Two tropical systems continue to occupy the central Pacific area, one on either side of the Hawaiian islands. But only one remains a threat to the state. Hurricane Kilo was near 18°N 175°W and moving away toward the west. Hurricane Ignacio was near 16°N 147°W and moving northwest toward the islands.
Both tropical cyclones were proudly displaying an eye at their center, an indication of how well formed and strong they were at this time. The swath of strong thunderstorms wrapped around both of these systems rose to between 50000 and 55000 feet.
A cluster of thunderstorms about 500 miles south-southwest of Kauai was associated with a weak trough of low pressure. The trough axis extended from 15°N 162°W to 12°N 163°W. The trough was drifting west near 10 miles an hour. Highest storm tops were around 47000 feet.
Meanwhile, trade winds continued to caress the islands this morning, returning yesterday after a long absence. The trade were carrying a steady supply of scattered to broken patches and small clusters of low clouds into the islands from the northeast. However, at 8 am, skies remained mostly sunny across the island chain. The cloudiest area was over east Molokai with insignificant amounts of clouds being observed elsewhere.
A 30-35 miles wide plume of overcast, showery low clouds extended 225 miles southwest from the south Kona coast. And far to the northwest, an upper level low was centered near 26°N 173°W. It was moving slowly southeastward. A handful of isolated thunderstorms were forming in the area between 26°N 160°W and 31°N 172°W due to that upper low and another one near 30°N 165°W that was nearly stationary.
