Hazardous marine conditions are expected across western Lake Superior today and tonight. Strong and gusty west to northwest winds will cause waves to build throughout the day, prompting Small Craft Advisories. Peak wind gusts between 25 and 30 knots and wave heights up to 2 to 4 feet are expected during peak hours today before conditions gradually diminish tonight. Inexperienced mariners, especially those operating smaller vessels, should exercise caution or avoid navigating in these conditions. Check local marine forecasts before heading out onto the water.
