Call the track.

You get the snapshot a specialist would have had — position, intensity, recent motion, a few lines of environment. You do not get the name. Five clicks. Five days. Then we open the best track.

1. Place 24 / 48 / 72 / 96 / 120-hour positions on the map. Drag to adjust.

2. Call a peak intensity. Persist is the lazy forecast — a straight line at the current heading.

3. We score you in nautical miles against the NHC best track, next to typical NHC error at each lead.

Call against the live desk.

Place a track before you look at Helix or the NHC official. We score you against the official if it exists, otherwise against Helix. The storm is still out there — this is not verification.
