, and the
United States Naval Research Laboratory began tracking the system. On the morning of July 14, the
Japan Meteorological Agency (JMA) upgraded it to a tropical depression. At this point the system moved westward. At 8 pm, the Joint Typhoon Warning Center gave the system a low chance for
tropical cyclogenesis. On the morning of July 15, the JMA issued a gale warning, and the
Central Weather Bureau (CWB) of
Taiwan upgraded it to a tropical depression. On the same day, the
Hong Kong Observatory upgraded the storm to a tropical depression.
At 6:30 am on July 16, the Joint Typhoon Warning Center upgraded the rating to "High" and issued a tropical cyclone warning. The Joint Typhoon Warning Center raised the system to a tropical depression at 2:40 pm, giving the number 06W. At 3 pm on the same day, the Japan Meteorological Agency upgraded it to a tropical storm, naming it ''Danas'', followed by the
China Meteorological Center, the CWB, and

also upgraded it to a tropical storm. The Joint Typhoon Warning Center was upgraded to a tropical storm late that night.
On July 19, the JMA reported that Danas had reached its peak wind speeds with maximum 10-minute
sustained wind

indicator of the intensity of the storm. Within a mature tropical cyclone, it is found within the eyewall at a distance defined as the radius of maximum wind, or RMW. Unl ...
s of 85 km/h (50 mph). Later that day, Danas began to weaken. On July 20, around 13:00 UTC, Danas made landfall in
South Korea as a minimal tropical storm, before weakening into a tropical depression soon afterward. The weakening trend also accelerated on July 20 due to the drop in
sea surface temperatures to near landfall. The Republic of Korea Meteorological Administration downgraded Danas to a tropical depression at 11 am and stopped issuing announcements. At 12:45 UTC on July 21, Danas transitioned into an extratropical low in the
Sea of Japan, and the JMA issued their final advisory on the storm.
