The state will see trade winds supported by strong high pressure
covering much of the eastern half of the Pacific with an
interruption from the remnant circulation of Tropical Storm Celia
early next week and then what remains of Hurricane Darby toward
the end of next week.

Expect moderate trades to continue into the first part of the
weekend while precipitable water values decline briefly.  Then
trades will be interrupted for at least a portion of the
Sunday-Tuesday period as the remnant of T.S. Celia tracks to the
north of the islands.  One or more bands of enhanced moisture
extending to the south of the feature will likely cross the state
and bring the potential for heavier rainfall.  Trades should
resume by Wednesday-Thursday along with a lighter trend for
showers.  Current guidance shows better than average clustering
toward the surface reflection of Hurricane Darby reaching just
west of 150W longitude near 17-19N latitude by day 7 Friday.  At
this pace moisture/rainfall should begin increasing near the Big
Island next Fri.
