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

.SYNOPSIS...A deep layered upper trough N to S across the
central Caribbean will lift northward into the Atlantic this
weekend. A broad area of low pressure over the southeastern
Caribbean Sea is producing a large area of disorganized showers
and thunderstorms extending across the eastern Caribbean from
the Windward Islands west- northwestward for several hundred
miles, mostly E of 70W. Environmental conditions are forecast to
be conducive for gradual development over the next few days, and
a tropical depression is likely to form this weekend or early
next week while the disturbance moves slowly westward or west-
northwestward over the central Caribbean Sea. Regardless of
development, locally heavy rainfall is possible over portions of
the Lesser Antilles, the Virgin Islands, and Puerto Rico through
this weekend. This system has a low chance of development in the
next 48 hours and a high chance in the next 5 days. Expect
scattered showers and thunderstorms to continue through the
weekend with the trough and potential developing low.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A surface trough over the southwestern Atlantic 
continues to produce scattered showers and thunderstorms mainly
between 63W-68W. A 1014 mb surface low pressure with has formed 
along the the northern portion of the trough near 31N67W.
Environmental conditions are forecast to be only marginally
conducive, and any development should be slow to occur. By late
Saturday, upper-level winds are forecast to become even less
favorable for development, and the low is expected to begin
interacting with an approaching frontal system. This system has
a low chance of development in the next 48 hours and 5 days. A
frontal system to the north of the area will interact with the
low and could bring moderate to rough seas in NE swell through
the weekend west of 70W.
