Atlantic May Spawn Two New Tropical Systems Into Next Week

While Tropical Depression Nine is likely to diminish, two other systems have the potential to develop in the tropical Atlantic into next week.
The next names on the list of tropical storms in the Atlantic are Ida and Joaquin. There is a very good chance that at least one new tropical storm will be named into next week.
Tropical Depression Nine as of 5 p.m. EDT Thursday was about 1100 miles east of the Lesser Antilles.
The system has most likely missed its chance to become a tropical storm.
According to AccuWeather Hurricane Expert Dan Kottlowski, Tropical Depression Nine will probably never become much stronger since it is now entering a hostile environment.
"Increasing wind shear will likely lead to the system's demise before the week comes to a close," Kottlowski said.

Current sustained winds with the system are 30 mph. A system that has developed circular motion with showers and thunderstorms must have sustained winds of 39 mph or greater to be dubbed a tropical storm.
Steering winds will cause the system to drift to the north into over the central Atlantic. As a result, the system is not a threat to the United States or the Caribbean.
A second system, designated 95L, is located southwest of the Cape Verde Islands and could soon become a tropical depression or storm.

"Environmental conditions should remain favorable for further development of 95L through the end of the week with the system likely to become Tropical Depression Ten," Kottlowski said.

According to AccuWeather Meteorologist Becky Elliott, "This system will track farther west than Tropical Depression Nine."
How soon 95L makes a northwest turn will determine impact, if any, on the Lesser Antilles next week. There is a chance this system will also curve northward and wind up over the middle of the Atlantic instead.

The area of disturbed weather near Florida contains some of the leftover moisture from Grace.
Environmental conditions around Florida are not favorable for development in the short term.
"The system will enhance rainfall over Florida through Thursday," Kottlowski said.

The torrential downpours can lead to flash flooding, while some of the stronger thunderstorms could produce brief strong wind gusts and a few waterspouts.
This feature could slowly organize as it drifts off the East coast of the U.S. later this weekend into next week, provided it can overcome strong winds aloft or the winds aloft decrease.
The area off the East coast of the U.S. will remain a spot for potential tropical development through next week.
"So far, nine tropical systems have developed in the 2015 Atlantic Hurricane Season," Elliott said. "The most recent system [to acquire a name] was Henri, which brought rain and wind to western Europe as a tropical rainstorm this week.
Throughout the tropical Atlantic and over much of the western part of the basin, waters are warm enough to support development.
