Issued: Oct 22, 2014 8:30 AM HST

Based on data through 8:00 am Oct 22 2014 HST

Tropical storm Ana is located about 530 miles west of Lihue at 8 am HST, and is moving to the northwest at 10 mph. Cumulonimbus clouds with tops to 50000 feet are located within 150 miles northeast of the center. Additional cumulonimbus clouds with tops to 44000 ft are located within 300 miles to the north through east of the center. Another band of isolated cumulonimbus clouds is located farther to the southeast, generally between 163°W and 165°W north of 19°N.

A band of showery low clouds is located to the east of Ana, and extends southeastward across windward coastal waters of the main Hawaiian islands. This band is up to 150 miles wide, and is located south of a line from 27°N 162°W to 21°N 153°W. Isolated cumulonimbus clouds are embedded within the northwestern portion of this band, generally west of 159°W. Cloud tops extend up to 43000 ft. Otherwise the band is composed primarily of showery open cell cumulus elements, with embedded towering cumulus elements extending up to 15000 ft.

Going from island to island, a narrow band of broken mid-level clouds covers Niihau, and extends 40 miles offshore to the southeast. Broken low clouds cover the interior of Kauai. A band of high clouds is located over the Kauai channel, but are thin enough for low cloud features to be visible. Broken to overcast low clouds cover the slopes of the Koolau range on Oahu. Broken low clouds cover northeastern Molokai northeast of pukoo, and also northern coastal sections of Lanai. Broken low clouds cover the interior of the west Maui mountains, and windward slopes of Haleakala from Paia to Hana to Kipahulu below 4000 ft. Additional low clouds are located from Kipahulu to Ulupalakua, which also extend offshore across Kahoolawe.

The Big Island is mostly clear. A narrow band of low clouds covers a portion of north Kona district, extending across mainly Keahole Point. The large cloud band mentioned above over windward coastal waters is about 30 miles northeast and east of the Big Island. This band is moving to the west at 10 mph.
