...SMALL CRAFT ADVISORY NOW IN EFFECT UNTIL 5 AM CHST TUESDAY...

* WHAT...East winds 15 to 20 kt with frequent gusts to 30 kt.

* WHERE...Marianas Coastal Waters.

* WHEN...Until 5 AM ChST Tuesday.

* IMPACTS...Conditions will be hazardous to small craft.

* ADDITIONAL DETAILS...The Small Craft Advisory was extended based on
  surface observations continuing to show frequent gusts in the 25 to
  30 knot range, as well as latest scatterometry data indicating an
  area of fresh to strong trade winds just east of Marianas coastal
  waters, which will continue to generate choppy sea conditions
  hazardous to small craft. Model guidance points to a gradual
  decrease in wind speeds late overnight through Tuesday, which 
  should allow seas to relax below hazardous levels.
 
PRECAUTIONARY/PREPAREDNESS ACTIONS...

Inexperienced mariners, especially those operating smaller
vessels, should avoid boating in hazardous conditions.
