A large cyclonic atmospheric gyre near Japan spun up two more tropical storms at the end of the week.\u00a0 The Japan Meteorological Agency named two smaller circulations within the larger gyre Tropical Storm Lionrock and Tropical Storm Kompasu.<\/p>\n
At 2:00 p.m. EDT on Saturday the center of Tropical Storm Kompasu was located at latitude 37.8\u00b0N and longitude 142.3\u00b0E which put it about 75 miles (120 km) east of Sendai, Japan.\u00a0 Kompasu was moving toward the northwest at 26 m.p.h. (42 km\/h).\u00a0 The maximum sustained wind speed was 40 m.p.h. (65 km\/h) and there were wind gusts to 50 m.p.h. (80 km\/h).\u00a0 The minimum surface pressure was 996 mb.<\/p>\n
At 2:00 p.m. EDT on Saturday the center of Tropical Storm Lionrock was located at latitude 30.6\u00b0N and longitude 135.7\u00b0E which put it about 530 miles (860 km) east-northeast of Okinawa.\u00a0 Lionrock was moving toward the west-southwest at 8 m.p.h. (13 km\/h).\u00a0 The maximum sustained wind speed was 40 m.p.h. (65 km\/h) and there were wind gusts to 50 m.p.h. (80 km\/h).\u00a0 The minimum surface pressure was 994 mb.<\/p>\n
Tropical Storm Kompasu is located farther north and it is beginning to make a transition into an extratropical cyclone.\u00a0 Kompasu is moving over water where the Sea Surface Temperature (SST) is near 26\u00b0C, but it is moving rapidly toward cooler SSTs.\u00a0 Most of the thunderstorms are in a single primary rainband that wraps around the southern part of the circulation.\u00a0 An upper level trough west of Japan is pulling southwesterly winds across the top of Tropical Storm Kompasu and the vertical wind shear is increasing.<\/p>\n
The upper level trough is expected to turn Tropical Storm Kompasu toward the northeast.\u00a0 On its anticipated track Tropical Storm Kompasu will move across Hokkaido in about 18 hours.\u00a0 It will bring locally heavy rain and some wind.<\/p>\n
Tropical Storm Lionrock is more well organized.\u00a0 Several spiral bands of thunderstorms are wrapping around the southern and east sides of the center of circulation.\u00a0 There is drier air in the western portion of the circulation and there are few thunderstorms in that part of Lionrock.\u00a0 The thunderstorms east of the center are generating upper level divergence that is pumping mass toward the northeast away from core of Tropical Storm Lionrock.<\/p>\n
Tropical Storm Lionrock is in an environment that is somewhat favorable for additional intensification.\u00a0 It is moving over water where the SST is near 30\u00b0C.\u00a0 The upper level trough west of Japan is generating some vertical wind shear.\u00a0 The drier air in the western part of the circulation will also inhibit intensification, but Lionrock could gradually get better organized.\u00a0 Upper level outflow from stronger Tropical Storm Mindulle, which is southwest of Lionrock, could produce enough vertical wind shear to weaken Lionrock at times.<\/p>\n
The large atmospheric gyre is steering Tropical Storm Lionrock toward the west-southwest.\u00a0 Lionrock could be pulled more toward the south as the larger, stronger Tropical Storm Mindulle passes east of it.\u00a0 Tropical Storm Lionrock is expected to remain south of Japan during the next several days.\u00a0 An alternative scenario would be for Tropical Storm Mindulle to intensify into a typhoon and grow large enough to absorb the circulation of Lionrock.<\/p>\n","protected":false},"excerpt":{"rendered":"
