Forecasters are monitoring developments from tropical waves that may reach the southeastern Caribbean Sea in the next 36 hours or so. Immediately after that, there is the second tropical wave in the Atlantic Ocean.

According to experts, the waves closest to the Caribbean are expected to continue on a nearly westward route, probably until next week, as is typical of tropical waves.

According to the National Hurricane Center, a cyclone valley formed off Africa late last week and continues to produce chaotic showers and thunderstorms. Development can be slowed later this week and this weekend as it travels west-northwest at 15-20 mph.

“Because it crosses the Atlantic Ocean, it has the potential to develop gradually and gain enough tissue to become a tropical cyclone,” said Adam Douty, senior meteorologist at AccuWeather.

As of 8 am on Tuesday, it was located about 850 miles east of the islands of the Lesser Antilles, which form the eastern border of where the Caribbean meets the Atlantic Ocean. According to the National Hurricane Center, it is expected to arrive on the island by Wednesday night.

According to forecasters, it will occur with a 30% chance in the next 48 hours and a 40% chance in the next 5 days.

Behind it is the second tropical wave in the Atlantic Ocean, about 800 miles from West Africa. It can also slow down development as it travels west-northwest at 20 mph this week. As of Tuesday morning, the probability of development was low, only 20% over the next five days.

Meanwhile, the fourth short-lived storm of the season, Tropical Storm Danny, formed Monday afternoon and landed just before 8 pm north of Hilton Head, South Carolina.

By Tuesday morning it was the remaining lows. However, flash floods continue to cause heavy rainfall, leaving the threat of flash floods in western and northern Georgia and northern Alabama, forecasters said.

The US National Oceanic and Atmospheric Administration predicted a busy hurricane season this year, estimating 13 to 20 named storms.

Danny was the second named storm of the 2021 season that affected the United States. A tropical cyclone claudet formed over the Gulf of Mexico on June 19 struck the Gulf Coast of the United States, killing 13 people in Alabama.

Prior to Danny and Claudette, a tropical cyclone building occurred in early June and a tropical cyclone anouncer occurred in May, neither of which affected the continental United States.
