What to Wear & Road Tips
Go with layers: a warm base, insulating mid-layer, and a wind-resistant jacket. Add a toque and insulated gloves—today’s and tonight’s northwest gusts bite. Waterproof, grippy footwear will help on wet leaves and any icy spots after dark. Drivers: expect crosswinds on open stretches and black ice tonight and early Sunday.
