Hawaiian Islands Satellite Interpretation Message
Mon, 13 Dec 2010 12:00:00 -0600
Based on data through 1730 UTC December 13 2010.
Low ceilings, some with embedded showers, are prevalent in coastal and upslope areas of the Kau, Puna, and Hilo districts on the Big Island this morning, and to a lesser extent Hamakua. Broken low cloudiness has also been affecting, at least from time to time, upslope sections of east Maui, and mauka portions of west Maui, Molokai and Lanai. Skies are otherwise clear to partly cloudy. Low cloud movement is near 15 mph across the aloha state, from the east-southeast near the Big Island and veering to south- southeast moving up the chain to Kauai.
A band of broken showery low cloudiness, with embedded towering cumulus clouds, stretches northeastward from the Big Island and is heading northwest with the prevailing low-level flow. The band then extends just east of the isle and continues off to the south. Smaller areas of scattered to broken low clouds exist west of Kau and south Kona on the Big Island, north of Maui county, south clockwise through west of Oahu, and north of Kauai. Conditions are clear to scattered elsewhere in the adjacent coastal waters.
A line of showers and thunderstorms ahead of a front is west of the islands and has been pushing east near 15 mph over the past six hours. The leading edge of the convection is approximately 450 miles west-northwest of Kauai as of bulletin time, with most of the activity currently within 90 miles either side of a line from 30°N 163°W to 21°N 170°W to 17°N 180°.
Showers and thunderstorms are firing along the intertropical convergence zone far south of Hawaii, though most of the cells are weak and widely separated. The convection is mainly found from 06.5°N to 10°N between 136°W and 165°W, and from 06.5°N to 09.5°N west of 174°W.
