Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 749 AM EDT Wed Jul 08 2015 Valid 00Z Thu Jul 09 2015 - 00Z Thu Jul 16 2015 ...Tropical disturbance advancing towards Hawai'i... The 8/00Z forecast cycle guidance (ECENS and GEFS) and their deterministic runs continue to provide a solid forecast through the mid-range period. Not only across the mid-latitude north Pacific--- but also in the Tropics and Subtropics. Mass fields forecasts place the bulk of the 500mb vorticity associated with 'Four-e' between 150W-160W @ 10/12Z and by day 6 (14/12Z) have the surface wave in a very reasonable position --- near 29N 172W. A second disturbance invof 11W 175W is slotted coincidentally--- at lower latitude --- migrating westward towards the Marshall Islands--- but holding a rather steady storm track which remains between 11N and 15N latitude into day 6. Please refer to the Central Pacific Hurricane Center (CPHC) for the most recent information and forecasts concerning 'Four-e'. Sensible weather concerns --- based on the most recent CPHC forecast advisory (08/0830Z)--- would place the higher rainfall amounts on the windward (east/northeast) shores of Kauai between 10/12Z and 12/12Z. But overall, the deterministic GFS/ECMWF qpf solutions keep the bulk of the deeper convection and heavy rainfall offshore and well north of Hawai'i. Vojtesak
