Study Notes
Weather Emergencies
- Weather can rapidly change, creating unpredictable situations for boat and PWC operators.
- Even meteorologists struggle to forecast sudden weather shifts.
Appropriate Action
- Always monitor weather conditions and forecasts while operating a vessel.
- It is the operator's duty to take necessary actions based on weather developments.
NOAA Weather Radio Frequencies
- NOAA broadcasts weather updates on VHF-FM radio from various frequencies: 162.400 to 162.550 MHz, updated hourly.
Observing Conditions
- Signs of dangerous weather include dark clouds, shifting winds, distant thunder, and changes in barometric pressure.
- A rising barometer indicates fair weather; a falling barometer means bad weather is approaching.
- Watch for lightning and rough waters, and stay alert, especially to the west where bad weather typically originates.
Preparing for Severe Weather
- Slow the vessel but maintain enough power for control.
- Secure all hatches and equipment to minimize risks.
- Activate navigation lights and sound a fog horn in low visibility conditions.
- Keep bilges clear and be ready to bail water if needed. Disconnect electrical equipment during lightning.
Passenger Safety
- Ensure all passengers wear USCG-approved personal flotation devices (PFDs) securely.
- Have passengers sit low in the vessel for stability during inclement weather.
Thunderstorm Proximity
- Count seconds between lightning and thunder; divide by five to estimate distance in miles from the storm.
Bailing
- Bailing refers to removing water from the vessel using a bucket.
Storm Navigation
- If safe, head to shore; if caught in a storm, it may be safer to stay in open water.
- Position the bow at a 45-degree angle to the waves; for PWCs, head directly into the waves.
- Use a "sea anchor" if the engine fails to maintain heading into the wind.
Small Craft Advisories
- A Small Craft Advisory is issued when wind speeds range from 21 to 33 knots (24 to 38 mph), indicating danger for smaller vessels.
Weather Warnings
- Gale Warning indicates winds between 34 to 47 knots (39 to 54 mph).
- Storm Warning applies to winds at 48 knots (55 mph) and above.
- Hurricane Warning is for winds of 64 knots (74 mph) and above.
Emergency Communication Tools
- Carry Visual Distress Signals, VHF Marine Radio, mobile phones, and EPIRBs for emergency assistance.
- VHF radios should be monitored continuously; they are crucial for distress calls.
VHF Radio Usage
- Channel 16 is primarily for distress; misuse can lead to penalties.
- Issuing a MAYDAY involves repeating the word three times and providing critical details about the emergency.
Common Channel Frequencies
- Commonly used channels include:
- Channel 6: Intership safety communications.
- Channel 9: Vessel communications and calls to Coast Guard.
- Channel 13: Navigational communications.
- Channel 22: Coast Guard announcements and weather warnings.
- Channels 68-71: Recreational vessel communications.
Summary
- Maintain vigilance to ensure safety during weather emergencies.
- Be prepared with adequate communication tools and follow proper procedures for emergency situations.
