A shortwave north of Hawaii this weekend will bring a front close
to Hawaii, but staying to the north before it weakens. A second
front may come close to the northern islands around Tuesday, with
a third and much stronger front approaching and stalling west of
the islands by the middle of the week. This is in association with
a deep trough and possible cutoff low West of Hawaii. There is a
lot of uncertainty in the evolution of this, but signal in the
guidance for heavy rainfall along this front, possibly impacting
Kauai, but unlikely for any substantial impacts east of the Kauai
outside of some increased precipitation chances. Wind speeds
across the entire island chain, but especially the western
islands, look moderate to gusty later in the week and next
weekend.
