Based on data through 2:00 am Apr 16 2014 HST


Latest water vapor and infrared satellite data shows a weakening upper level low centered around 24.1°N 144.9°W, or about 700 miles NE of the Big Island. This low has remained nearly stationary during the last 6 hours. Isolated thunderstorms are still being observed surrounding the area of the upper low with cloud tops reaching 30 thousand feet.

Closer to the island chain, most of the Big Island remains under mostly clear skies especially at altitudes above 7 thousand feet, while persisting locally broken low clouds can be observed across the Big Island windward coastline. On Maui county, scattered low clouds prevail over windward areas of Maui and Molokai, including the interior W Maui mountains. On Oahu, broken low clouds persist over windward and interior areas with locally overcast low clouds and scattered showers over the Koolau range. Some of the showers are reaching leeward areas of Oahu at times. On Kauai county, broken low clouds prevail over much of Maui with bands of passing showers affecting mostly windward and southern portions of that island.

Elsewhere, scattered to locally broken cumulus and stratocumulus clouds prevail across the area. Individual cloud motion E of 168°W is to the WSW at 15 to 20 mph, and becoming more westerly from 168°W to 180. Far SE of the islands, an 600 mile-wide swath of overcast layered clouds with a few embedded thunderstorms is centered around a line from 15.2°N 140.0°W to 02.0°N 158.6°W. Thunderstorm cloud tops are reaching 44 thousand feet. Cloud motion within the swath of layered clouds is to the NNE at up to 60 mph, but the swath itself is slowly drifting NNE.

Deep convection cover the area near the intertropical convergence zone, or ITCZ, between 01°N to 07°N and 160°W to 180, with thunderstorm cloud tops reaching 54 thousand feet.
