...Major Hurricane Lester approaching the Hawaiian islands...

Satellite imagery shows a tightly compact Hurricane Lester just
upstream of the Hawaiian Islands. The Central Pacific Hurricane
Center has hurricane watches in effect the islands consistent with
a forecast track this weekend just to the north of state. Despite
the bulk of the 2 inch plus precipitatble water values mainly
concentrating around Lester, on Sunday and Monday the tail plume
of higher moisture swings east to west across the state to support
an increased rainfall threat. Stay tuned to the CPHC and WFO
Honolulu for updated info on Hurricane Lester.

The pattern returns to more typical flow regime in the wake of
Lester highlighted by a building upper/surface ridge NNE of the
islands and moderate mean trades. However, a possible upper-level
weakness arriving by midweek could could result in an increase in
windward showers into late next week.
