Hawaiian Islands Satellite Interpretation Message
Sat, 25 Dec 2010 06:30:00 -0600
Based on data through 1200 UTC December 25 2010.
A slowly disintegrating band of deep layered clouds with embedded isolated towering cumuli extended across Hawaiian waters between the line from 25°N 170°W to 30°N 166°W, and the curve from 20°N 180 to 24°N 161°W to 30°N 151°W. Thin layered high clouds also partly obscured lower features up to about 350 miles southeast from the leading edge of the main cloud band. This feature as a whole drifted east slowly.
Another band of low to middle cloud layers associated with a second front extended across Hawaiian waters within 120 miles of the curve from 30°N 163°W to 23°N 146°W to 23°N 140°W and further northeast. Densely packed cold-air cumuli prevailed between this band and 30°N. This feature moved south slowly.
To the south, light thunderstorm activity continued in the ITCZ between 13°N and 06°N. Layered high to middle debris clouds from this and earlier convection partly to mostly obscured lower features between 04°N and the curve from 14°N 180 to 15°N 175°W to 10°N 160°W to 19°N 149°W to 18°N 140°W.
Isolated thunderstorms developed within 75 miles of the point 17°N 158°W. Layered high to middle debris clouds from this and earlier convection partly obscured lower features within 75 miles of the line from 17°N 158°W to 16°N 154°W.
Otherwise, cloud cover across Hawaiian waters consisted mainly of small unorganized clumps of marine cumulus and stratocumulus. These clouds generally drifted west slowly. They rose mostly to heights of 5000 to 7000 feet, though taller cumuli approached 15000 feet.
Across the main Hawaiian islands, cloud cover consisted mostly of layered debris clouds from towering cumuli just offshore from the northwest coast of Kauai, and along the southeast clockwise through west coasts of the Big Island. Few clouds were present otherwise. Radar data from near the islands showed scattered showers along the northwest coast of Kauai, and offshore to the southeast clockwise through west of the Big Island. The lower clouds varied considerably in height from 5000 to 15000 feet, while the towering cumuli and their debris clouds approached 25000 feet.
