"Northwest Braces for Weekend Storms and Flooding"

A weekend storm is expected to bring heavy rain, thunderstorms, and wind to major cities on both coasts, with flood alerts issued from Washington, D.C. to Maine. Snow melt in Maine could increase the risk of flooding. Travelers are advised to give themselves extra time and exercise caution on roads and railways. The Pacific Northwest is also bracing for another atmospheric river, with similar rainfall amounts expected. The Tennessee Valley and Michigan are experiencing heavy rain and low visibility, with the possibility of severe storms, including isolated tornadoes and large hail.
