Weather information provided by the National Weather Service (NWS) advisories should be used along with __________.

Correct Answer: Option C — weather maps and local knowledge

NWS advisories provide synoptic-scale data, but local conditions are heavily influenced by topography and bathymetry. Combining official forecasts with local knowledge and synoptic weather maps allows the navigator to refine predictions for specific coastal areas, accounting for phenomena that broad-scale models might overlook or generalize.
