Predicting the path of Tropical Storm Erin using spaghetti models typically takes 6-12 hours per forecast update.

Estimated Duration: 12 hours

Spaghetti models, or ensemble forecasts, require running multiple simulations with varying initial conditions to predict storm paths. Meteorologists analyze these models alongside real-time data (satellite, radar, and buoy observations) to refine predictions. The process involves computational time for simulations, expert interpretation, and updates as new data arrives. For Tropical Storm Erin, forecasters typically issue updates every 6-12 hours, depending on the storm's speed and data availability. Accuracy improves closer to landfall as more observations reduce uncertainty.
