Hawaiian Islands Satellite Interpretation Message
Thu, 07 Oct 2010 19:30:00 -0500
Based on data through 0000 UTC October 08 2010.
Visible satellite this afternoon shows afternoon cumulus cloud build ups forming over the land interiors of the main Hawaiian islands. Much of these clouds are anchored across mountains. Inversion heights are between 7 to 8 kft so the peaks on the Big Island and Maui are sunny. On Kauai clouds have formed across the western half of the island while the eastern half is mostly sunny. On Oahu, clouds are formed along the Koolau and Waianae ranges with breaks along the rest of the interior and north and south shores. Molokai and Maui have broken clouds over the entire island. Lanai has clouds across the southern portion of the island with clearing across the north shore. The Big Island has broken to overcast clouds over most of the lower slopes. A few breaks in the clouds are observed around Upolu Point and along the Kohala coast. A few cumulus clouds are moving over the Hawaiian coastal waters and being carried with 15 mph easterly winds. A large patch of cumulus and stratocumulus clouds lies between 40 to 200 miles from the leeward coasts of Oahu through the Big Island. Further upstream to the north and east of the main Hawaiian islands are broken cumulus and stratocumulus clouds associated with the trade winds, particularly north of 20°N and east of 150°W.
Elsewhere, two other bands of clouds are located further to the north and northwest of the main Hawaiian islands. The closest is resulting from a dissipating front and is characterized by a 100 mile wide band along an axis from 30°N 152°W to 24°N 172°W. The second is a cold front with a 125 mile wide band of clouds along an axis from 39°N 148°W to 30°N 164°W to 28°N 177°W.
Far south of Hawaii, unorganized showers and thunderstorms continue across the ITCZ. The main band runs across the central Pacific basin between 08°N and 12°N. A persistent large area of thunderstorms is bounded between 07°N to 14°N and 173°W to 172°E. Storm tops of these thunderstorm cells reach to vertical heights near 52 kft. Cirrus clouds also stem northeastward from this particular storm cluster extending as far north as 19°N and east to 165°W.
