Method and sources

Archived NHC operational advisories, most-likely tropical-storm-force wind arrival products, advisory-time 34/50/64 kt wind radii, and NOAA NDFD alert grids are shown only after release. The H-Hour value is a public NHC-derived proxy, not a historical ARC or NHQ H-Hour record.

NDFD surfaces are selected concurrent operational alert evidence. County percentages are app-computed area intersections; they do not imply whole-county coverage or source attribution to the named storm. Short-fuse warning absence does not mean no warning existed.

County height is a transparent planning model based on households, track distance, hurricane risk, and social vulnerability. FEMA Individual Assistance designation is a separate post-event administrative outcome.

The display does not represent observed need, Red Cross caseload, capacity, deployment, or movement.
