Two more named storms as Hurricane Isaac and Tropical Storm Joyce forms in the Atlantic

Isaac intensified into a hurricane on Friday in the open waters of the Atlantic Ocean and may generate dangerous waves in the Azores, while Tropical Storm Joyce formed without posing a threat to land, according to forecasters.

Isaac was located about 1,080 miles (1,740 kilometers) west of the Azores, with maximum sustained winds of 75 mph (121 kph) and moving east-northeast at 18 mph (29 kph).

Currently, there are no coastal watches or warnings in effect for either storm. However, the US National Hurricane Center cautioned that Isaac's waves could create life-threatening surf and rip current conditions in the Azores. Earlier advisories mentioned potential impacts on Bermuda, but this was not included in the latest update. Isaac is expected to strengthen before gradually weakening by the end of the weekend.

As Hurricane Helene made landfall in northwestern Florida as a Category 4 storm, it left behind flooding, damage, and widespread power outages before weakening early Friday.

On the same day, Joyce strengthened into a tropical storm, located about 1,325 miles (2,130 km) east of the northern Leeward Islands. Joyce has maximum sustained winds of 40 mph (65 kph) and is moving northwest at approximately 13 mph (20 kph).

The storm is expected to gradually strengthen through Sunday before weakening early next week.
