Former Tropical Storm Maliksi strengthened into a typhoon east of Okinawa near Minami Daito Jima late on Saturday. At 11:00 p.m. EDT on Saturday the center of Typhoon Maliksi was located at latitude 25.7°N and longitude 131.7°E which put it about 210 miles (335 km) east of Okinawa. Maliksi was moving toward the northeast at 24 m.p.h. (39 km/h). The maximum sustained wind speed was 75 m.p.h. (120 km/h) and there were wind gusts to 90 m.p.h. (145 km/h). The minimum surface pressure was 970 mb.
The circulation of Typhoon Maliksi became more organized on Saturday. An inner rainband wrapped around the center of circulation and an eye was apparent on satellite images. There were intermittent breaks in the rings of thunderstorms around the eye. Several bands of showers and thunderstorms in the eastern half of the circulation were revolving around the core of the typhoon. Bands west of the center consisted primarily of showers and low clouds. Storms near the core of Maliksi were generating upper level divergence which was pumping mass away to the northeast of the typhoon. The circulation of Typhoon Maliksi was large and winds to tropical storm force extended out about 250 miles (400 km) from the center of circulation.
Typhoon Maliksi will move through an environment favorable for intensification during the next 12 to 24 hours. Maliksi will move over water where the Sea Surface Temperature is near 30°C. An upper level trough to the west of Maliksi will produce southwesterly winds which will blow toward the top of the circulation. Those winds will produce some vertical wind shear, but the shear will not be strong enough to prevent intensification on Sunday. The shear will increase after 18 to 24 hours and that will likely cause Maliksi to start to weaken.
The upper level trough is steering Maliksi toward the northeast and that general motion is expected to continue for another two or three days. Typhoon Maliksi will speed past Minami Daito Jima during the next few hours. On its anticipated track Maliksi will reach some of the islands south of Honshu in about 24 hours. Typhoon Maliksi will produce gusty winds and locally heavy rain.
Tropical Storm Maliksi formed east of Luzon on Thursday while Tropical Storm Ewiniar brought rain to parts of South China. At 8:00 p.m. EDT on Thursday the center of Tropical Storm Maliksi was located at latitude 17.4°N and longitude 127.7°E which put it about 330 miles (535 km) east of Luzon. Maliksi was moving toward the north at 4 m.p.h. (6 km/h). 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). The minimum surface pressure was 996 mb.
The Japan Meteorological Agency designated an area of low pressure east of Luzon as Tropical Storm Maliksi late on Thursday. There was a large counterclockwise circulation east of Luzon, but there were few thunderstorms near the center of the circulation. Most of the thunderstorms were occurring in three bands in the outer portions of the circulation. One band was located well to the west of the center of circulation, a second band was located well to the north of the center and the third band was located well to the east of the center. The winds to tropical storm force were occurring in those bands.
Tropical Storm Maliksi will move through an environment favorable for intensification during the next 24 to 48 hours. Maliksi will move over water where the Sea Surface Temperature is near 30°C. Maliksi will move underneath an upper level ridge where the winds are weak and there will be little vertical wind shear. The large circulation will be the primary factor inhibiting intensification in the short term. Maliksi will intensify slowly until thunderstorms develop near the center of circulation and the strongest winds occur closer to the center.
Tropical Storm Maliksi will move around the western end of a subtropical ridge. The ridge will steer Maliksi slowly toward the north. When Tropical Storm Maliksi moves farther to the north westerly winds will begin to steer it toward the northeast. On its anticipated track Tropical Storm Maliksi will remain east of Luzon. The circulation of Maliksi is so large that rainbands on the western side of the circulation could affect the northern Philippines.
Elsewhere over the western North Pacific Ocean, Tropical Storm Ewiniar brought heavy rain to parts of South China. Ewiniar made landfall on the coast of China near Yangjiang on Thursday. At 8:00 p.m. EDT on Thursday the center of Tropical Storm Ewiniar was located at latitude 22.6°N and longitude 112.1°E which put it about 50 miles (80 km) northeast of Yangjiang, China. Ewiniar was moving toward the north at 9 m.p.h. (15 km/h). 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). The minimum surface pressure was 998 mb.
The center of Tropical Storm Ewiniar was moving farther inland over South China. The winds to tropical storm force were occurring in rainbands that were still over the South China Sea. Ewiniar was dropping heavy rain over parts of western Guangdong province and over southern Zizhiqu province. The heavy rain could cause flooding in those areas.
