Authorities in Texas responded to hundreds of accident-related calls Tuesday as an ice storm wreaks havoc on the roads and threatens parts of the South and central US with ice and sleet for at least another day.

The icy weather disrupted daily life for thousands across parts of Texas, Arkansas, Oklahoma and Tennessee, with freezing rain making roads slick, sending cars sliding and prompting officials to urge residents to stay home. School districts shut down classes in parts of Mississippi and Tennessee, and at least one healthcare system in Texas closed down its clinics amid the dangerous conditions.
