Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...An area of low pressure centered near 26N56W is
producing scattered showers and thunderstorms. Although
environmental conditions are not very favorable for development,
a short-lived tropical depression can not be ruled out if
convection becomes better organized while the system moves N at
around 5 kt over the central subtropical Atlantic. There is a
low chance of tropical formation over the next 48 hours.
Otherwise, a weak cold front will move off the SE coast of the US
this afternoon, then slowly move across the waters N of 25N
through Mon night.
