Weakened Helene continues to bring rain to the Southeast; The National Hurricane Center is monitoring two other storms in the Atlantic and a new system forming in the Caribbean.

As the recovery process begins in the Southeast Hurricane HeleneAt least 43 dead remain Caused billions of dollars in damageThe National Hurricane Center is monitoring a hurricane and tropical storm in the Atlantic and a possible new tropical storm forming in Helene’s wake.

HelenThe storm, which strengthened into a post-tropical hurricane on Friday, is expected to bring some rain and wind as it moves along the Kentucky-Tennessee border on Saturday, then crosses southern Pennsylvania and Virginia and heads towards the Atlantic Ocean on Tuesday.

National Hurricane Center is also tracking other storm activity in the Atlantic Ocean, including Tropical Storm Joyce, which formed in the central tropical Atlantic Ocean on Friday. The storm was located approximately 1,120 miles east of the Northern Leeward Islands with maximum sustained winds around 50 mph.

Tropical Storm JoyceTropical storm-force winds, currently extending up to 105 miles from its center, are moving northwest at 10 mph and are expected to weaken as they turn northwest and north Sunday night and Monday, the center said. The storm is expected to taper off early Tuesday and pose no threat of landfall.

NHC also tracks Hurricane Isaac and a system in the Caribbean

Hurricane IsaacThe hurricane, located in the central Atlantic Ocean about 695 miles west-northwest of the Azores, remained a Category 2 hurricane Saturday morning. the center said. Isaac is moving east-northeast at 20 mph and is expected to turn northeast over the next few days. Its maximum sustained winds are around 105 mph, with hurricane-force gusts extending up to 45 mph from the center. However, on Monday the storm is expected to become a post-tropical cyclone.

Neither Isaac nor Tropical Storm Joyce pose a threat to the United States.

However, the NHC said another low pressure area could form over the western Caribbean Sea by the middle of next week. Environmental conditions are expected to be “favorable for additional development” and could develop into a tropical depression as it enters the Gulf of Mexico by the middle to late next week, the NHC said Saturday. The storm will likely be called Tropical Storm Kirk. The center said there is a 40% chance of development within the next seven days.

If a storm develops, it’s expected to be west of Helene’s path, said Dan DePodwin, AccuWeather’s senior director of forecast operations. he said in a prediction. “But at this early stage, it is too early to rule out any possibility regarding the future track of a potential tropical storm,” DePodwin said.

The center said another tropical depression could form in the eastern and central tropical Atlantic next week. The system currently west of the Cabo Verde Islands is expected to move west and northwest across the Atlantic. The center estimates the chance of formation in the next seven days to be 60%.
