An developing area of low pressure over the SW Gulf will meander
over the southern Gulf during the next several days, with high
potential to become a tropical depression in the day or two. A

fresh to strong east to northeast winds.

21.8N 55.6W by Fri morning. Swell generated from Teddy will 
impact the Greater Antilles and the Bahamas this weekend as it 
continues on a northwest track. This large northeast swell will
