Rainfall associated with tropical depression Kilo recently dumped heavy rain in some areas of the state of Hawaii. Tropical depression Kilo changed course to move away from the Hawaiian Islands so it is no longer a threat but has recently been more energetic. The GPM core observatory satellite flew over on August 25, 2015 at 0121 UTC as Kilo approached Johnson Atoll and found that rainfall intensity had recently increased and the tropical depression's storm tops were very tall.

GPM's Dual-Frequency Precipitation Radar (DPR) discovered that rain was falling at a rate of almost 65 mm (2.6 inches) per hour and storm tops were measured at altitudes of over 15.4 km (9.5 miles). The Central Pacific Hurricane Center (CPHC) predicts that Kilo will strengthen again into a tropical storm as it moves harmlessly westward over the open waters of the central Pacific Ocean.
