Issued: Oct 24, 2014 8:30 AM HST


Based on data through 8:00 am Oct 24 2014 HST


The main Hawaiian islands lie under a relatively stable trade wind flow this morning. A batch of moisture moved onto the islands overnight and remains hung up on Kauai and Oahu. Broken low clouds prevail on windward slopes of these islands with only few low clouds making across to leeward areas. Scattered to broken cumulus clouds are noted across windward slopes of Maui county and the Big Island, while leeward sections of these islands are mostly clear.

The moisture over Kauai extends to the northeast to 24°N 158°W as a 50 mile-wide band of broken cumulus clouds, then turns to the east-southeast and runs for 800 miles to 21°N 145°W. The band is travelling along the trade wind flow, which based on early morning low cloud motions near the islands is moving from the east-northeast around 20 mph.

Farther north, a cold front is located nearly 300 miles northeast of the state. The front is comprised of a 100 mile-wide band of broken to overcast low clouds centered along 26°N 140°W, 25°N 145°W, 26°N 155°W, and 30°N 160°W. The front is travelling to the south at 15 mph to the west of 145°W, and to the southeast near 20 mph to the east of 145°W.

Tropical storm Ana continues to move toward the north-northeast around 10 mph about 250 miles north-northeast of laysan island. Scattered thunderstorms rise as high as 48000 ft within roughly 125 miles of the center. A trailing convergence band to the south of Ana is triggering isolated thunderstorms along 28°N 166°W, 24°N 167°W, and 13°N 174°W.

Farther west, a slow-moving front is located near Midway and pearl and hermes atoll. A 125 mile-wide area of isolated thunderstorms is found from 28°N to 23°N west of 174°W.
