Synopsis for Caribbean Sea and Tropical N Atlantic from
07N to 19N between 55W and 64W

.SYNOPSIS...A complex, large non-tropical low pressure system is
expected to develop this weekend over the northeastern Caribbean
sea and southwestern Atlantic. The system is expected to 
initially be very broad and disorganized, but environmental 
conditions could support gradual subtropical or tropical 
development beginning early next week while it moves generally 
northward or northwestward. Regardless of development, strong 
winds along scattered to numerous showers and thunderstorms are 
expected across most of the NE Caribbean Fri night through Sat 
night. Strong winds are also expected Sat through Sun night in 
the southwestern Caribbean associated with low pressure forecast 
to develop in the eastern Pacific monsoon trough.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A cold front extending from near 31N58W to 27N65W to
to 28N72W and to 30N78W will merge with a reinforcing cold front
today and then weaken into a frontal trough on Fri. Strong high 
pressure north of the area and in the wake of the front will
lead to strong to near gale force easterly winds across the 
northern waters, mainly north of 27N today through Sat night. 
Large northeast swell following the front will push southward 
across the entire area over the weekend. Looking ahead, a large 
non-tropical low pressure system is expected to develop this 
weekend over the northeastern Caribbean sea and southwestern 
Atlantic. The system is expected to initially be very broad and 
disorganized, but environmental conditions could support gradual 
subtropical or tropical development beginning early next week 
while it moves generally northward or northwestward.
