The deadly Arctic outbreak associated with two major winter storms has maintained its grip on much of the Lower 48 states. In Mississippi, more than 110,000 households are still without electricity, while another nearly 90,000 are powerless in Louisiana, according to the latest figures from the website poweroutage.us.

President Biden has approved emergency declarations for Texas, Louisiana and Oklahoma, sending federal equipment, supplies and other resources to the affected states. Since Sunday — when temperatures plunged sharply — there have been at least 47 deaths linked to the storm, according to tracking by The Washington Post.
