such areas must be given wide berth and seafarers should recognize that surface bottoms change and that objects can move significant distances from their original disposal areas. \nReview and follow recommendations from the Maritime Industry 3Rs Explosive Safety Guide. \nCarefully record the position of any munitions encountered and returned to the sea. \nImmediately report discovery to the National Response Center, at (800) 424-8802 to ensure a proper response and potential recovery. Alternatively, the local U.S. Coast Guard unit may be notified via VHF-FM Channel 16.

Due to historical usage of this area, the U.S. Coast Guard advises mariners of potential UXOs located within the Gulf of America and Pensacola Bay, near Santa Rosa Island, Fort Pickens, FL.  UXOs should be considered extremely dangerous.  If touched, moved, or disturbed, these items may detonate, causing severe injury, death, or property damage.  Mariners are strongly urged not to anchor or conduct any bottom-disturbing activities within High Use Areas (HUA) and should exercise caution when conducting activities in the Low Use Areas (LUA). Reference diagrams, provided in the hard copy version of MSIB 32-26, identify Low Use Areas (LUA) in green and High Use Areas (HUA) in orange.

Tropical storms and hurricanes often develop with little warning.  Extensive damage to small craft often results in loss of life.  All mariners, particularly operators of small fishing vessels, are reminded that advanced planning, which may prevent loss of vessel and crew, should include:  \na) Instruction of crew and passengers in location of emergency equipment and emergency procedures.\nb) Pre-sailing check of vessel, machinery, and equipment for seaworthiness.\nc) Installation of strong ground tackle.\nd) Review of storm center evacuation procedures.\ne) Knowledge of the nearest hurricane shelter or port of refuge.\nf) Constant radio watch on VHF-FM Channel 16 and frequent monitoring of VHF-FM Weather Channel for National Weather Service Broadcasts.\n\n\n• AIDS TO NAVIGATION/WRECKS/OBSTRUCTIONS: As a result of tropical storms and hurricanes, aids to navigation along the Gulf Coast and on structures in the Gulf of America and surrounding waters may become damaged or destroyed.  Buoys may move from assigned positions, be damaged, extinguished, sunk, or otherwise made inoperative.  Mariners should not solely rely upon the position or operation of an aid to navigation, but should employ such other available methods of determining positions.  Wrecks, submerged obstructions, and pipelines may move from charted locations or become uncovered due to the force of storm surges.  Storm surges and winds may also create shoals.  The U.S. Aids to Navigation System marking wrecks and obstructions is intended for use with nautical charts.  The exact meaning of a particular aid to navigation may not be clear to the mariner without referencing a nautical chart.  Mariners should exercise caution and report aid to navigation discrepancies and hazards to navigation to the nearest U.S. Coast Guard unit.\n\n• LOCKS/BRIDGES/NAVIGATION STRUCTURES: Drawbridges, locks, and navigation structures along the coast may deviate from normal operating procedures in preparation for heavy weather events.  Some structures may be unable to open because of high winds, high water levels, or to facilitate evacuation of land traffic.  Mariners will be given as much notice as possible when structures are to be closed; however, these structures may close on short notice and well in advance of the storm.  Mariners should anticipate these closures and are urged to seek safe harbor as soon as possible.\n\n• PORTS/WATERWAYS: As tropical weather approaches the Gulf Coast, all potentially affected U.S. Coast Guard Captains of the Port (COTP) will issue a series of Port Conditions to promote the safety of life, the environment, and the viability of the Marine Transportation System.  Port Conditions are issued on a set timeline prior to the arrival of gale force winds associated with a tropical activity and identify the status of the port.  Timelines associated with each port condition are subject to local modifications based upon circumstances, but are most typically issued as follows:\n\n- WHISKEY: 72 hours in advance, OPEN to all commercial traffic. \n- X-RAY: 48 hours in advance, OPEN to all commercial traffic.\n- YANKEE: 24 hours in advance, RESTRICTED with vessel traffic control measures in effect.\n- ZULU: 12 hours in advance, CLOSED to all vessel traffic, except for movements or activities specifically authorized by the COTP.\n\n• Additional requirements or actions to address port-specific safety concerns will be issued by the COTP in conjunction with each Port Condition.  After the passing of a hurricane, local COTPs will issue updates regarding the port status via Broadcast Notice to Mariners and MSIBs.  Mariners are urged to monitor all U.S. Coast Guard and National Weather Service notices and radio traffic closely throughout the Hurricane Season.

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:\n(a) Instruction of crew and passengers in location of emergency equipment and emergency procedures;\n(b) Pre-sailing check of vessel, machinery, and equipment for seaworthiness;\n(c) Installation of strong ground tackle;\n(d) Review of storm center evasion procedures;\n(e) Knowledge of nearest hurricane shelter or port; and\n(f) Constant radio watches on channel 16 VHF-FM and frequent monitoring of weather broadcasts.\n\nThe 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.\n\nFour alerts are issued:\n(a)\tTROPICAL 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.\n\n(b)\tTROPICAL 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.\n\n(c)\tHURRICANE 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.\n\n(d)\tHURRICANE 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.\n\nAdditional information of interest to mariners is included in the Tropical Cyclone Forecast/Advisory (TCM) and the Tropical Cyclone Surface Wind Speed Probabilities (PWS) products. The TCM provides current and forecast storm positions, intensities, and wind fields out to 120 hours. The PWS provides probabilities of sustained wind speeds equal to or exceeding 34-, 50-, and 64-kt wind speed thresholds for select coastal and offshore

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\n\nCondition 4 – Hurricane Seasonal Alert.  01 June–30 November; port status:  open.\nCondition Whiskey – Sustained Gale Force winds associated with Tropical Cyclone activity are predicted within 72 hours; port status:  open.\nCondition X-Ray – Sustained Gale Force winds associated with Tropical Cyclone activity are predicted within 48 hours; port status:  open.\nCondition Yankee – Sustained Gale Force winds associated with Tropical Cyclone activity are predicted within 24 hours; port status:  restricted; vessel/facility control measures in effect.\nCondition 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.\n\nDrawbridges 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.","COORDINATES_JSON":"{\"type\":\"Polygon\",\"coordinates\":[[[-76.76261,7.78362],[-76.77583,8.52376],[-76.02299,9.21256],[-75.52468,9.36733],[-75.41404,10.36809],[-75.16386,10.70491],[-74.82562,10.97866],[-74.33552,10.61997],[-74.06377,11.19191],[-73.22486,11.17338],[-71.66093,12.29659],[-71.3647,12.08774],[-72.09168,11.59235],[-71.63506,10.59633],[-70.04674,11.37269],[-68.88535,11.31252],[-68.53121,11.09018],[-68.20703,10.36977],[-66.28262,10.50084],[-65.87383,10.10614],[-65.09553,9.92567],[-63.04553,10.5602],[-62.89755,10.2609],[-63.0837,9.97785],[-62.56526,9.98809],[-62.21957,9.50807],[-62.0119,9.66005],[-61.69408,9.47181],[-61.55371,9.6954],[-60.78353,9.19771],[-56.99529,9.19779],[-47.9765,9.9524],[-42.86326,12.01631],[-50.8124,18.02749],[-58.44564,23.11607],[-64.95751,26.90697],[-78.29988,33.87179],[-79.58917,34.91981],[-82.3681,35.33412],[-85.66704,35.1195],[-85.33579,32.8239],[-84.16444,32.23767],[-84.06937,31.97938],[-84.90661,30.77318],[-84.86832,30.16198],[-84.23152,30.11469],[-84.23066,29.40955],[-87.23482,21.65027],[-86.94646,21.1498],[-87.87206,19.72117],[-87.67285,19.51678],[-87.83826,18.67727],[-88.08794,18.9957],[-88.44779,18.46805],[-88.22828,18.16412],[-88.43627,16.70265],[-89.05946,15.92405],[-88.14178,15.54737],[-87.67836,15.78133],[-86.37944,15.63403],[-85.9709,15.88484],[-84.32828,15.70211],[-84.15962,15.24173],[-83.37412,15.0004],[-83.55597,14.83498],[-83.34138,14.32599],[-83.6301,13.75221],[-84.00291,11.27492],[-83.52079,10.31608],[-82.4842,9.33402],[-82.34004,8.90728],[-81.12965,8.65389],[-79.59681,9.45594],[-78.98718,9.40946],[-78.10952,9.11105],[-76.76261,7.78362]]]}","COORDINATES_TYPE":"Polygon","DECIMAL_LONGITUDE":null,"DECIMAL_LATITUDE":null}},{"type":"Feature","id":45222,"geometry":{"type":"Polygon","coordinates":[[[-85.83487999999994,24.716420000000028],[-83.97481999999997,29.36946000000006],[-83.98055999999997,30.286020000000065],[-84.64601999999996,30.34021000000007],[-84.64569999999998,30.738290000000063],[-83.78516999999994,31.839110000000062],[-83.95631999999995,32.393080000000054],[-85.09317999999996,32.93805000000003],[-85.55093999999997,35.06085000000007],[-90.33850999999999,35.08257000000003],[-91.32892999999996,33.71456000000006],[-91.25300999999996,33.09541000000007],[-93.94029999999998,33.10964000000007],[-93.99978999999996,33.650990000000036],[-94.36379999999997,33.638810000000035],[-95.19050999999996,34.048460000000034],[-96.35474999999997,33.79036000000008],[-96.96644999999995,34.045660000000055],[-97.89761999999996,33.975340000000074],[-98.06406999999996,34.23599000000007],[-98.48226999999997,34.15701000000007],[-99.11976999999996,34.29254000000003],[-99.34256999999997,34.546020000000055],[-99.67472999999995,34.47734000000003],[-99.89135999999996,34.606610000000046],[-99.96773999999999,36.58588000000003],[-102.89268999999996,36.59141000000005],[-103.00749999999994,37.090190000000064],[-109.15340999999995,37.03501000000006],[-109.09823999999998,31.266680000000065],[-108.16100999999998,31.263510000000053],[-108.09738999999996,31.694810000000075],[-106.45734999999996,31.659110000000055],[-105.01083999999997,30.553060000000073],[-104.58705999999995,29.572290000000066],[-103.30899999999997,28.891040000000032],[-102.78718999999995,29.16628000000003],[-102.58782999999994,29.677340000000072],[-102.30410999999998,29.785180000000025],[-101.44938999999994,29.683920000000057],[-100.76721999999995,29.05564000000004],[-100.35868999999997,28.20312000000007],[-99.61253999999997,27.52594000000005],[-99.54097999999999,26.993660000000034],[-99.18921999999998,26.367530000000045],[-98.22947999999997,25.967710000000068],[-97.70081999999996,25.94658000000004],[-97.39369999999997,25.748380000000054],[-96.79017999999996,25.918480000000045],[-93.41134999999997,25.919710000000066],[-93.04004999999995,26.13921000000005],[-91.40439999999995,25.63400000000007],[-88.38084999999995,25.60883000000007],[-87.39491999999996,25.911500000000046],[-86.59457999999995,26.401830000000075],[-86.28096999999997,26.218890000000044],[-86.64478999999994,25.171950000000038],[-85.83487999999994,24.716420000000028]]]},"properties":{"ESRI_OID":45222,"MSI_UID":45222,"ATU":8,"TITLE":"DISTRICT 8 - CGD-H MSI/General/MSIB","STATUS":"Approved","MSI_GROUP":"General","SUB_CATEGORY":"MSIB","TYPE":null,"WTRW_UID":null,"MRN":null,"WATERWAY_NAME":null,"CREATE_DATE":1780498486000,"MODIFIED_DATE":1780498538000,"BEGIN_DATE":1780444800000,"END_DATE":1830297599000,"DESCRIPTION":"--- MARINE EVENT PERMIT APPLICATION PROCESS MODERNIZATION --- Effective June 3, 2026, the U.S. Coast Guard Navigation Center launched a new online Marine Event Permit application process.
