Lighter than usual trade winds will develop as a weak, low level
trough drifts west of the state. A few showers will generate in
the lee of the mountains and over locations where sea breeze lift
occurs. By the end of the week, and through the weekend, the trade
winds will increase as mid-level ridge build north of the islands.
With sporadic enhancements of moisture passing through, isolated
to scattered windward showers are likely in a fairly typical trade
wind pattern. 

Hurricane Barbara, located hundreds of miles east of the Islands,
is forecast to track northwest through Friday evening then more
westward over the weekend. The current projection has it weakening
to a Tropical Depression near 18N, 148W by Sunday night. The
guidance continues to show typical spread for this evolution as it
either approaches the islands or gets suppressed to the south.
This system will have to be watched going forward for its
potential impacts on the islands.
