Satellite imagery indicates thunderstorms to the south and north
of the territory, as a trough lingers across the region. Behind
the trough, a high pressure system is building, and as it
strengthens, it will push the showers from the south over the
Islands Christmas afternoon. These showers are forecast to
combine with showers to the north increasing the risk for flash
flooding. Unsettled weather will continue until the new week as
the trough remains in the area. Winds are anticipated to become
more gusty Thursday due to thunderstorms, but most of the forecast
period, expect a light breeze.

Conditions are expected to gradually improve by next Tuesday, as
the trough begins to move northward. Expect variable winds and
scattered showers by Tuesday night.

Calm seas persist as no significant swells or winds are observed
at the PacIOOS buoys. Expect ocean conditions to continue through
the forecast period. However, possible thunderstorms nearby could
elevate seas at times.
