From left to right…

* Green:

Lee lost its tropical-cyclone-status at 5am Saturday morning, while its remnants brought minor effects to northeastern USA + southeastern Canada.

…the final advisory on Lee was issued at 11am today.

* Purple:

Margot also lost its tropical-cyclone-status at 11am this morning.

…The remnants of Margot will continue making a slow clock-wise circle in the central north Atlantic and possibly bring minor effects to the (Portuguese) Azores Islands.

* White:

Tropical Storm Nigel (formerly Tropical Depression#15) formed at 11pm last night in the central Atlantic -- about midway between Africa & the Caribbean.

...it will likely further strengthen into a hurricane by Mon -- while passing well NorthEast of the Caribbean.

...Nigel poses no direct threat to the Caribbean, but can kick up rip currents/ground swells during the next few days -- use Sea Caution!

* Grey:

A non-developing tropical wave -- centered along 36°W -- currently has no chance of developing.

…it currently poses no threat to the Caribbean, but may bring a couple showers to the SSS & surrounding Islands by this weekend.

We will continue to monitor its progress.

* Red:

The developing tropical wave, which is expected to emerge off the coast of Africa by Tue/Wed -- already has a low (0%) to medium (40%) chance of developing within the next 2-7 days.

…it is way too early to determine the outcome of this system.

We will definitely continue to monitor its progress.
