Hurricane Hilary, currently in the eastern Pacific off the coast of Mexico, could produce wet conditions that will affect Sunday’s racing program at Del Mar. Weather forecasters are predicting the storm will advance north through Baja California and could bring widespread rain to the southwest of the United States, including Southern California. The storm could arrive Sunday afternoon, although many forecasts expect more significant rain on Monday.
