The 03Z Central Pacific Hurricane Center advisory for Tropical
Storm Linda shows the system becoming post-tropical shortly, with
a remnant low likely to track near Kauai by next Monday.  Models
and ensemble means agree that an area of enhanced deep moisture
accompanying the remnant low will cross the state from east to
west during Sunday-Monday and depart by Tuesday, so expect some
increase of rainfall during the first part of the week.  There
should also be a period of lighter winds to the south of the
remnant low track.  Weather effects over northwestern areas will
be very sensitive to the exact track, with only a slight southward
change potentially leading to a significant increase of
winds/rainfall at some locations.  Consult the latest CPHC
products for further information on Linda.  By mid-late week the
state should return to a moderate-brisk trade pattern as supported
by mid-latitude high pressure while precipitable water values
settle to modestly below normal levels.  Thus primarily windward
and mountain rainfall should be in the lighter half of the
spectrum.  Also most rainfall should be fairly light in the trade
pattern existing late this week ahead of Linda's remnant low and
moisture.
