Hawaiian Islands Satellite Interpretation Message

Hawaiian Islands Satellite Interpretation Message

Based on data through 1200 UTC August 25 2016.
Posted: August 25, 2016, 12:30 pm

Overnight infrared satellite images show sparse cloud cover over the main Hawaiian islands. Scattered low cloud motions around the Big Island and Maui indicate that trade winds are returning to eastern sections of the state. These clouds are moving to the west at 10 to 15 mph. Weaker southeast flow prevails over western sections of the state. Only few to scattered cumulus /cu/ and stratocumulus /sc/ are noted over most of the islands, with small patches of broken low clouds present over Lanai and windward Oahu. An isolated cumulonimbus /cb/ is located about 190 miles southwest of Honolulu, with estimated tops up to 40 thousand feet. Otherwise, more typical conditions prevail after the unstable conditions of the past few days around the Hawaiian islands, with cloud tops generally ranging from 6 to 9 thousand feet.

A deep upper level trough is located over the far northwestern Hawaiian islands, and extends as far south as 15°N between 170°W and 180. A surface low along the eastern side of the upper level trough is centered near 38°N 166°W. An area of layered mid and upper level cloudiness is rotating through the upper level trough, along and 150 miles either side of a line from 25°N 175°W to 28°N 170°W to 30°N 168°W. No significant deep convection is noted within this area.

Areas of broken cu with isolated embedded towering cumulus are present along and 300 miles either side of a line from 21°N 168°W to 30°N 162°W. Highest estimated tops in this region are around 43 thousand feet.

Another area of overcast layered cloudiness with isolated embedded cumulonimbus /cb/ clouds is located at the base of the upper trough, covering the waters from 14°N to 19°N and between 175°W and 180. Highest estimated tops are near 48 thousand feet.

A weak surface trough is centered far southeast of the Hawaiian islands near 12°N 150°W. Scattered CB associated with this low are present within 300 miles of the low center. Highest estimated tops in this area extend up to 50 thousand feet. This trough is moving slowly to the west.

Over the remainder of the central north Pacific, few to scattered cu and sc prevail, except for north of 18°N and east of 150°W where areas of broken sc are moving westward at 10 to 15 mph within trade wind flow.
