Tropical Weather Outlook for the next 7 days:

— Atlantic waters a few hundred miles off the North Carolina coast: A storm-force non-tropical low has a 40% chance of tropical or subtropical formation within the next seven days. It should move north-northeast and accelerate away from the United States late this week, but winds, coastal flooding and dangerous surf are expected along portions of the East Coast during the next few days.

— The eastern Pacific, 150 miles west-southwest of Cabo Corrientes, Mexico: Post-Tropical Cyclone Trudy has sustained winds near 35 mph and is moving north at 2 mph. The remnant low should turn slowly west-northwest and dissipate within 48 hours.
