Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A frontal boundary will linger across the area
through today which will bring showers and thunderstorms across
the area. Otherwise, quiescent conditions will prevail through
Wednesday. Meanwhile, an area of low pressure is forecast to
form by midweek a couple of hundred miles north of the
southeastern or central Bahamas as a tropical wave interacts
with an upper-level trough. Some gradual development of this
system is possible thereafter, and a tropical depression could
form later this week while the system moves north-northwestward
or northward across the western Atlantic. This system has a low
chance of formation in the next 48 hours and a medium chance
through the next 5 days.
