Named Storm Deductible
A separate deductible that applies only to losses caused by a storm that has been officially named by the National Hurricane Center or a similar meteorological authority. Typically expressed as a percentage of the dwelling coverage.
A named storm deductible is a separate, usually percentage-based deductible that applies only to damage caused by a storm that has been officially named by a meteorological authority such as the National Hurricane Center. It is most common in coastal states exposed to hurricanes and tropical systems.
How It Is Triggered
The trigger is the naming of the storm, not its strength. A tropical storm, subtropical storm, or hurricane that has been assigned a name by the National Hurricane Center activates the deductible. Each carrier specifies in policy language how long before and after landfall the trigger applies, often spanning from the storm naming through 24 to 72 hours after dissipation in the region.
How Much It Costs the Insured
Named storm deductibles are usually percentage-based, ranging from 1 percent to 10 percent of the dwelling coverage depending on the state and the carrier. On a $400,000 dwelling with a 5 percent named storm deductible, a hurricane-caused loss carries a $20,000 deductible before coverage starts. Contractors filing claims after a named storm should confirm the deductible structure with the insured before building the estimate, because the math looks very different from a flat deductible.
Documentation Requirements
Because coverage turns on whether the storm was named at the time of loss, carriers scrutinize the date of loss carefully. NOAA advisories, National Weather Service reports, and local news coverage establishing the timing of the named storm support the claim. Damage that occurred outside the named-storm window may be covered under the standard wind deductible instead.
Frequently asked questions
It applies when the loss is caused by a storm the National Hurricane Center has officially named. Policies differ in how they define the trigger window, but generally the storm must be named at the time damage occurs, not later reclassified.
They overlap but differ. Hurricane deductibles typically trigger only when a storm reaches hurricane strength. Named storm deductibles trigger on any named storm, including tropical storms that have been named but not yet classified as hurricanes. Named storm is generally broader.
Named storms cause widespread catastrophic losses across entire regions. Carriers use higher deductibles to share more of the risk with policyholders in hurricane-prone states. It is a pricing mechanism for catastrophe exposure, not a penalty.
