How often does the National Weather Service (NWS) provide weather forecasts and warnings for mariners?

The National Weather Service (NWS) provides weather forecasts and warnings specifically for mariners four times a day. This frequency ensures that sailors and other maritime operators receive timely and relevant information about weather conditions that could affect their safety and navigation on the water. The routine issuance of forecasts and warnings is crucial for mariners, as weather can change rapidly and have significant impacts on their operations. By providing updates at four intervals each day, the NWS helps mariners make informed decisions and enhances their ability to manage risks associated with adverse weather.
