Trajectory

Potentialbeached oilX

This forecast is based on the NWS spot forecast from Wednesday, June 23 PM. Currents were obtained from several models(West Florida Shelf/USF, TGLO/TAMU, NAVO/NRL) and HFR measurements. The model was initialized from Wednesdaysatellite imagery analysis (NOAA/NESDIS) and overflight observations. The leading edge may contain tarballs that are notreadily observable from the imagery (hence not included in the model initialization). Oil near bay inlets could be broughtinto that bay by local tidal currents.

Mississippi Canyon 252Incident Location

Moderate SE winds (8-12 kts) are forecast to become E overnight and continue to have an easterlycomponent (E/ESE/ENE) through Saturday. Trajectories indicate westward currents within theMississippi Bight region will inhibit further movement of the slick to the east. Coastal regionsbetween Ship Island, MS and Freeport, FL are threatened by shoreline contacts within this forecastperiod. Under persistent easterly winds, the Chandeleur Islands, Breton Sound and the MississippiDelta are increasingly threatened by shoreline contacts in this forecast period.

The offshore forecast has been temporarily stopped due to smallamounts of oil offshore, the absence of recent observationsconfirming significant amounts of oil in offshore areas, and thelarge separation between the loop current complex and the oilslick. Forecasts will resume if the threat returns.
