A weak, disorganized trade wind flow remained unsettled across the Hawaiian islands. High pressure far north of the state was fairly weak. And a surface low pressure system, the remnant of once hurricane Marie, Sat just about 1550 miles northeast of Honolulu.
Several weak low cloud circulations or vortices passing through the region were helping to disrupt the trade wind flow. One low cloud circulation was centered about 60 miles northeast of Kahului Maui. Another was near 23°N 150°W. And another was centered further north near 31°N 155°W.
A large cluster of showery, broken low clouds associated with the cloud circulation just northeast of Maui covered much of the area from 21°N to 23°N between 153°W and 156°W. A large cluster of broken to overcast low clouds, most of them associated with a Big Island cloud plume, covered much of the area from 18°N to 19°N between 156°W and 158°W.
At 8 am, the south tip of the Big Island was mostly cloudy, as was the northeast coast of Maui. A smattering of low clouds lined the Koolau range on Oahu and even less was seen over east Kauai. The rest of the state was mostly sunny. Low clouds in the area were moving west at just under 15 miles an hour. However, those clouds just west of the circulation center near Maui were flowing southwestward into the valley isle.
Water vapor imagery showed an upper low near 31°N 163°W. The low was nearly stationary. A weak trough extended from the low through 30°N 162°W to 26°N 167°W. A few, small, relatively weak, isolated, thunderstorms were forming just southeast of the low near 29°N 161°W.
