Overview

• Multiple sprawling winter storms are causing disruptions across the U.S., with flights and school classes being canceled in advance in parts of the South and Midwest.
• Republican candidates campaigning ahead of Monday’s Iowa caucuses are contending with a blizzard warning covering most of the state.
• Advocates are particularly worried about homeless people as well as older residents who might be snowed or iced in, especially in the Pacific Northwest, where the winters are typically mild.
• In the Chicago area, advocates are also concerned for the growing population of migrants sent up from the U.S.-Mexico border, hundreds of whom are staying in parked “warming buses” to avoid sleeping outside.
• Heavy snow, high winds and white-out conditions are expected to envelop the Cascade Mountains, making travel “very difficult to impossible.”
