Based on data through 2:00 pm Sep 22 2014 HST


High pressure entering the central Pacific from the west has formed a ridge that extends along 25°N. South of the ridge, scattered to broken low clouds are pushing westward at 10 to 20 mph. North of the ridge to 30°N, broken low clouds are moving 10 mph toward the east.

An upper level low centered near 18°N 167°W is strong enough to set off a few thunderstorms in the area enclosed by 18°N and 21°N between 165°W and 170°W. The thunderstorms are moving 15 mph toward the west with tops reaching up to 44 thousand feet.

A low level trough near 12°N 150°W is producing some towering cumulus with isolated thunderstorms as it moves west at 15 mph. Tops are reaching as high as 42 thousand feet and extend as far north as 15°N.

Over Hawaii, windward Big Island areas have mostly cloudy skies while the smaller island windward areas are partly cloudy. Leeward slopes on the Big Island are cloudy from Kailua Kona to south pount and along the southeast slopes. The leeward slopes of Haleakala also are covered with low clouds. Leeward areas elsewhere are mostly clear to partly cloudy.

In the deep tropics, scattered thunderstorms are found from 150°W to the dateline with the highest tops firing to 50 thousand feet.
