Plain-English meaning
A separate deductible that may apply when the policy's hurricane trigger is met, often expressed as a percentage.
Why it matters
The out-of-pocket amount can be much larger than the ordinary deductible.
Where you may see it
Declarations, hurricane endorsements, state consumer notices, and renewal documents.
What to verify
Trigger, start and end conditions, percentage base, minimum amount, and interaction with wind or named-storm deductibles.
Do not confuse it with
A wind or named-storm deductible; the triggers may differ.
For policy-specific meaning, read the definition and related provision in the issued policy.
