As per the National Hurricane center track forecast, the remnants
of Tropical Storm Celia will be passing between 300 and 400 miles
north of the islands on Sunday and Monday contributing to an
increased likelihood of showers as precipitable water values
increase over the period.  A retrograding upper weather pattern
over the central to north central Pacific will allow heights to
build across the eastern to northeastern Pacific with the
development of a large 594+ dm upper high north of Hawaii. The
surface high associated with this anticyclone begins as a 1032 mb
center near 45N 135W that drifts westward to near 45N 150W and
builds to near 1040 mb by Sunday as the remnants of tropical storm
Celia should pass north of the islands. However, the circulation
about Celia should disrupt the trade wind pattern until it passes
on Tuesday and Wednesday and high pressure builds to the north and
an increase in the trade wind flow appears more likely.
