"Extreme Weather Alert: Record-breaking cold, floods, and winter storm updates"

A massive winter storm is set to bring record-breaking cold temperatures and severe weather across the US, with wind chills as low as -45F (-42C) forecast in Iowa and wind gusts up to 50mph (80km/h) from Texas to New York. The National Weather Service has issued alerts for blizzards, large hail, thunderstorms, and tornadoes in nearly every state, prompting concerns about energy supply in Texas. Republican presidential candidate Nikki Haley cancelled in-person events in Iowa due to the potentially dangerous weather conditions, while her rivals Ron DeSantis and Vivek Ramaswamy are still scheduled to press on ahead of Monday's caucus.
