Long term [Saturday through Wednesday]

By the weekend through the new week, rainfall returns near to below average with no significant troughs or disturbances expected. Easterly flow will once again take over, but is forecast to be weaker than it is currently due to the high pressure to the southeast weakening and moving out of the area.

The easterly winds combined with a long period north swell will continue to bring rough seas across American Samoa's coastal waters through tonight. A High Surf Advisory was considered for north facing shores due to the swell's peak period time (~17 seconds). However, ultimately a High Surf Advisory was not issued as the swell is only a small portion of the total combined wave height, with the swell height only around 2 feet. Still, currents may be stronger than usual at times, especially along northeast facing shores that are impacted by both the easterly wind waves and the northerly swell.

Wave heights are forecast to briefly subside below advisory levels as winds weaken late week. However, by the weekend another swell, this time out of the south, is expected to again bring rough seas to the territorial waters. The swell this weekend will have an increased chance to bring advisory level surf conditions, having similar period times to the current northerly swell and being much larger (~6 feet).

PPG WATCHES/WARNINGS/ADVISORIES

Small Craft Advisory remains in effect.
