The Central Pacific Hurricane Center has Ela passing to the north
of the islands over the next few days, moving west away from the
islands later in the weekend. This track may act to temporarily
ease Hawaiian trade flow underneath to more seasonal levels. A
preferred model and ensemble composite indicates that a well
defined plume of enhanced moisture associated with the wave
containing Ela moves across the islands with the threat of locally
heavy showers this weekend. Blended precipitable water satelite
loops support this.

Early-mid next week, models and ensembles show high pressure
building north of the islands in the wake of Ela, producing a
transition to moderate to brisk island trades. While precipitable
water value dip after Ela's departure, lingering moisture may
still fuel some enhanced showers with heavy downpours over
windward areas, particularly over the Big Island. 

Please refer to the Central Pacific Hurricane Center (CPHC) for
the most recent information concerning Ela and also developing
Tropical Depressions 01C and 02c well south of the islands.
