The deep layer/warm core high pressure will remain north and west
of Hawai'i as a TUTT low slides across the islands.  This will
bring an increase of moisture--leading to higher chances of
showers for Hawai'i. By late Monday and into early Tuesday, high
pressure will build across the islands--bringing drier conditions.
 In terms of Hurricane Hector, The 06Z GFS/00Z ECMWF/00Z CMC/00Z
UKmet in addition to their respective means are all now showing
Hector will move south of the the islands on Wednesday/Thursday. 
However, the GFS and its mean, in addition to the NAEFS, are the
farthest north solutions. If this were to occur, moisture will
once again increase--and heavier rainfall will be a possibility.
By Friday, high pressure will follow Hector--and rain chances will
decrease.
