## extract

Small Craft Advisory — Guam Coastal Waters; Rota Coastal Waters; Tinian Coastal Waters; Saipan Coastal Waters
Severity: Minor. Certainty: Likely.
* WHAT...West winds 15 to 25 kt with gusts to 35 kt and seas 8 to
11 feet expected.

* WHERE...Marianas Coastal Waters.

* WHEN...Until 6 AM ChST Friday.

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

* ADDITIONAL DETAILS...Fresh to strong westerlies with near-gale
to gale force gusts will prevail across the Marianas through
early Wednesday, especially near heavier showers as a westerly
monsoon surge continues. Additionally, distant Typhoon Dolphin
(12W) is generating a long-period north to northeast swell that
is moving through the Marianas, which will continue shift north
over the next day or so, then northwest. Meanwhile, the
developing monsoon pattern will lead to increasing west to
southwest swell over the coming days. The combination of these
elevated swells and wind waves will keep seas at around 10 feet
across the coastal waters, maintaining hazardous sea conditions
for much of this week.
