The Central Pacific Hurricane Center (CPHC) indicates that
tropical storm Oho is gaining hurricane strength while spinning
just southeast of the Big Island near 15.2N/152.6W at 09 UTC. Oho
is forecast to track north-northeastward to pass just east of the
islands tomorrow before lifting increasingly away from the state.
Tropical moisture associated with Oho is expected to continue to
wrap into the Big Island with this close passage. This may combine
with a lingering old island boundary and terrain to fuel potential
for some locally heavy anchoring rains.

Expect a more limited moisture/rainfall modest trade pattern will
develop across the state in the wake of Oho for the rest of this
week. Models and ensembles then show good clustering with the idea
of digging a mid-upper level trough northwest then potentially
over the islands early next week. This would act to force deeper
lower lattitude moisture back up into the state to fuel some lead
dynamicallly enhanced showers in advance of an associated cold
frontal approach.
