What to Wear & Road Tips
Layer like you mean it: thermal base, insulating mid-layer, and a wind-resistant parka. Add a toque, insulated mitts, neck warmer, and winter boots with aggressive tread. Drivers: expect whiteouts in bursts, drifts on exposed sections of Hwy 17, and black ice tonight. Slow down, keep lights on, and carry a winter kit (scraper, brush, shovel, traction aid, blanket).
Lake Superior Trivia
When an Arctic front sweeps over warmer lake water, the atmosphere “loads up” and fires narrow snow bands. One side of town gets hammered while the other side sees sun—classic squall fingerprint.
