An area of overcast low clouds extends from 140°W to 150°W between 10°N and 25°N. These low clouds are moving west at 15 to 20 mph. Clouds transitions from overcast to scattered west of 150°W as low stratocumulus /sc/ and stratus morph into sc and cumulus. Near the dateline, low clouds veer to the NW as they near a weak cold front oriented from 30°N 172°W to 26°N and the dateline. Along the front, towering cumulus and isolated thunderstorms are forming with highest cloud tops reaching 40 thousand feet.
