Hawaiian Islands Satellite Interpretation Message
Sat, 09 Oct 2010 00:30:00 -0500
Based on data through 0500 UTC October 09 2010.
The satellite imagery of the main Hawaiian islands at sunset shows a couple of pools of broken low clouds located over the leeward coastal waters of Kauai, that is affecting Niihau as well, and the waters off the Waianae coast of Oahu. These clouds are the extension from interior Kauai and the Waianae district of Oahu respectively. There are also some minor, locally broken low clouds over the Koolau mountains of Oahu, the northeast corner of Molokai and windward Maui. Clear to scattered clouds predominates the windward waters of Kauai and Oahu and waters around Maui county.
As for the Big Island, broken coverage continued over the lower slopes and coastal sections of that island. The waters off the Kona coast is mostly clear, however, satellite imagery shows the leading edge of an area of very loose shower bearing clouds advancing on Cape Kumukahi and the Hamakua coast. This shower area is 200 miles long.
The low clouds are moving from east to west at around 15 mph.
Elsewhere on the satellite imagery, a frontal band is located 660 miles north northwest of Kauai. It is advancing south and southeast at 15 mph. The frontal band has a width of 130 miles.
High level cirrus clouds covered the area between Kauai and the dateline. The cirrus appears to dissipate upon nearing Kauai.
A rather large shower area is passing south of the Big Island which has a length of 800 miles, from 150°W to 165°W.
A couple of hundred miles to the south of this shower area is the intertropical convergence zone /itcz/. The axis of the ITCZ is from 9.5°N 140°W to 9.5°N 160°W to 11.5°N 170°W to 08°N 177°W. Scattered moderate to strong thunderstorms are located within 120 miles either side of the ITCZ but concentrated east of 160°W and west of 170°W.
