A very normal weather pattern sets up across the Hawaiian Islands
this week. Hurricane Lowell, currently impacting Ni'ihau and 
Kauai, will be rapidly moving away from the main Hawaiian Islands
by the start of this period 00Z Wednesday. A feeder band or two 
may still be impacting any of the islands at the start of the
period, but as Lowell continues moving away, the bands will
rapidly dissipate. For more information on Hurricane Lowell,
please see www.hurricanes.gov.

The rest of the week will feature typical northeast trade winds 
resetting up across all of the islands in the wake of Lowell, 
with no significant weather features expected through Monday. By
Tuesday, some of the long-range guidance suggests a weak tropical
wave may approach the Big Island before it too dissipates. Should
the tropical wave make it on Tuesday, expect more consistent
rainfall on the east-facing sides of the Big Island Tuesday
afternoon. Otherwise no unusual weather is expected.
