Synopsis for Massachusetts and Rhode Island coastal waters:
A low pres tracks S of the waters this afternoon and tonight,
followed by a ridge of high pres for Thu. Another low press will
move across the waters Fri into Fri night. Otherwise, the main focus
will be on the potential for a rapidly intensifying low pres passing
near or SE of the 40N/70W benchmark later Sun into Mon. If this
system tracks close enough to the benchmark, very strong winds and
high seas would occur.
Coastal waters east of Ipswich Bay and the Stellwagen Bank National Marine Sanctuary:
