Hawaiian Islands Satellite Interpretation Message
Tue, 07 Sep 2010 07:00:00 -0500
Based on data through 1130 UTC September 07 2010.
An area of broken showery low clouds has been moving over the aloha state this early morning, bringing ceilings mainly to windward coastal, mauka, and windward upslope sections on the individual isles. However, leeward areas of the smaller islands are seeing broken cloudiness from time to time as well. Low ceilings have also been occasionally affecting coastal and lower upslope portions of north and south Kona on the Big Island. Low cloud movement is from the east-northeast at 15 to 20 mph across the island chain.
Conditions are predominantly scattered to broken in waters immediately surrounding the islands, including the channels. Much of the cloudiness exists from the Kauai channel through the Kaiwi Channel to just east of Maui and northeast of the Big Island. On the other hand, areas of clear to partly cloudy skies are evident south of Maui, south and southwest of Oahu, and southeast clockwise through north of Kauai.
An upper low is approximately 850 miles north-northeast of Honolulu and has been pushing west near 10 mph over the past 6 to 12 hours. Another upper low is about 900 miles west-northwest of Kauai and has been drifting slowly toward the south-southwest. A trough stretches to the southwest of the second low and has been nearly stationary. Each feature is helping to ignite isolated thunderstorms in its vicinity.
An east-northeast to west-southwest oriented surface trough remains nearly stationary far southeast of the Big Island. Unorganized showers and isolated thunderstorms are associated with the system. Most of the convection is currently bounded by 16°N 142°W to 09°N 132°W to 07°N 135°W to 10°N 155°W to 15°N 149°W to 16°N 142°W.
