...HIGH SURF ADVISORY IS CANCELLED...
...HIGH RIP CURRENT RISK IS CANCELLED...

Buoy data at both Ritidian and Tanapag show that the northerly swell
has diminished to below 6 feet with the average swell period near 11
seconds. This brings high surf conditions below advisory criteria for
north facing reefs, as well as rip current risk down to moderate.
With this data, the High Surf Advisory and High Rip Current Risk were 
canceled.

Surf may approach hazardous levels Sunday night due to a pulse of
long-period swell that will move into the region. Seas may only rise
a foot or so, but the period may potentially increase to 14 seconds.
This would be enough to reach High Surf Advisory levels for north 
facing reefs.
