.Short term...
TONIGHT THROUGH FRIDAY NIGHT...A ridge to the southeast is slowly
retreating eastward. A trough to the south will remain nearly
stationary through the next few days. A high pressure to the
farther south is slowly migrating east. Showers will remain to the
south of the islands and variable winds will continue throughout
the short term. RAOB from this afternoon depicts a conditional
unstable profile. Therefore, will hold showers at scattered
tonight before diminishing to isolated on Thursday morning.

.Long term...
SATURDAY THROUGH WEDNESDAY...Models continue to hold showers to
the south and variable winds over the islands through the new
week. As the high pressure continues to drift east, the trough to
the south will also hold winds to light and variable across the
islands through the new week.


Rough seas of 7 to 9 ft will persist tonight through Sunday
morning with south swells passing across the territory. However,
models continue to hold these rough conditions through the
beginning of the new week due to strong trades to the south of the
islands. These winds are responsible in maintaining advisory
levels through the start of the new week.


High Surf Advisory remains in effect
Small Craft Advisory remains in effect
