Issued: Jan 25, 2015 2:30 PM HST


Based on data through 2:00 pm Jan 25 2015 HST


Latest visible and infrared satellite imagery shows a decaying stationary frontal boundary located just SE of the aloha state.

Most areas of the Big Island below 9 thousand feet are covered by broken to overcast low clouds. Showers can be observed over the N Kohala district, the SE slopes of Mauna Loa, Hilo and vicinity, and over leeward areas from Kona village resort to Captain Cook. On Maui county, broken to overcast low clouds and showers cover the windward areas of Maui, Molokai, and Lanai. Broken low clouds cover most of the rest of Maui and Molokai. Streaming low clouds from leeward Haleakala are bringing broken coverage into Kahoolawe. On Oahu, overcast low clouds and showers cover the length of the Koolau mountains and the windward coastline. Broken to locally overcast patches of low clouds can be observed over the Waianae range and leeward areas from Kapolei to makua valley. On Kauai county, broken to overcast low clouds prevail with showers still affecting leeward areas of Kauai from Kalaheo to mana.

Meanwhile, the aforementioned decaying frontal boundary stretches far NE from the island chain from 19.0°N 154.1°W to 23.9°N 145.3°W to 30.0°N 140.0°W, which is marked by a 200 mile-wide low cloud band. An associated area of layered clouds with sporadic thunderstorm activity cover the area N of 22°N between 140°W to 143°W, with cloud tops near 40 thousand feet.

Elsewhere, broken to locally overcast cumulus and stratocumulus clouds cover much of the area N of 20°N between 140°W to 175°W with individual cloud elements moving mainly to the S and SW at 15 to 20 mph. S of 20°N, mainly scattered to locally broken low clouds prevail with cloud motion to the SW and W at around 15 mph.

Far S of the islands, a cluster of thunderstorms can be observed near the intertropical convergence zone, or ITCZ, centered around 07.8°N 169.5°W, or about 1180 miles SW of Oahu. Cloud tops in these thunderstorms are pushing 40 thousand feet.
