A significant winter storm is set to impact much of the US this weekend, bringing dangerous freezing rain that could lead to widespread power outages and hazardous travel conditions. As temperatures are expected to remain below freezing for over 24 hours, authorities warn that ice accumulation may disrupt power supply, with millions at risk of losing heat. Preparations are underway as electric companies urge residents to be ready for the potential impacts of this ice storm, which poses greater danger than snow due to its effects on roadways and power lines. Travelers are advised to stay informed and take precautions to ensure safety during this severe weather event.
