This forecast is based on the NWS spot forecast from Wednesday, June 30 PM. Currents were obtained from several models(NOAA Gulf of Mexico, West Florida Shelf/USF, TGLO/TAMU, NAVO/NRL) and HFR measurements. The model wasinitialized from Tuesday-Wednesday satellite imagery analysis (NOAA/NESDIS) and Wednesday overflight observations.The leading edge may contain tarballs that are not readily observable from the imagery (hence not included in the modelinitialization). Oil near bay inlets could be brought into that bay by local tidal currents.

Mississippi Canyon 252Incident Location

Winds are forecast to continue to have an onshore (SE/S) component through next week, withspeeds decreasing from approximately 20 kts Wednesday to 11–14 kts by Saturday. These strongonshore winds will continue to move the northern edge of the slick northwest threatening the barrierislands of Mississippi/Alabama and the Florida Panhandle west of Freeport, FL. The ChandeleurIslands, Breton Sound and the Mississippi Delta also continue to be threatened by shorelinecontacts. To the west of the Delta, these winds may bring oil ashore between Barataria Bay andCaillou Bay – any remaining floating oil may be moved quickly to the west due to the developmentof a strong westward coastal current in this region.

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.
