Most elements of the forecast have maintained continuity over the
past day.  During the first part of the week the northwestern
islands should remain in the greatest deep moisture as represented
by precipitable water values of near to slightly greater than two
inches versus 1.75 inches or slightly less toward the Big Island. 
Relatively light winds should allow for land/sea breeze influence
on any shower activity that occurs.

Consult Central Pacific Hurricane Center products for latest
information regarding Tropical Storm Jimena.  Currently Jimena is
forecast to track to the north of the islands by Wed-Thu as it
slowly weakens but there remains some spread in the guidance as to
exactly how close to the islands Jimena tracks.  The idea of
increased moisture and thus potential for areas of heavier
rainfall appears somewhat less sensitive to the exact track of
Jimena.

With the departure of Jimena, the Fri-Sun period should see a
trend to moderate/brisk southeasterly winds in association with
flow around eastern Pacific high pressure and a sharpening frontal
boundary developing over the central Pacific.  In this time frame
rainfall should become more terrain focused.
