Hurricane season (June 1 – November 30) is an operational fact of life for South Florida shippers. The playbook that works: build inventory buffers before peak season, know the port condition system, pre-arrange storm-rated warehousing, and lock a recovery plan with your carriers before a storm is named. Shippers who wait until the cone appears are competing with everyone else for the same trucks and dock doors.
How ports and airports shut down
PortMiami and Port Everglades follow the Coast Guard’s port condition sequence: WHISKEY (72 hours from gale-force winds), X-RAY (48), YANKEE (24 — inbound traffic stops), and ZULU (12 — port closed). Terminals stop accepting export loads and stack operations well before ZULU, and vessel schedules slide for days after reopening. MIA cargo operations follow a similar curve. Practical translation: your last reliable gate day is usually 2–3 days before landfall, and the first normal day is 2–5 days after — a week-long hole in the supply chain from a single storm.
Before the season: structural moves
Carry 2–3 extra weeks of safety stock on storm-critical SKUs from August through October. Verify your warehouse’s wind rating, flood zone, and backup power — and whether your inventory insurance covers named storms or carries a separate deductible. Diversify: if you fulfill only from South Florida, a partner node in Orlando or Atlanta keeps e-commerce alive during a closure. Review force majeure clauses in carrier contracts so post-storm surcharges don’t surprise you.
When a storm is named: the 96-hour checklist
Pull import containers off port early — terminals waive nothing during a scramble, and pre-pulled boxes sit safe in a yard instead of a stack (see what a pre-pull is). Accelerate outbound loads to beat gate cutoffs. Top off fuel for gensets and yard equipment. Confirm reefer plugs and generator capacity for temperature-controlled inventory. Then stop trucks early — driver safety beats one more load, and expedited freight can recover the backlog afterward.
After the storm: recovery sequencing
Reopening is congestion season: every importer wants the same drayage capacity the day the port reopens. Carriers prioritize customers with standing volume and pre-agreed recovery plans. Route optimization matters more than ever while signals are dark and roads are partially closed — our piece on real-time route optimization in South Florida shows how dynamic routing recovers hours per day.
How Go Freight rides out storms
Go Freight’s 104,000 sq ft Miami warehouse runs backup power with a hurricane-rated structure outside the highest-risk flood zones, and our 100+ owned trucks and chassis pool let us pre-pull customer containers before closures and surge capacity after reopening — coordinated through our warehouse operation and DispatchAI.
Frequently asked questions
How far in advance do Miami ports close before a hurricane?
Inbound vessel traffic typically stops about 24 hours before gale-force winds (Port Condition YANKEE), but terminal gates restrict operations one to two days earlier, so plan final pickups 2–3 days before forecast landfall.
Should I pull my containers off port before a storm?
Usually yes. A pre-pulled container in a secured, elevated yard avoids both storm exposure in the stacks and the post-storm gate congestion, and it stops the demurrage clock issues that follow extended closures.
Does cargo insurance cover hurricane damage?
Marine cargo policies generally cover named-storm damage in transit, but warehouse inventory often falls under separate property coverage with named-storm deductibles. Verify both before June.
