Issued: Sep 04, 2015 2:30 AM HST


Based on data through 2:00 am Sep 04 2015 HST


As of 11 pm HST Wednesday, tropical cyclone Ignacio was located about 785 miles north northwest of Oahu. Ignacio was tracking toward the north northwest at 13 miles per hour. Layered clouds with embedded thunderstorms were observed between 27.5°N to 30.0°N and 156.7°W to 164.7°W. Cloud tops in this area were reaching 31 thousand feet. Hurricane Jimena was located about 675 miles east of the Big Island of Hawaii, tracking northwest at 5 miles per hour. Layered clouds with embedded thunderstorms were covering the area between 15.7°N to 24.6°N and 140.0°W to 149.2°W. Cloud tops ranged from 45 to 52 thousand feet, highest near the center of Jimena.

Layered clouds associated with typhoon Kilo were covering the area between 176.0°W to 180 and 22.0°N to 30.0°N. Highest cloud tops were pushing 32 thousand feet. This area of clouds was slowly shifting westward as Kilo continued to track away from the discussion area.

Closer to the islands, scattered low clouds prevailed over the Big Island. On Maui county, scattered low clouds were moving across Maui and Lanai, while bands of broken low clouds were observed over the western coastline of Molokai. On Oahu, a swath of broken low and mid level clouds is obscuring low level features. On Kauai county, mainly scattered low clouds prevail.

Elsewhere, scattered to broken low clouds covered most of the area north of 10°N and between the three aforementioned tropical cyclones. Cloud motion is variable, erratic at times as low level flow remains disrupted by the influence of the hurricanes. A cluster of thunderstorms was centered around 18.9°N 159.6°W, or about 190 miles SW of Honolulu. Cloud tops were reaching 35 thousand feet.

Far S of the islands, a large area of deep convection and thunderstorms near the intertropical convergence zone, or ITCZ, was extending from near the equator to 10.0°N and 150.0°W to 170.0°W. Cloud tops in these thunderstorms ranged from 45 to 54 thousand feet.
