...Kona Storm...

A Kona low is progged to make a loop about the Hawai'ian islands
tonight through Thursday, before being kicked to the northeast as
another impulse drops down from the main band of westerlies this
weekend. For now it appears that the second impulse will forge
another eddy northeast of the state, though the current system was
originally forecast to close off away from Hawai'i as well. Time
will tell. A third(!) vortex may drop into the region by the
middle of next week. If all three eddies were to center on the
state, rainfall totals would be astronomical.

The current Kona low is capable of producing several inches of
rainfall throughout the island chain, with gusty shifting winds.
Any westward shift in the looping of the storm would result in
significantly higher rainfall amounts. The rainfall potential over
the next weeks very much depends on the track of any subsequent
vortices.
