NOTE: these trajectories are from https://nomads.ncep.noaa.gov/pub/data/nccf/com/hysplit/prod/traj.YYYYMMDD Time help (UTC=GMT; local)  Updated on Tue Dec 10 04:33:07 UTC 2024txt - Trajectory endpoints format help Forecast DetailsForecast trajectories summarized above come from https://nomads.ncep.noaa.gov/pub/data/nccf/com/hysplit/prod/traj.YYYYMMDD. The 6-h duration forward trajectories begin at the specified number of hours after the start of the meteorological model initialization. The trajectories are computed using meteorological fields output from the NOAA National Centers for Environmental Prediction (NCEP) Global Forecast System (GFS) forecast model. Details on the GFS gridded data used in these calculations are available on the meteorological forecast data web page. Trajectories starting at different heights are shown in different colors. The trajectory endpoints are plotted on maps (gif), displayed in text files (txt), and can be viewed in Google Earth. These are not official forecasts for an eruption and do not show ash fall.
