Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 739 AM EDT Sat Jul 09 2016 Valid 00Z Sun Jul 10 2016 - 00Z Sun Jul 17 2016 The 9/00Z GFS/GEFS and ECENS/ECMWF have displayed good run-to-run continuity and is very supportive of the Hawai'i forecast philosophy and sensible weather outlook. Both guidance packages have similar outcomes for Blas. And for a day 6-7 forecast --- generally provide an excellent depiction of Celia's migratory path westward of 140W longitude. Given the above average model performance, an "either/or both" preference seems appropriate today for the Subtropical Pacific Consult the National Hurricane Center for all the latest forecast information and guidance concerning Blas and Celia.
