.DISCUSSION...
Persistent south-southeast flow of 10 to 15 knots will remain in
place through the middle of this week. Seas will remain well below
any hazardous limits at 1 to 3 feet through the period. The greatest
concern will be any shower or thunderstorm impacts associated with
disturbances that move towards the coastal waters through the week.
These disturbances will cause locally higher winds and seas around
the storms they produce. Afterwards, winds may become light and
variable for 3-6 hours before the synoptic south-southeast winds
take over again.
