Based on data through 2:00 am Oct 13 2015 HST

As of 200 am HST, tropical storm Nora was centered near 13.3°N 147.6°W, about 590 miles southeast of Hilo, moving toward the west- northwest around 10 mph. Broken to overcast layered clouds and numerous cumulonimbus clouds, CB, continued to develop within 300 miles of the center in the northeast quadrant of the storm with showery broken to overcast low clouds elsewhere from 12°N to 18°N between 140°W and 152°W.

An area of broken to overcast layered clouds with embedded thunderstorms associated with the inter-tropical convergence zone were depicted between 9°N and 13°N from 165°W to the international date line. Maximum cloud tops associated with these storms were extending as high as 50 to 55 thousand feet. Cloud motion was toward the west at 10 to 20 mph.

A narrow band of low clouds associated with a frontal boundary extended southwest from 30°N 155°W to around 151 miles northwest of Kauai, then west-southwest to the date line around 25°N. Layered clouds were depicted along this band north of 25°N with mostly low- level cumulus clouds along the band south of 25°N. This band continued to track toward the east north of 25°N and toward the east- southeast around 10 mph.

Layered clouds with a few embedded towering cumulus clouds associated with a north to south oriented surface trough continued to impact the main Hawaiian islands, especially from Oahu to Maui. Maximum cloud tops associated with the towering cumulus clouds extended to around 30 to 35 thousand feet, which were mostly located just east of Oahu. Scattered to broken low clouds were depicted over Kauai and the Big Island.
