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. In addition, the 00Z ECMWF is trending
northward and stronger. 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.
