MIAMI (AP) — An unnamed storm and unusually high king tides are creating flooding issues along the Carolina coast as tropical storms swirl in the Atlantic and the Pacific.

Charleston, South Carolina, has seen about a dozen flooded streets, leading the city to offer free parking in public garages. An 8.5-foot high tide was predicted for Friday morning, marking one of the highest tides recorded in over a century.

The unnamed coastal storm and the high king tides present a risk of coastal flooding, particularly for areas like the Outer Banks in North Carolina. Dramatic weather conditions are anticipated from Friday through the weekend.

Meanwhile, in the Pacific, Tropical Storms Priscilla and Raymond are raising concerns over heavy rain and possible flash flooding across the U.S. Southwest, prompting flood watches for parts of Arizona, California, and Nevada.

Priscilla is currently located about 190 miles west-northwest of Cabo San Lazaro, Mexico, moving northward, while Raymond has a tropical storm warning in effect along the southwestern coast of Mexico.

As the hurricane season proceeds, additional storms like Jerry are forming, urging officials to remain vigilant as the La Nina pattern promises to affect weather conditions globally, with potential impacts ranging from heavy rainfall to droughts.
