New storms are whipping up across the choppy Atlantic waves – which could bring even more suffering to millions of Americans still reeling from Hurricane Helene.

Meteorologists have warned that they are keeping a close eye on two weather systems “in the eastern tropical Atlantic,” one of which has “a high (80 percent) chance” of developing into a tropical cyclone within a week, according to the National Hurricane Center (NHC ). Another weather disturbance in the Western Caribbean has a “moderate (50%)” chance of developing into a tropical depression (a tropical cyclone with maximum winds of 38 mph) and the U.S. Gulf Coast “should monitor its progress,” warned the NHC.

The most worrisome weather system in the Atlantic Ocean is currently called Tropical Depression Twelve, although in the event of a hurricane it would be renamed Kirk. It remains unclear when, where or if it will actually land. (Hurricanes are named in alphabetical order, so following Hurricane Helene, Storms Isaac and Joyce are also currently being monitored at sea.)

The grim news of more storms comes after monster Hurricane Helene hit the US last week. More than 100 people have died and more than a million Americans are currently without power as buildings were destroyed, power lines collapsed and cars were swept away by storm surges and flooding.

The devastation began in Florida, but Helene traveled north, also hitting Georgia, South Carolina, North Carolina and Tennessee, as well as parts of Virginia, West Virginia, Illinois, Ohio and Kentucky.

The nervous residents of Florida are now watching with concern the weather developments, which could have further consequences in the near future. The Miami Herald warned of a particular system currently heading toward the Gulf of Mexico from the western Caribbean Sea.

The NHC reported on the social media site Sunday morning that interests in the northwest Caribbean and U.S. Gulf Coast should monitor progress.

A follow-up post on X revealed that there were two other potential warning signs further out to sea.

“Elsewhere, we are monitoring the development of two systems in the eastern tropical Atlantic,” the NHC said. “The system further west has a high (80%) chance and the system further east has a low (20%) chance of TC development.”

A tropical cyclone (TC) is an intense circular storm that can bring strong winds and develop into a full-blown hurricane, occurring when sustained wind speeds exceed 75 mph (120 km/h).

The agency is issuing warnings about the emerging developments, but there are currently no warnings.

Newsweek reached out to the NHC via email seeking additional information and comment on the tropical depression that could develop into Hurricane Kirk.

Meanwhile, cleanup efforts continue as friends and families mourn their deaths in the wake of Hurricane Helene, a powerful Category 4 storm.

According to the SAFFIR-SIMPSON hurricane scale, there are five categories that describe the strength of a given hurricane. The spectrum ranges from Category 1 (wind speeds of 120 to 155 km/h) to Category 5 (wind speeds over 250 km/h). Category 4 hurricanes have wind speeds between 131 and 155 miles per hour.
