An active tropical wave moving across the central tropical Atlantic has a significant chance of developing into a tropical cyclone in the coming days, according to the United States' National Hurricane Center (NHC). The system, designated as AL90, is currently located about 160 kilometers east-northeast of the Leeward Islands and is showing increasing signs of organization.
The atmospheric and oceanic conditions in the region are conducive to its development, potentially leading to the formation of a tropical depression or storm by the weekend as it moves northwestward and then north, between the Leeward Islands and Bermuda. The NHC has reported an 80% chance of formation within the next 48 hours and a 90% likelihood over the next seven days, making this system the most closely monitored in the Atlantic basin at present.
While the system does not pose an immediate threat to the southern Caribbean, experts caution that its path could change in the coming days. It is advised to stay informed with official updates. Additionally, the NHC is tracking another tropical wave, identified as AL99, situated halfway between Africa and the Lesser Antilles. Although it has lost some organization, it could potentially regain strength under more favorable conditions early next week. This system has a moderate development chance: 40% in 48 hours and 50% in seven days.
Moreover, a small area of low pressure southwest of the Azores has weakened and no longer presents development potential. This week, the powerful Hurricane Erin did not make landfall in the United States but did cause hazardous swells and rip currents along the entire East Coast, from Miami to Massachusetts. Authorities have urged beachgoers to adhere strictly to safety guidelines to avoid risks.

What is the current status of the tropical wave identified as AL90?
The tropical wave AL90 is displaying increased organization and is located approximately 160 kilometers east-northeast of the Leeward Islands. It has a high chance of developing into a tropical cyclone.
Is there any immediate threat to the southern Caribbean from AL90?
Currently, AL90 does not pose an immediate threat to the southern Caribbean, though its trajectory could change, and monitoring official updates is recommended.
What other tropical systems is the NHC monitoring?
The NHC is also monitoring another wave, AL99, which is currently less organized but may regain strength under favorable conditions. A low-pressure area southwest of the Azores has weakened and is unlikely to develop further.
