As of the latest advisory issued by the Central Pacific Hurricane
Center, Hurricane Hector was located approximately 540 miles
west-southwest of Honolulu, and moving west at 16 mph. The plume
of deep moisture associated with the system should begin to shift
west of Hawaii by early Saturday. Until then, scattered showers
with locally heavy rainfall will remain a possibility. In the wake
of Hector, expect a resumption of moderate to fresh trades into
next week, with drier air also spreading across the state, as
surface high pressure covers much of the north-central and
northeastern Pacific. Models show good agreement on a
mid/upper-level weakness traversing the easterlies in the vicinity
of Hawaii by the early to middle part of next week, with an
associated increase in moisture. Thus, expect a slight increase in
shower activity by that time, largely but not exclusively focused
in favored windward locations.
