moderate to isolated strong rainshowers from 02N to 08N between
20W and 30W.

An Atlantic Ocean surface trough is along 42W/43W from 12N
southward moving westward 10 to 15 knots. Isolated moderate from
10N southward between 40W and 50W.

An Atlantic Ocean tropical wave is along 53W from 12N southward,

eastward. Rainshowers are possible also in the Atlantic Ocean from
Cuba northward from 70W westward. A surface trough is along
