Hawaiian Islands Satellite Interpretation Message
Fri, 01 Oct 2010 07:00:00 -0500
Based on data through 1130 UTC October 01 2010.
A slow-moving surface trough in the area continues to induce scattered to broken, occasionally overcast, low cloudiness and showers over the aloha state and adjacent waters. As of bulletin time, most of the showers are occurring in windward coastal and windward upslope sections of east Maui, and eastern and central parts of Oahu. More showers are evident north and south of Maui county, northwest and south of Oahu, and just west of the Big Island. On the other hand, skies are nearly clear east clockwise through southwest of the Big Island, and directly south of Kauai. Low cloud motion is from the east to slightly south of east near 10 mph from Oahu to the Big Island, and from the east to east- northeast at 15 to 20 mph near Kauai.
A weak front is more than 325 miles north of Kauai and appears to be heading slowly toward the south and southeast. Most of the cloudiness associated with the system is currently north of a line from 30°N 149°W to 27.5°N 158°W to 25.5°N 170°W. The low clouds at the leading edge of the boundary are becoming more diffuse with time.
There has been little change in upper air features, above 25 thousand feet, since last evening. The axis of a north-northeast to south-southwest oriented trough is east of the Big Island and is along a line from 25°N 149°W to 19°N 153°W to 13°N 156°W. The system has remained nearly stationary over the past seven hours, though it has narrowed in the east-west direction. An upper high has remained anchored about 475 miles west of Kauai. This configuration aloft is producing a north flow across the island chain.
Unorganized showers and thunderstorms are igniting along the intertropical convergence zone south of Hawaii. Most of the convection is located from 10°N to 14°N between 145°W and 162°W, and from 04.5°N to 11°N between 162°W and the date line at 180. Some cells are climbing to over 50 thousand feet in the area from 06°N to 09°N between 172°W and 177°W as of this writing.
