Water vapor imagery revealed a broad ridge over the main Hawaiian islands this morning with two weak lows located to the east and west of the islands. The first low was centered near 19°N 180°W and was developing some cumulus clouds as it moved to the west-southwest at around 25 mph. The second low was centered near 21°N 145°W and was producing some cumulus and cirrus clouds bounded by an area from 26°N 141°W to 19°N 141°W to 22°N 145°W to 26°N 141°W. Otherwise, variable high clouds have spread northeastward from the inter tropical convergence zone within 175 miles of a line from 10°N 180°W to Johnston island. Also, variable high clouds north of a line from 25°N 180°W to 30°N 164°W were working their way southward as they wrapped around the southeast side of a ridge.

Cloud cover across Hawaiian waters consisted mainly of marine stratocumuli and low to middle cloud layers, though individual small cumuli also were present throughout. The greatest concentration of clouds occurred in the nearly solid overcast east of the curve from 29°N 140°W to 19°N 152°W to 16°N 140°W. These clouds generally moved toward the west at 15 miles an hour and rose to heights of 7000 to 10000 feet.

Across the main Hawaiian islands, stratocumulus and cumulus clouds were moving through the area producing mostly cloudy conditions and scattered light showers. The clouds were moving to the west at around 15 miles per hour with tops near 10000 feet.
