Struggling Tropical Activity in the Atlantic

Tropical Depression 7 appeared destined to strengthen into Tropical Storm Gordon before the start of the weekend. However, the depression became the victim of strong wind shear and weakened to a tropical wave on Saturday.
The Hurricane Center warns that the wave will continue to deliver a few drenching and gusty bands of rain to the Leeward Islands today. Additional rain squalls will graze the Virgin Islands, Puerto Rico, Hispaniola and Jamaica through midweek as the wave races westward through the Caribbean. During that time, the window will not open for the wave to organize back into a tropical depression.
In the far eastern Atlantic, a tropical low that was once a robust feature as it moved off the coast of Africa has succumbed to dry Saharan dust and cool ocean waters northwest of the Cape Verde Islands.
The low will escape the Saharan dust and reach warmer water toward midweek, which could lead to tropical development. However, the low may then encounter another hurdle in its quest to strengthen--an area of stronger wind shear in the central Atlantic.
