The NHC has issued its final advisory on Erin. We are tracking two other systems in the Atlantic, one likely to become a tropical storm this weekend. No development is forecast in the Caribbean Sea or Gulf through the next 7-days.
ATLANTIC DISTURBANCES
1. Southwestern Atlantic (in red above, AL90):
Showers and thunderstorms continue to show some signs of organization in association with a trough of low pressure located about 250 miles northeast of the northern Leeward Islands. Environmental conditions appear conducive for further development of this system, and a tropical storm is very likely to form this weekend while it moves northwestward and then northward over the southwestern Atlantic. The next name is "Fernand".
2. Eastern Tropical Atlantic (in yellow, AL99):
Showers and thunderstorms associated with a tropical wave located about midway between Africa and the Windward Islands remain disorganized. While there is still some chance that a short-lived tropical depression could form during the next day or so, the system is expected to move through a less conducive environment on Saturday. The wave could reach a slightly more favorable environment late this weekend into early next week as it approaches the Windward Islands.
Erin
Erin is post-tropical and the final advisory has been issued. The cyclone is racing toward the east-northeast at 33 mph. This general motion with an increase in forward speed is expected, followed by a turn back to the northeast on Sunday.
On the forecast track, the center of Erin will pass south of Atlantic Canada today and tonight, and then race across the north Atlantic waters.
Maximum sustained winds are near 90 mph with higher gusts. Erin will remain a powerful hurricane-force low pressure system through the weekend.
Erin is growing in size. Hurricane-force winds extend outward up to 140 miles from the center and tropical-storm-force winds extend outward up to 435 miles.
