How Hurricanes Move Gas Prices — and When They Don't
The Gulf Coast holds roughly half of U.S. refining capacity. How a hurricane adds 20 to 50 cents — and why some storms move prices while others do not.
Hurricane season runs from June 1 to November 30. Every year, forecasters warn about supply disruptions, and every year some storms move prices while others do not. The difference is not wind speed — it is which infrastructure the storm hits.
The concentration problem
The U.S. refining system is geographically concentrated:
- The Gulf Coast (Texas, Louisiana, Mississippi, Alabama) holds roughly half of U.S. refining capacity.
- The largest cluster runs from Corpus Christi through Houston, Port Arthur, and Lake Charles.
- A significant share of the nation’s pipeline and terminal infrastructure sits in the same corridor.
When a hurricane threatens that corridor, refiners shut down units and evacuate workers. A refinery shutdown is not instantaneous to reverse: restarting a large refinery can take days to weeks, and damaged units can take months.
The supply chain that breaks
A hurricane can disrupt five separate links:
1. Refineries
Precautionary shutdowns begin 48 to 72 hours before landfall. A refinery that shuts down safely can restart in days; one that floods or loses power may be offline for weeks.
2. Ports
The Gulf ports handle crude imports and refined product exports. Port closures prevent crude from arriving and product from leaving, which backs up the entire system.
3. Pipelines
Pipelines that move gasoline from the Gulf to the Midwest and East Coast may lose power or be shut down as a precaution. Pipeline outages spread the impact far beyond the storm’s path.
4. Terminals and storage
Terminals that flood or lose power cannot load trucks, which stops deliveries to stations even if the refinery is fine.
5. Retail logistics
Trucking to stations depends on roads, fuel for the trucks, and electricity at the station. Flooded roads and power outages can leave stations dry even when supply exists.
Why prices rise before landfall
Markets are forward-looking. As soon as a forecast track threatens the refining corridor:
- Refiners buy replacement supply or reduce commitments.
- Traders bid up wholesale gasoline futures.
- Stations begin raising prices in anticipation of higher replacement costs.
The national average often rises 5 to 15 cents before the storm arrives, then more if damage is severe. This is the market pricing risk, not a conspiracy.
Historical examples
Hurricane Katrina (2005): Shut down most Gulf refining and the New Orleans port complex. The national average rose above $3 for the first time, from about $2.30 before the storm.
Hurricane Harvey (2017): Dropped more than 50 inches of rain on the Houston area and shut down a large share of Gulf refining for weeks. Wholesale prices spiked and retail followed.
Hurricane Ida (2021): Shut down offshore production and Gulf refineries, contributing to a price increase that coincided with other supply tightness.
Storms that miss: Many named storms each year have no measurable price impact because they miss the refining corridor or cause only brief precautionary shutdowns.
What actually determines the price impact
- Track relative to the refining corridor. A storm hitting the Texas-Louisiana coast matters far more than one hitting Florida.
- Duration of shutdowns. A three-day precautionary shutdown is absorbed; a three-week outage is not.
- Damage to power infrastructure. Refineries need electricity; widespread grid damage extends outages.
- Concurrent refinery maintenance. A storm during already-tight maintenance season is worse.
- National inventory levels. High inventories buffer the shock; low inventories amplify it.
What drivers should do
- Fill up before landfall if you are in the storm’s path or in a region supplied from the Gulf.
- Do not hoard. Panic buying creates local shortages faster than the storm does.
- Expect price spikes to be temporary unless the damage is severe. Prices usually fall back within weeks as refineries restart.
- Check the state average rather than the national news. The impact is regional, not uniform.
- Avoid price gouging reports without evidence. Most stations are passing through replacement costs, though some do take advantage.
The current situation
As of the week ending October 26, 2026, the national average is $4.269. There is no active supply disruption in the data, and the seasonal switch back to winter blend is complete. If a storm enters the Gulf in the coming weeks, expect the usual pattern: a pre-landfall increase, then a decline as refineries restart.

Frequently asked questions
Do hurricanes always raise gas prices?
No. Prices rise when a storm forces refinery shutdowns, port closures, or pipeline outages for an extended period. A storm that misses the refining corridor or causes minor damage can have almost no effect.
How much do gas prices rise after a hurricane?
A major hurricane that shuts down Gulf Coast refining for a week or more can add 20 to 50 cents per gallon nationally within days. Regional increases near the affected area can be larger.
Why do prices rise before the hurricane makes landfall?
Markets price in expected supply loss. Refiners begin shutting down units and evacuating personnel days before landfall, and traders bid up wholesale gasoline as soon as the forecast track threatens the refining corridor.
Should I fill up before a hurricane?
Yes, if you are in the path or in a region supplied by Gulf Coast refineries. Fill up early, but do not hoard fuel in unsafe containers. Panic buying creates shortages that would not otherwise occur.
