Methodology, regional deep-dives, and how to read hurricane risk data.
Inland hurricane risk matters because tropical systems can carry damaging wind, rainfall, treefall, and long power disruption well away from the coast. Distance from open water reduces some hazards, yet inland exposure can remain material where storms track repeatedly through the same region.
County hurricane averages miss local wind risk because wind fields, coastal exposure, terrain friction, tree cover, and building-code context vary inside the same county. A county can contain barrier islands, inland towns, and sheltered neighborhoods with different modeled wind histories.
A 1-in-100 hurricane wind estimate is a modeled wind speed with about a 1% chance of being equaled or exceeded in any given year at that location. Multiple exceedances can happen within a century, and long quiet periods can also happen.
Hurricane wind risk estimates damaging wind exposure at a location, while storm surge risk estimates coastal water pushed inland by storm conditions. The two hazards share storms as a source, yet they depend on different geography and property features.
A hurricane risk score summarizes long-run local hurricane exposure on a 0 to 10 scale. Read it with the wind return-period metrics, storm exposure, landfall history, and confidence because coastal distance, track history, and inland wind decay can change the score across nearby places.
