Typhoon Koguma weakened on Sunday as it moved over the Western North Pacific Ocean southeast of Japan.\u00a0 At 11:00 p.m. EDT on Sunday the center of Typhoon Koguma was located at latitude 29.0\u00b0N and longitude 147.6\u00b0E which put the center about 655 miles (1060 km) southeast of Tokyo, Japan.\u00a0 Koguma was moving toward the north at 14 m.p.h. (22 km\/h).\u00a0 The maximum sustained wind speed was 115 m.p.h. (1850 km\/h) and there were wind gusts to 145 m.p.h. (235 km\/h).\u00a0 The minimum surface pressure was 954 mb.<\/p>\n
Typhoon Koguma weakened on Sunday, but the structure of Koguma was still intact.\u00a0 A large circular eye with a diameter of 45 miles (75 km) was at the center of Koguma’s circulation.\u00a0 The eye was surrounded by a ring of thunderstorms and the strongest winds were occurring in that ring of storms.\u00a0 Bands of showers and thunderstorms revolved around the center of Koguma\u2019s circulation.\u00a0 Storms near the center of Koguma generated upper level divergence that pumped mass away from the typhoon.\u00a0 The removal of mass in the upper levels was less than the convergence of mass in the lower levels of the atmosphere.\u00a0 So, the surface pressure increased on Sunday.<\/p>\n
The distribution of wind speeds in Typhoon Koguma was fairly symmetrical.\u00a0 Winds to typhoon force extended out 65 miles (105 km) from the center of Koguma\u2019s circulation.\u00a0 Winds to tropical storm force extended out 130 miles (210 km) from the center of Typhoon Koguma.<\/p>\n
The Hurricane Intensity Index (HII) for Typhoon Koguma is 20.6. The Hurricane Size Index (HSI) is 19.6 and the Hurricane Wind Intensity Size Index (HWISI) is 40.2. Typhoon Koguma is similar in intensity to Hurricane Rita when Rita hit southwest Louisiana in 2005.\u00a0 Koguma is not as large as Rita was.<\/p>\n
Typhoon Koguma will move through an environment that will be unfavorable for intensification during the next 24 hours.\u00a0 Koguma will move over water where the Sea Surface Temperatures are near 26\u00b0C.\u00a0 It will move under the eastern side of an upper level trough that is over Japan.\u00a0 The upper level trough will produce southwesterly winds that will blow toward the top of Koguma’s circulation.\u00a0 Those winds will cause moderate vertical wind shear.\u00a0 Moderate vertical wind shear and cooler Sea Surface Temperature will cause Typhoon Koguma to continue to weaken on Monday.<\/p>\n
The upper level trough over Japan will steer Typhoon Koguma toward the northeast during the next 24 hours.\u00a0 On its anticipated track, Typhoon Koguma will stay far to the east of Japan.<\/p>\n","protected":false},"excerpt":{"rendered":"
