* waves/seas...combined seas increasing thursday to 7 to 11
  feet...then increasing further on friday through saturday...
  possibly as high as 12 to 19 feet.

precautionary/preparedness actions...

a small craft advisory means that wind speeds of 21 to 33 knots
and combined seas of 10 feet or greater are expected to produce
hazardous wave conditions to small craft. inexperienced
mariners...especially those operating smaller vessels should
avoid navigating in these conditions.

a gale watch is issued when the risk of gale force winds of 34 to
47 knots has significantly increased...but the specific timing
and/or location is still uncertain. it is intended to provide
additional lead time for mariners who may wish to consider
altering their plans.
