This report summarizes and interprets tidal current and oil spill trajectory predictions obtained from a computer model of the Strait of Juan de Fuca and regional wind fields derived from a computer model of the entire Puget Basin. The meteorology of the Puget Sound Basin is discussed with respect to three dominant weather patterns which were subsequently used to run the regional meteorological model. These model results are incorporated into oil spill trajectory calculations as large scale wind fields over the Straits which are sequentially keyed by baric types for any given modeling period. A sea breeze condition was also considered and is described in the trajectory modeling section. The oceanography of the Strait of Juan de Fuca region is presented as a discussion of the dominant features, tidal and estuarine flow components, and some possible deviations from these main elements. The tide subroutines constructed for the trajectory model are based on empirical data from NOS tidal current stations and are inline functions to the trajectory model. The principal product of the model was a series of simulated oil spill trajectories.
