Corrected spelling error based on data through 0000 UTC April 24 2014 water vapor imagery indicates weak upper level low pressure continues over the main Hawaiian islands with a trough extending to the west along 21°N. An upper level high pressure ridge resides east of the islands with an axis along 139°W. Scattered to broken cirrus clouds to the east of a curve from 10°N 157°W to 19°N 150°W to 25°N 160°W to 30°N 155°W are moving from the low into the ridge. These high level clouds are moving to the northeast between 20 and 40 miles per hour and rising to heights around 38000 feet.

At the mid to lower levels, scattered to broken stratocumulus clouds are spread across the area. These clouds are rising to heights between 9000 and 12000 feet and moving to the west around 20 miles per hour. The densest area of the stratocumuli lies north and east of the islands and is partly obscured by the cirrus clouds. The rough boundary of these denser clouds is east of a line from 30°N 140°W to 23°N 160°W to 10°N 147°W.

In the vicinity of the main Hawaiian islands, scattered stratocumulus clouds around the islands are becoming broken to overcast as they push up against the windward slopes. Some of these clouds are being advected across the islands onto the leeward sides. On the Big Island leeward slopes have become broken to overcast as seabreezes are enhancing cloud development. The stratocumulus are rising to heights of 11000 feet. At 0000 UTC Niihau is partly cloudy. Kauai is mostly cloudy over the higher terrain and partly cloudy elsewhere. Oahu and Molokai are mostly cloudy on windward slopes while the leeward sides are mostly sunny. Lanai and Kahoolawe are mostly sunny. Maui is mostly cloudy on windward slopes while the leeward areas are partly cloudy. On the Big Island it is mostly cloudy below 11000 feet with the exception of the south Kohala and the eastern Kau districts where it is mostly sunny.
