What is a Heavy Freezing Spray Advisory?
A Heavy Freezing Spray Advisory is issued when conditions are favorable for significant ice accumulation on vessels due to freezing spray. This phenomenon occurs when water droplets from waves or sea spray freeze upon contact with surfaces that are at or below freezing temperatures. The accumulation of ice can severely impact the stability and maneuverability of vessels, posing a serious risk to maritime operations.
How to Prepare for a Heavy Freezing Spray Advisory
Mariners and those operating in affected areas should take several precautions to ensure safety during a Heavy Freezing Spray Advisory. Firstly, check and secure all safety equipment on board, ensuring it is readily accessible. Reduce speed to minimize sea spray and avoid unnecessary travel during the advisory period. Regularly monitor local weather updates and advisories to stay informed about changing conditions. Additionally, ensure that heating systems are operational to prevent onboard freezing and maintain a clear view by keeping windows and instruments free from ice accumulation.
When is a Heavy Freezing Spray Advisory Issued?
This advisory is typically issued by national weather services when meteorological conditions suggest that freezing spray will lead to a rapid and dangerous build-up of ice on vessels. Factors influencing the issuance include air and water temperatures, wind speed, and wave height. Mariners should remain vigilant and heed any advisories issued, adjusting their plans accordingly to ensure safety.
