...Remnants of Linda to bring heavy rainfall and strong winds
through Monday night...

The latest forecast continues to show the low pressure center
associated with former Tropical Cyclone Linda tracking through the
central islands on Monday.  Abundant deep moisture will accompany
the feature, with thunderstorms possible given persistence of
convection on the north side of the low in satellite imagery thus
far.  The threat for heavy rainfall over the state has a Flash
Flood Watch remaining in effect through very early Tuesday. 
Strong winds will also be likely with this system.  The expected
low track would give the northwestern islands the highest
potential for heaviest rain and strongest winds.

The state will see a return to typical trade flow from Tuesday
onward as Linda's remnants depart to the west.  Winds should
decrease gradually during mid-late week as mid-latitude high
pressure retreats northeastward, followed by some oscillation in
strength during Saturday-Monday.  Although an upper low will track
a ways to the northeast of the state and settle to the north,
generally windward-focused showers should be on the lighter side
with precipitable water values tending to be near and at times
more than one standard deviation below normal.
