Boaters on Lake Superior are being warned of hazardous conditions Tuesday morning, as dense fog continues to blanket much of Michigan’s northern shoreline. With visibility dropping to less than one nautical mile in several areas, mariners should take extra precautions to ensure their safety.
Dense Fog and Limited Visibility
According to the National Weather Service in Marquette, Dense Fog Advisories remain in effect until 8 a.m. EDT for waters stretching from Ontonagon to Whitefish Point and Isle Royale National Park.
An extended advisory covering offshore zones from the Portage Canal to Grand Marais will last until 11 a.m. Visibility in these areas is expected to be severely limited, creating dangerous navigation conditions for boaters.
Small Craft Advisory in Effect
In addition to the dense fog, a Small Craft Advisory will take effect at 1 p.m. Tuesday for waters from Eagle River to Manitou Island. Gusts could reach up to 25 knots, with waves building as high as 4 feet. This combination of wind and waves will make conditions treacherous, especially for smaller boats and less-experienced mariners.
Safety Precautions for Mariners
Navigators are urged to take extra care when traveling under these conditions. Here are some essential tips to stay safe:
- Use Radar and Fog Signals: In low-visibility conditions, radar is critical for navigation. Make sure to sound proper fog signals when visibility is compromised.
- Ensure Navigation Lights Are On: Keeping your lights active is vital for being seen in the fog.
- Avoid Non-Essential Travel: If your trip is not urgent, it is recommended to delay travel until conditions improve.
Typical Summer Conditions on Lake Superior
This type of fog and wind combination is typical in early summer, as warmer air meets the cold waters of Lake Superior. Boaters are advised to stay informed and monitor weather updates, as additional advisories may be issued later in the week if the conditions persist.
