.Short term...
[TONIGHT THROUGH TUESDAY NIGHT]...A cold front extending from a
low pressure system to the south will continue to produce
widespread showers and isolated thunderstorms for the territory
through Tuesday night. This system dropped nearly 4 inches of rain
since midnight, prompting a flash flood watch and flash flood
warning earlier today. As flooding conditions are expected to
persist through Tuesday night, the flash flood watch will remain
in effect until then.

Additionally, the trough will hold northerly winds around 10 to
20 mph through Tuesday night; Gusty winds are possible near
thunderstorms and showers.

.Long term...
[WEDNESDAY THROUGH MONDAY]...The aforementioned low pressure will
move further east by midweek, drawing all the showers towards it
and away from the territory. Scattered showers and light and
variable winds will begin Wednesday night and remain through
Saturday, before easterly trades return Sunday.

Latest wave heights observed at the PacIOOS buoys are around 7 to
9 feet due to a southeast swell. Wave heights are expected to
remain elevated through midweek. Additionally, another swell from
the south will keep the territory in advisory levels for the rest
of this duration. By Wednesday night, expect seas to be at its
lowest until Thursday night, before a second swell set from the
south builds in the area on Friday. Seas will likely reach
advisory levels by this time, and possibly a high surf warning
(15 feet or higher) over the weekend.
