Satellite imagery shows the remnants of Celia still with some
convection to the northwest of the state. Deeper moisture pluming
up into the system as per blended precipitable water loops
suggests fuel lingers for some island showers today, especially
over the western islands. Guidance agrees that trades rebound over
the next few days as a shortwave ridge settles over Hawaii to set
a pattern with limited windward showers. This occurs as another
tropical system approaches from the east. The National Hurricane
Center forecast tracks Tropical Storm Darby just to the northeast
of the islands this weekend. Suspect deeper moisture pooling over
the islands underneath the system should fuel another period with
enhanced shower activity that lingers and shifts gradually west
early-mid next week. The Central Pacific Huuricane Center takes
over forecast responsibility for Darby later today.
