Tropical storm performance monitor page

For each storm day, a series of forecasts from the recent past (up to 120 hours) are plotted along side the observed storm center (based on preliminary position, NOT the best track position) for each storm that has reached depression stage. The tracks are plotted every six hours and the time period between marks are every six hours.

PARX... Various versions of GFS under testing. GFS tracks are plotted every 12 hours and are only available at 00Z
