Question 921Navigation General

The correct answer is A) a weather map. While in port, inspecting a weather map is the best way to follow the approach of a dangerous cyclonic storm. Weather maps provide a visual representation of current and forecasted weather conditions, including the location and movement of storm systems. This information is crucial for mariners to assess the potential impact of a cyclonic storm and take appropriate actions to ensure the safety of their vessel and crew. The other options, while related to maritime operations, do not directly provide the information needed to track the approach of a dangerous storm. The National Weather Service Observing Handbook No.1 and the Coast Pilot or Sailing Directions do not contain real-time weather data, and the sky overhead may not always clearly indicate the presence or movement of a distant storm system.
