The trajectories shown on this page represent where hypothetical atmospheric releases of material are predicted to be transported. None of the trajectories represent planned or actual releases. Further, the trajectories only indicate the direction of transport of the pollutants and do not include concentrations nor indicate how far significant concentrations would be transported or the height of the pollutants. These trajectories are not appropriate to be used to estimate the impacts of particular planned or actual releases.

Forecast Details

Forecast trajectories for the Gulf of Mexico and vicinity are summarized above. The 18-h duration forward trajectories begin at 11 UTC (6 am EST) today and tomorrow at heights of 10 m, 250 m, 500 m, 1000 m, and 1500 m above model ground level. The trajectories are computed using meteorological fields output from the NOAA National Centers for Environmental Prediction (NCEP) North American Mesoscale (NAM) forecast model. Model output from the latest 00, 06, 12 or 18 UTC NAM forecast are used in the trajectory calculation. Details on the 12 km NAM gridded data used in these calculations are available on the forecast meteorology web page. Trajectories are color coded based on the longitude of the trajectory. The trajectory endpoints are plotted on maps (gif and Google Earth kml/kmz) and displayed in text files (txt).

The trajectories originate at the following locations:
