Hawaiian Islands Satellite Interpretation Message
Fri, 29 Oct 2010 07:30:00 -0500
Based on data through 1200 UTC October 29 2010.
The most significant cloud feature seen in the vicinity of the main Hawaiian islands is an east to west oriented band of showery looking clouds which can best be described as the decaying remnants of an old cold front. This cloud band has been moving into windward sections of Kauai and Oahu over the past several hours with the southern edge now beginning to move into Maui county. The band is moving toward the south southwest at around 15 mph while individual clouds along the band and generally moving toward the west southwest at around 2O mph. The band is between 150 and 180 miles wide. Cloud tops are generally running at between 7000 feet and 10000 feet.
As far as cloud coverage over the islands themselves, the above mentioned band is causing mostly cloudy skies over most of Kauai and Oahu including the surrounding coastal waters. As mentioned above the southern edge is moving into windward portions of Molokai and Maui. Scattered low clouds are also seen over portions of the Big Island mainly the windward slopes as well as portions of the Kona coast and adjacent coastal waters.
Water vapor imagery shows a broad upper level trough centered several hundred miles to the west of Kauai. Some high cirrus clouds are being drawn up from the south on the east side of this trough. The northern extent of these high clouds are occasionally moving over portions of the Big Island but the vast majority of them remain just to the south and east of the state. These high clouds have there origins from deep convection along the ITCZ which is basically centered along 10°N.
