The National Ocean Service (NOS) has developed an experimental nowcast/forecast system in conjunction with its Physical Oceanographic Real Time System (PORTS) for Galveston Bay. Both a Bay model and a one-way coupled, fine resolution Houston Ship Channel model (Schmalz, 1998) based on the Mellor-Blumberg (1987) three-dimensional sigma coordinate formulation have been used to provide daily 24 hour nowcasts and 36 hour forecasts for water levels, currents, salinity, and temperature on an experimental basis over the past three years.
