Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 809 AM EDT Thu Sep 03 2015 Valid 00Z Fri Sep 04 2015 - 00Z Fri Sep 11 2015 Over the coming few days Hurricane Ignacio will continue on a northward track away from the islands while Hurricane Jimena, currently about 12 degrees of longitude east of the Big Island, should proceed on a north-northwestward track. Consult Central Pacific Hurricane Center products for the latest information regarding Ignacio and Jimena. A lingering band of moisture to the south of Ignacio, with precipitable water values of at least 2 inches, may support a continued potential for pockets of locally heavy rainfall especially over the western islands into the weekend. By next Mon-Wed most of the state should see relatively drier conditions. Weak surface ridging to the west/southwest of Jimena should support light to moderate winds from the northeast or east, with any shower activity likely to have a diurnal and possibly sea/land breeze component. The track of Jimena will have to be monitored late in the period and beyond. After tracking to the north-northwest into day 5 Tue, most guidance expects the ridge to the north to evolve in such a way as to bring Jimena back to the southwest closer to the islands. Current confidence is low in a specific solution as the 00z ECMWF mean is closer to the 00z/06z GFS runs that reach closer to the islands while the 00z GEFS mean holds the system at least as far back if not to a greater extent than the 00z ECMWF run. Would recommend a compromise among all of these solutions if a deterministic forecast is required. Rausch
