Pilot Recommendations: Bar Pilots: Recommended maximum loading draft: 50 Feet. Crescent Pilots: Recommended maximum loading draft: 50 Feet. NOBRA Pilots: Recommended loading draft is as follows: 50 feet from New Orleans to Mile 175 ; 47 Feet from Mile 175 - Mile 180; 45 feet from Mile 180 to Mile 234. Vessels with a draft of 41 feet or greater are required to transit the Baton Rouge Harbor (Mile 180 - Mile 234) during daylight hours only.
NOBRA Pilots - High Interest Vessels Vessels classified as HIGH Interest by the Coast Guard, A Federal Authority, Any State Authority, or the NOBRA Board of Directors, may require 2 pilots and be limited to daylight transit only along the NOBRA Route. Any customer of the NOBRA Pilots, docks, berths, moorings, agents, owner, or owner representative may petition the NOBRA Board of Directors to establish or remove the HIV classification.

U.S. Coast Guard Notices: Coast Guard - Hurricane Season 2024 The 2024 Hurricane Season commences June 1st and continues through November 30th. You are strongly encouraged to review your existing hurricane plan or develop a plan if you do not have one. It is extremely important to decide in advance how to minimize your risk and be prepared to evacuate as necessary.
The Captain of the Port (COTP) will set hurricane port conditions in accordance with the Sector New Orleans Maritime Hurricane Contingency Port Plan (MHCPP). The MHCPP is available on the Coast Guard Homeport website https://homeport.uscg.mil/port-directory/new-orleans. This plan describes actions the COTP will take in anticipation of a hurricane or tropical weather conditions, outlines the requirements of each port condition, and includes information regarding vessel movements and mooring requirements during anticipated landfall.
Starting this hurricane season, COTP New Orleans will transition from paper to electronic forms for all MHCPP hurricane reporting forms. Electronic reporting will expedite our ability to gather and distribute time-sensitive information. These electronic forms are for reporting to the COTP New Orleans only and shall not be used for any party or entity in another COTP Zone. All COTP New Orleans MHCPP hurricane forms can be accessed using the QR Code below or at https://linktr.ee/secnolahurricanereporting. Please provide feedback or issues experienced to SecNOLA-WPM@uscg.mil.
Furthermore, the COTP emphasizes the importance of properly maintaining and securing your equipment during hurricane season. Important hurricane-related information will be provided to the maritime community, as needed, through Marine Safety Information Bulletins (MSIBs), Broadcast Notice to Mariners (BNMs), and industry-wide emails.
Regulated Navigation Area (RNA) Annual Hurricane Operation Plans
In accordance with Title 33, Code of Federal Regulations (CFR), Part 165.838, all floating vessels are prohibited from entering or remaining in the Inner Harbor Navigation Canal, Harvey Canal, and Algiers Canal, while the RNA is enforced. However, all facilities that have vessels intending to deviate from the requirements and remain within the RNA during the enforcement period shall develop an Annual Hurricane Operation Plan and provide a copy to the COTP as prescribed within 33 CFR 165.838(e)(1). Guidance outlining the requirements for the Annual Hurricane Operation Plan can be found in enclosure (6) of the Sector New Orleans MHCPP.
Mariner Distress Communications
Mariners are reminded that while operating in the VTS Lower Mississippi River Area, all VTS Users are required under 33 CFR 161.12 (d) to notify the VTS of any marine casualty, pollution incident, defect or discrepancy to an aid to navigation, hazardous condition, improper operation of vessel equipment required by 33 CFR 164, or a hazardous vessel operating condition. A hazardous condition is any condition that may adversely affect the safety of any vessel, bridge, structure, or shore area or the environmental quality of any port, harbor, or navigable waterway of the United States. VTS Users should notify the VTS on VHF Channel 05A, 12, or 67 or via phone at 504-365-2514. Mariners are encouraged to review 33 CFR 161.12 and the VTS LMR user guide to ensure reporting requirements are being met. The VTS LMR User Guide can be found on Homeport at https://homeport.uscg.mil/missions/ports-and-waterways/vessel-traffic-services/vts-lower-mississippi-river/user-guides.

Saltwater Barrier - Mile 64 AHP: The saltwater wedge continues its progression up the river. As of yesterday, the top of the wedge was estimated to be at Mile 49.2 AHP. Construction of the saltwater barrier to 55 feet below the waterline is ongoing and the only restriction to navigation remains one way traffic through the construction site.
The contractor estimates construction to be completed late next week. Once completed the Corps will monitor salinity levels to determine if additional height is needed. If additional height is required, there will be a notch, similar to last year, to allow deep draft traffic to pass through the barrier. Please note that if the additional height is needed, there will probably be two river closures at Mile 63.4, lasting twelve hours each, to allow for construction without having to move equipment for the passage of traffic. As stated above, there will not be a decision of additional height until construction to 55 feet below the waterline is completed and salinity levels are monitored.
Lower Mississippi River Bridges Air-Draft Calculations: The above clearances were calculated this morning using gauge readings provided by the Army Corps of Engineers. As a guide the pilots require at least an additional 3 feet of clearance for the Vessel's Air Draft. The individual pilot assigned to the vessel will make the final determination of the vessel's allowable clearance. Actual clearance should be verified when ordering pilot services.

Weather / Marine Zone Forecast
U.S. Corps of Engineers: VELOCITY READING (NEW ORLEANS) -1.3 Knots Mississippi River - Projection- Based off 48 Hours of Forecast Rainfall Mississippi River - NOLA Projection- Based off 16 Days of Forecast Rainfall (Experimental)-
Lower Mississippi River Forecast Center Advisory - 09/18/2024 This week we are expecting minimal rainfall in the Ohio and Lower Mississippi River Valleys, with an inch at the highest and many locations remaining dry. However there is expected to be a broad swath of 2+ inches of rain from central Kansas to northwest Wisconsin.
Cairo stages are seeing minor fluctuations with peaking from Barkley/Kentucky dams but look to drop below 8.0 feet by the weekend and continue a gradual recession to base level low stages.
Our official forecast with 48 hour forecasted rainfall and longer range outlook with 16-days of future forecast rainfall are still not picking up on any significant additional rainfall over the next two weeks that will slow recessions.
Stages on the lower end of the Mississippi below Baton Rouge will continue to be moderated by winds and tides.
The Climate Prediction Center outlooks for the 8-14 day, one month and three month outlooks are calling for Normal to Below Normal conditions over the Ohio and Upper Mississippi.
