Put your mouse over to choose the appropriate time :

* For best results, please use at least the following resolution : 1152*864

* Be aware, especially for the current information, that the grid points are the arrow's bases.

* Please compare results with the methods you currently use to predict wave conditions at the entrance bar, and provide feedback on your findings to Troy Nicolini or Greg Crawford at the numbers below. Also, remember to listen to NOAA weather radio for the most up to date coastal marine forecast and the U.S. Coast Guard broadcast on VHF radio.

* IMPORTANT NOTE: The bar forecast does not always identify hazards when they occur outside the jetties - because of rapid bar formation at the tip of the south jetty, and because of complex interactions between tidal current and general ocean current. Therefore, do not assume that the lack of hazard delineation in this area indicates the waves are not hazardous.

Please provide feedback regarding the usefulness of the bar forecasts to Troy Nicolini or Greg Crawford. Contact information is listed below.
