Lake effect snow can create hazardous travel conditions, with sudden transitions from clear roads to heavy snow and poor visibility. Snow bands may shift unpredictably, making it difficult for plows to keep up. Prolonged exposure to cold can lead to hypothermia, especially in poorly heated homes. Strenuous activities like shoveling wet or deep snow can increase the risk of heart strain, potentially causing chest pain, dizziness, or nausea. Residents should monitor local forecasts and prepare for power outages and dangerous travel.
