Tropical Storm Khanun

Recommended Posts

Tropical Depression 08W has formed approximately 160 miles south-southwest of Iwo To, Japan. The depression has a well defined LLC but most of the convection resides to the south of this circulation. Due to the sprawling nature of 08W, strengthening will probably be slow. However, conditions are favourable for intensification, with low shear and warm sea temps expected to persist. The depression is moving westwards along the southern side of a ridge over Japan, but will turn to the north as it begins to round onto the western side of the ridge. This puts South Korea at risk from 08W, and a landfall is expected here in a few days time.

08W has become Tropical Storm Khanun, with intensity now at 35kts. The LLC has become better defined, but convection is not as impressive. Nevertheless, Khanun is in low shear and warm sea temps, so some more intensification is expected. Landfall is still forecast to occur in South Korea in around 48hrs time.

Khanun has strengthened to 50kts. A little further strengthening is expected before Khanun swings to the north and reaches cooler waters. As Coast's post decribes above however, Khanun will still be packing tropical storm force winds as it brushes South Korea. The track from JTWC has shifted a little westwards this morning as the ridge to the north has moved westwards a little in tandem with Khanun, delaying the poleward turn. Khanun will still bring heavy rains and strong winds to South Korea as the storm brushes the country but final landfall should now occur on North Korea. At this point however, Khanun should be a weakening tropical depression as cool sea temps rob Khanun of it's energy.

Khanun did not strengthen any further. The storm has now made landfall in South Korea and is unravelling over land. Strong winds and heavy rains will be felt over North and South Korea for the next 24hrs or so before Khanun moves out into the Sea of Japan, where dissipation over cold water will occur.
