Unknown
Extratropical cyclone, remnant low, tropical disturbance, or monsoon depressionDella began as an easterly wave and can be traced as far east as Truk with consistence. Kwajalein shows the passage also, but its track to Truk is indistinct. The eventual track was substantiated by data at Guam and Yap with intensification evident near 15 N and 127 E, seven days after the easterly wave passage at Truk. A surge of moist unstable air from the south was considered as the primary factor in intensification. A parabolic path was followed, with the eye passing over Okinawa. Contrary to climatological data, Della pursued a path across Kyishi rather than the conventional movement along the polar trough to the south of Japan. Della moved into the Sea of Japan and became extratropical four days after it was detected as a typhoon.[4]
