While Hurricane Erin’s presence continues to be felt along the east coast of the U.S., the National Hurricane Center has two other developments on its radar.
First spot
A tropical wave located several hundred miles east of the Leeward Islands continues to produce a broad area of disorganized showers and thunderstorms. Environmental conditions appear conducive for gradual development of this system, and a tropical depression could form by this weekend while it moves near or to the north of the northern Leeward Islands.
There’s a 10-60% chance of formation over the next 2-7 days.
Second spot: Invest AL99
Satellite-derived surface wind data from earlier today revealed that a concentrated area of showers and thunderstorms located several hundred miles southwest of the Cabo Verde Islands lacks a closed surface circulation.
Environmental conditions appear marginally favorable for additional development over the next day or so while the system moves west-southwestward at around 15 mph and a short-lived tropical depression could form.
By the end of the week, environmental conditions are expected to become unfavorable for further development.
There’s a 40% chance of development over the next 2-7 days.
The next named storms are Fernand and Gabrielle, respectively.
