Hurricane TrackerEvery storm, live, minus the jargon
2 storms on the board. Trudy is the one to watch: Tropical storm, 46 mph and getting stronger, forecast to peak near 132 mph (Category 4).
How to read the map: white cones are where each center will probably go, not how big the storm is. The track changes color with the forecast strength. Colored coastlines are watches and warnings. Source: National Hurricane Center.

Quick questions
Is there a hurricane right now?
Yes. The National Hurricane Center is tracking 2 tropical cyclones right now: 1 hurricane and 1 weaker system.
Where does this data come from?
Straight from the National Hurricane Center (NOAA). U.S. alerts come from the National Weather Service and the humanitarian alert level from GDACS. We don't forecast anything ourselves; we just draw their forecasts so they're easier to read.
How often is it updated?
The NHC publishes a full advisory every six hours (5 and 11, AM and PM, local time), plus extra ones every three hours when warnings are up. We check for new ones every 30 minutes.
What is the cone of uncertainty?
It's where the center will probably go, not how big the storm is. The center stays inside it about two times out of three, and wind, rain and surge regularly spill far past the edges. Being outside the cone is not an all-clear.
What are spaghetti models?
Each line is one computer model's guess at the track. Lines bunched together: the models agree. Lines all over the place: nobody is sure yet. The official NHC forecast weighs them all, plus a forecaster's judgment.
