1037 AM EDT Sat May 17 2025

.SYNOPSIS FOR MID ATLC WATERS...A warm front over the far
northern waters will lift N of the area this afternoon. A cold
front will approach from the W today, and then move E and SE over
the waters tonight into Sun. Mariners should use caution for
locally gusty winds and rough seas in and near locally heavy
tstms over the waters through tonight. Otherwise, low pressure
will drift E and pass N and then NE of the area Sun night into
Tue as a series of secondary cold fronts or low pressure troughs
move E and SE over the N and central areas. A weak high pressure
ridge will build S and SE over the region later Tue and Tue
night as a warm front extends E off the SE coast. The warm front
will lift N across the area Wed and Wed night. A developing low
pressure area will approach from the W and SW, and then move just
off of the Delmarva or New Jersey coast Wed night, with a
trailing cold front extending S along the coast.
