Isaac strengthens into a hurricane in the Atlantic Ocean and Tropical Storm Joyce forms

MIAMI (AP) — Forecasters say Isaac has strengthened into a hurricane in the open waters of the Atlantic Ocean and could cause dangerous waves in parts of Bermuda. And Tropical Storm Joyce formed Friday in the Atlantic, though it wasn’t threatening land. There were no coastal watches or warnings in effect for either storm. Isaac was about 980 miles east-northeast of Bermuda, with maximum sustained winds of 75 mph. The U.S. National Hurricane Center says waves from Isaac could cause life-threatening surf and rip current conditions in Bermuda and potentially dangerous waves could spread to the Azores.
