Atlantic Hurricane Season 2026: Port Shutdowns, Omitted Calls and Surcharges on the US East Coast, Gulf and Caribbean - What Shippers Need to Know

The 2026 Atlantic hurricane season runs from 1 June through 30 November, with the statistical peak concentrated between mid-August and mid-October. For freight forwarders and shippers with cargo moving to or from US East Coast ports, Gulf Coast facilities, or Caribbean transshipment hubs, this six-month window represents one of the most operationally complex periods of the year. Unlike most other trade disruptions, hurricanes introduce simultaneous risk at both the port level and across inland distribution networks - closing terminals, triggering carrier omitted calls, driving surcharge accumulation, and creating multi-week backlogs that affect cargo well beyond the storm's direct path.

This guide covers which ports and trade lanes face the highest exposure during the 2026 season, how port closures and omitted calls operate in practice, what surcharges shippers should anticipate, and how to structure pre-season planning to protect your supply chain.

Why Hurricane Season Is One of the Most Disruptive Events for Ocean Freight

How Tropical Storms Translate into Operational Port Closures

When a named tropical storm or hurricane approaches a US coastal port, port authorities typically issue a sequence of operational protocols that escalate as the storm track becomes clearer. The first stage involves the suspension of hazardous cargo operations and the inspection of all vessels at berth. As a storm reaches Category 1 intensity or higher and a watch or warning is issued for the port area, full port closure is typically ordered: terminal gates close, crane operations cease, vessels are ordered to sea to avoid surge damage, and customs and administrative functions are suspended.

The closure is not limited to the physical terminal. Coast Guard vessel traffic services issue port condition statuses - ZULU, YANKEE, X-RAY, WHISKEY, INDIA, and NOVEMBER - that govern vessel movement. A port condition of X-RAY or lower effectively prevents all cargo vessel arrivals and departures. Unlike a scheduled holiday closure, storm closures are issued with short notice, typically 24 to 72 hours ahead of the storm, making it difficult to divert or reroute cargo that is already at sea.

The Scale of Trade Routes at Risk

The US Gulf Coast and East Coast collectively handle a significant share of the country's containerised import and export traffic. The Port of Houston is the largest port in the Gulf and a critical gateway for petrochemical exports and Asian imports. Ports along the US East Coast from Jacksonville to Savannah and Charleston to New York handle major volumes across transatlantic and transpacific trade lanes. Caribbean hubs including Kingston, Freeport, and Caucedo serve as key transshipment nodes connecting Asia-origin cargo with final destinations across Central America, the Caribbean Basin, and parts of South America.

A single major hurricane affecting the Gulf Coast or Caribbean can simultaneously close or reduce capacity at multiple ports, disrupt transshipment schedules, and strand cargo at sea. When the storm's track is uncertain, carriers begin adjusting vessel rotations days before landfall, meaning the operational impact begins well before the storm itself arrives.

Why the 2026 Season Forecast Matters for Your Booking Calendar

NOAA and other meteorological agencies issue pre-season forecasts that indicate the likely number of named storms, hurricanes, and major hurricanes for the season. An above-normal forecast - driven by factors including sea surface temperatures and the absence of El Nino conditions - increases the statistical probability of landfalling storms affecting commercial ports. Shippers planning FCL and LCL bookings for the June-to-November window should factor forecast severity into their inventory build and booking cut-off decisions, particularly for cargo routing through Gulf and Caribbean ports where storm frequency is highest.

Which Ports and Regions Are Most Exposed

The table below summarises the primary port clusters at risk during the 2026 season, their typical closure durations based on historical patterns, and their recovery timelines.

US Gulf Coast: Houston, New Orleans, Mobile and Tampa

The US Gulf Coast sees the highest frequency of hurricane landfalls of any US coastal region. The Port of Houston (Barbours Cut and Bayport terminals) serves as the country's leading container port by tonnage and a critical export gateway for agricultural products and manufactured goods. New Orleans and the surrounding Port NOLA complex handle significant import volumes. Tampa, while smaller in container terms, is a key hub for regional distribution. During a Gulf Coast storm, the Houston Ship Channel is typically closed 24 to 72 hours prior to landfall and may remain closed for several days post-storm as debris clearance and vessel inspections are completed.

US East Coast: Miami, Savannah, Charleston and Jacksonville

East Coast ports face primarily indirect exposure to Gulf storms and direct exposure to storms tracking up the Atlantic seaboard. The Port of Savannah is the third-busiest container port in the US and a critical inland distribution point for the southeast. Miami and Port Everglades together handle the majority of Caribbean trade flows. During major East Coast storms, port closures of 24 to 48 hours are common, with post-storm recovery times of three to seven days depending on storm intensity and the extent of infrastructure damage.

Caribbean Transshipment Hubs: Kingston, Freeport and Caucedo

Caribbean transshipment hubs are disproportionately exposed to hurricane disruption given their geographic position in the primary storm track. Kingston, Jamaica, and Freeport, Bahamas, are among the busiest transshipment ports in the region and serve as relay points for cargo moving between Asia and Central and South American markets. A direct hurricane hit on Kingston or Freeport can create multi-week disruptions to transshipment schedules, with cascading effects on feeder vessel services and on-carriage to final destinations. Shippers with cargo moving through these hubs during peak storm season should build contingency lead times of at least two to three weeks.

Mexico and Central America: Veracruz, Manzanillo and Puerto Cortes

While Mexico's Pacific coast ports such as Manzanillo face Pacific storm exposure, the Gulf of Mexico coast including Veracruz is within the Atlantic hurricane belt. Central American ports including Puerto Cortes in Honduras and Puerto Quetzal in Guatemala can be affected by storms tracking through the Caribbean and into Central America. These ports are important for both import distribution and for agricultural exports. Disruptions at these facilities often have compound effects on US-bound supply chains where Central American origin cargo transships through Caribbean hubs.

What Actually Gets Disrupted - and for How Long

The table below summarises the principal disruption types, their triggers, and their operational impacts on cargo in transit.

Port Closures and Vessel Diversions

A port closure during a hurricane is a cascading event. When a port authority issues a closure order, vessels already in port or approaching are ordered to sea. This creates vessel bunching at anchorage positions offshore, meaning that when the port reopens, multiple vessels attempt to berth within a compressed window. The result is a multi-day queuing situation that can delay cargo discharge by three to seven days beyond the port's reopening date. Simultaneously, vessels that were diverted mid-voyage to avoid the storm's track may have called at alternative ports, meaning cargo intended for the affected port is now sitting at a different facility and requires onward trucking or rebooking.

Omitted Calls: Why Carriers Skip Ports and What That Means for Your Cargo

An omitted call occurs when a carrier announces that a specific port will not be included in a vessel's rotation, either due to storm risk, reduced port capacity, or schedule recovery following a prior disruption. Omitted calls are among the most commercially disruptive events for shippers, because cargo booked on that vessel for that port is either held on the vessel to the next available port of call, rolled to the following vessel on the same service, or transferred to a different service entirely.

Carriers typically provide 24 to 72 hours' notice of an omitted call. Shippers and forwarders should monitor carrier advisories closely during the June-to-November window and ensure they have contingency arrangements in place for cargo at sea during a named storm event. The right to omit calls in force majeure circumstances is typically written into standard carrier bills of lading, limiting the shipper's ability to claim compensation for delay costs.

Inland Disruptions: Road, Rail and Intermodal After Landfall

The impact of a major hurricane does not stop at the port gate. Storms that make landfall bring sustained winds, storm surge, and flooding that can close highways, damage rail infrastructure, and disable intermodal yards for days to weeks. In the aftermath of Hurricane Harvey in 2017, major road and rail corridors in the Houston area were closed for several weeks, preventing cargo from reaching or leaving the port even after terminal operations resumed. Shippers relying on drayage from Gulf ports to inland distribution centres should plan for last-mile delays of three to ten days following a major landfall event.

The Post-Storm Backlog: How Long Does It Take to Normalise?

Port recovery timelines following a major hurricane vary significantly based on storm intensity, storm surge levels, and the extent of infrastructure damage. Following a direct hit from a Category 3 or above storm, full operational normalisation at a major container terminal can take two to four weeks. Even in cases where the port itself sustains minimal damage, the accumulation of vessels at anchorage, the backlog of customs processing, and the shortage of available drayage equipment and drivers creates a multi-week congestion period that affects all cargo moving through the facility.

Hurricane Surcharges Explained: What Carriers Charge and Why

The table below sets out the principal surcharge types shippers can expect during the hurricane season, along with typical ranges and the parties that apply them.

Emergency Port Surcharges (EPS) and When They Apply

Emergency Port Surcharges are levied by ocean carriers when a named tropical storm or hurricane threatens or impacts a port in their rotation. EPS charges are applied per container and are typically announced with 72 hours' notice. They are intended to cover the carrier's additional costs associated with vessel diversions, port re-entry delays, and the handling of disrupted schedules. EPS charges are not negotiable in most cases and apply regardless of whether the cargo is actually affected by the storm. Shippers with long-term service contracts should review their agreements to understand whether EPS charges are covered or excluded under existing rate provisions.

Congestion Surcharges Post-Storm

Following a major port closure, the accumulation of vessels waiting to berth and the backlog of containers awaiting discharge creates significant terminal congestion. Carriers and terminal operators may apply congestion surcharges to recover the additional costs of extended vessel dwell time and overtime operations required to clear the backlog. These surcharges are applied on a per-container basis and typically remain in force until the terminal returns to standard throughput levels, which may take two to four weeks after a significant storm event.

Omission and Deviation Fees

When a carrier omits a port call or deviates a vessel to an alternative routing, additional fees may apply for cargo affected by the change. Where cargo is held on a vessel to a subsequent port of call, the carrier may charge a transshipment or re-routing fee for onward delivery to the original destination. These fees are typically outlined in the carrier's tariff and their applicability in storm situations should be confirmed with the carrier's commercial team at the point of booking.

Cargo Insurance and Hurricane Season: Gaps Shippers Often Miss

Standard marine cargo insurance policies cover physical loss or damage to cargo during transit, but do not typically cover delay-related costs such as demurrage, detention, or lost sales caused by storm disruption. Shippers moving high-value or time-sensitive cargo through Gulf or Caribbean routes during peak storm season should review their insurance policies to understand whether delay coverage can be added as an endorsement. Additionally, cargo stored at a port facility at the time of a major storm may be subject to coverage exclusions if the cargo was not in transit at the point of loss.

Which Cargo Types and Trade Lanes Face the Highest Risk

Asia-US Gulf and East Coast Imports

Asia-to-US Gulf trade lanes carry some of the highest volumes of containerised manufactured goods, electronics, furniture, and retail inventory moving into the US market. Cargo departing major Chinese ports on standard transit times of 25 to 35 days to Gulf ports is highly susceptible to arriving during an active storm window if bookings are not timed carefully. The challenge for shippers on this lane is that booking decisions must be made three to five weeks before arrival, at a point when storm tracks are inherently uncertain. Building buffer time into booking windows and working with carriers who offer flexible rerouting options is the most effective risk mitigation strategy for this lane.

Europe-US Gulf and East Coast Exports

European exporters shipping to US Gulf and East Coast ports via the North Atlantic typically work with transit times of 12 to 18 days. Cargo leaving European ports in August or September is at risk of arriving during the peak storm window. This is particularly relevant for capital goods, automotive parts, and high-value consumer products shipped ahead of the autumn retail season. Freight forwarders handling European exports to the US should communicate revised cut-off and ETA guidance to shippers no later than six weeks before intended vessel departure.

Perishables, Project Cargo and Time-Sensitive Shipments

Perishable cargo moving through Gulf or Caribbean ports during hurricane season faces compounded risks. A port closure of even 48 to 72 hours can compromise cold chain integrity for temperature-sensitive goods if reefer power is disrupted at the terminal. Project cargo with fixed installation schedules, construction materials tied to weather-dependent site timelines, and just-in-time industrial components are all particularly vulnerable to the multi-week delays that follow a major storm event. Shippers of these cargo types should work with their forwarders to identify alternative routing options and to build stock buffers where possible ahead of peak storm season.

How to Plan Your Shipments Around the 2026 Hurricane Season

The table below provides indicative booking windows for the principal trade lanes at risk during the 2026 season.

Revised Cut-Off Dates: FCL and LCL Booking Windows

For FCL shipments destined for US Gulf or East Coast ports, shippers should aim to either complete delivery before the mid-August peak window or to book sufficiently late that arrival is expected after mid-October. For LCL shipments, origin consolidation cut-offs are typically three to five days earlier than the FCL equivalent on the same trade lane. Shippers booking LCL cargo for Gulf or Caribbean destinations during August and September should confirm cut-off dates with their consolidator at least four weeks in advance.

Rerouting Options When Gulf or East Coast Ports Are Affected

When a Gulf Coast port closes ahead of a storm, a limited set of rerouting alternatives exist. Cargo destined for Houston can in some cases be rerouted to Gulf of Mexico feeder ports or to East Coast alternatives with onward rail or truck movement inland. Caribbean transshipment cargo may be able to route via alternative hubs such as Cartagena, Colombia, or via Panama Canal services that avoid the affected port. For time-sensitive cargo, air freight from origin to an unaffected airport with onward trucking may be viable, though air freight capacity to US Gulf destinations tightens significantly during storm season as demand increases.

How to Monitor Storm Tracks and Carrier Advisories in Real Time

During active storm season, shippers and forwarders should monitor NOAA's National Hurricane Center (nhc.noaa.gov) for official forecast tracks and port condition updates. All major carriers publish operational advisories on their websites when port conditions change; forwarders should subscribe to carrier advisory mailing lists for all carriers operating on their active lanes. Port authority websites for major Gulf and East Coast facilities publish port condition status updates that indicate when closures are imminent.

Communicating Delays to Customers and Suppliers

Proactive communication with consignees and suppliers during hurricane season is essential to avoid compounded disruption. Consignees who are not informed of a port closure may schedule drayage or warehouse receiving during a period when cargo will not be available. Suppliers in Asia who are not aware of adjusted booking windows may dispatch cargo on standard timelines that result in arrival during a storm window. Freight forwarders handling US Gulf and Caribbean-routed cargo should issue hurricane season advisory notices to all affected stakeholders at the start of the season in June and update them with specific shipment guidance when named storms are forecast.

Pre-Season Checklist for Freight Forwarders and Shippers

• Identify all active and planned shipments with US Gulf, East Coast, or Caribbean routing scheduled for arrival between June and November 2026.
• Subscribe to NOAA National Hurricane Center advisories and carrier operational alert mailing lists for all carriers on active lanes.
• Review all carrier bills of lading for force majeure and omitted call provisions and confirm what fees apply in storm scenarios.
• Confirm revised FCL and LCL cut-off dates with carrier and consolidator partners for peak storm season bookings.
• Review cargo insurance policies for storm-related coverage gaps, particularly regarding delay costs and reefer cargo exposure.
• Issue pre-season advisory notices to all consignees and suppliers with active or planned Gulf and Caribbean-routed shipments.
• Identify alternative routing options and air freight backup plans for time-sensitive or perishable cargo on vulnerable trade lanes.
• Calculate demurrage and detention exposure for any cargo scheduled to arrive during August to October and confirm free day entitlements.
