Based on data through 7:00 pm Aug 28 2015 HST


Hurricane Ignacio was about 720 miles east-southeast of Hilo. It was moving northwest toward the Hawaiian islands near 8 miles an hour. Layered clouds with embedded cumulonimbus clouds were in the area from 11°N to 19°N between 142°W and 148°W. The highest tops of these thunderstorms were estimated to be about 54 thousand feet. A cirrus shield extends out 500 miles from the center.

Tropical storm Kilo was about 980 miles west southwest of Honolulu. It was moving west near 9 miles an hour. Layered clouds with embedded cumulonimbus clouds were in the area from 15°N to 19°N between 170°W and 175°W. The highest tops of these thunderstorms were estimated to be about 56 thousand feet. A cirrus shield extends out 325 miles from the center.

North of tropical storm Kilo was an upper level low centered near 27°N 168°W. Layered clouds with isolated embedded cumulonimbus clouds were located in an area from 26°N and 30°N between 160°W and 171°W. The highest tops of these thunderstorms were estimated to be about 57 thousand feet. A cirrus shield extends out 325 miles from the center. South and west of this system were broken to overcast cirrus clouds extending west 180°E.

A surface trough was located along a line from 15°N 159°W to 10°N 165°W with scattered cumulonimbus clouds within 150 miles of this line. The thunderstorms were rising to heights of 48 thousand feet.

In the vicinity of the main Hawaiian islands, stratocumulus and cumulus clouds with tops to between 6 and 10 thousand feet were moving to the west-southwest around 10 miles per hour. Also, this scattered cirrus was moving to the east at 20 miles per hour. At 0500 UTC, Niihau, Kauai, Lanai and Kahoolawe were cloudy. Oahu was mostly clear over the central valley into downtown Honolulu with mostly cloudy conditions elsewhere. Molokai and Maui were mostly cloudy. Over the Big Island it was mostly cloudy, except along coastal area in the north Kohala, Hilo and Puna districts.

The low clouds near the islands were moving west near 10 miles an hour. These light winds and daytime heating were allowing convective clouds to form over parts of the islands, in conjunction with sea breeze convergence.
