The January 13–16, 2024 North American winter storm brought wide-ranging and significant impacts across much of the continental United States, particularly in the Southern regions of the country.

Originating as an extratropical cyclone over the northeastern Pacific Ocean on January 12, the system, unofficially named Winter Storm Heather by The Weather Channel, moved ashore the following day, bringing heavy snowfall and ice accumulations to areas closer to the coastline than usual.

The winter storm then weakened over the Rocky Mountains, and leftover energy combined with an arctic front settling in near the Gulf Coast resulted in wintry precipitation in states that rarely receive it such as Texas, Louisiana, and Florida.

In the Northwest, ice accumulations and high wind gusts knocked out power to many as the system moved ashore, in addition to later triggering avalanches in the mountainous regions of the states of Colorado and Utah the following day.

The winter storm entered the Pacific Northwest on January 12, bringing heavy snow, ice, and high winds to Northern Oregon.

Freezing rain caused significant ice accumulations with some areas experiencing up to 1 inch (25 mm).
