.Synopsis for the Hawaiian offshore waters...
High pressure far NE of the waters will weaken over the next few
days. It will then drift southward closer to the islands this
weekend, and trades will increase once again. Heading into the
weekend, the potential development of a tropical system
southeast of the islands is possible but uncertainty remains as
the system has yet to develop.
