Hawaiian Islands Satellite Interpretation Message

Hawaiian Islands Satellite Interpretation Message
Fri, 17 Dec 2010 12:30:00 -0600

Based on data through 1800 UTC December 17 2010.

A broad low pressure system centered about 1200 miles west of Kauai is the most predominate weather feature seen in satellite imagery. A broad swath of layred clouds with isolated pockets of deep convection is seen on the east side of this low pressure system. Some high cirrus clouds on the far east side of this swath of clouds is occasionally moving over portions of the state especially in the vicinity of Kauai. This broad swath of clouds then streams off toward the east eventually reaching the coast of California.

Water vapor imagery also shows an upper low spinning a few hundred miles to the southeast of the Big Island. Isolated thunderstorms are seen pulsing near the center of the upper low as well as along the ITCZ on the south side of the upper low. This upper low appears to be drifting slowly off to the east.

Low cloud coverage over the islands this morning was rather sparse. Just a few patches of low clouds are seen over the Koolau summits, the southeast slopes of Haleakala, and over portions of the Puna district on the Big Island. To the east of the Big Island lies a broad field of scattered to broken low clouds that are moving off slowly toward the west.
