Hawaiian Islands Satellite Interpretation Message
Sat, 16 Oct 2010 13:30:00 -0500
Based on data through 1800 UTC October 16 2010.
As of 8 am, visible imagery showed scattered clouds over northeast facing mountain slopes of the smaller islands. Elsewhere over the smaller islands, including all of Lanai, skies were clear or there were isolated clouds. Windward coastal waters northeast of the smaller islands had scattered clouds, except for broken clouds headed towards Kauai and Maui. Skies over leeward waters were almost free of low clouds.
The windward side of the Big Island southeast of Laupahoehoe had the greatest concentration of low clouds, i.e, broken to overcast. The rest of the island had only a few low clouds.
Water vapor imagery showed an upper level low centered west of Hawaii near 22°N 172°W and a broad upper level trough extending to the northeast through 30°N 155°W. The low was triggering isolated thunderstorms in an area from 12°N to 30°N between 162°W and 175°W. The closest thunderstorms were 200 miles west southwest of Kauai. Thin high clouds were moving over the islands in the southwesterly flow east of the low and trough.
Low clouds were moving to the west southwest at around 20 mph. Cloud tops were at or below 9000 feet.
