What this tool does

Measure your distance from an official active storm and understand the published hazard context.

Method

Official storm products are combined with user-selected coarse coordinates; geodesic distance is calculated locally and forecast uncertainty remains visible.

Example

Select an active Atlantic storm and Santo Domingo to see its current distance, movement, official advisories, and when to pay attention.
