Tropical Storm Mawar Brings Wind and Rain to Okinawa

Tropical Storm Mawar brought wind and rain to Okinawa on Thursday. At 11:00 a.m. EDT on Thursday the center of Tropical Storm Mawar was located at latitude 26.1°N and longitude 127.5°E which put it about 65 miles (105 km) southwest of Okinawa. Mawar was moving toward the northeast at 13 m.p.h. (20 km/h). The maximum sustained wind speed was 60 m.p.h. (95 km/h) and there were wind gusts to 75 m.p.h. (120 km/h). The minimum surface pressure was 972 mb.

Former Typhoon Mawar weakened to a tropical storm as it moved closer to Okinawa on Thursday. Even though Mawar was a tropical storm, it still produced gusty winds and rain in Okinawa. A weather station in Naha measured a sustained wind speed of 41 m.p.h. (66 km/h). The distribution of thunderstorms was asymmetrical in Tropical Storm Mawar. Most of the thunderstorms were occurring in bands east and south of the center of Mawar. Bands in the northern and western parts of Tropical Storm Mawar consisted primarily of showers and lower clouds. Winds to tropical storm force extended out 250 miles (400 km) from the center of Mawar’s circulation.

Tropical Storm Mawar will move through an environment that will be unfavorable for intensification during the next 48 hours. Mawar will move over water where the Sea Surface Temperatures are near 25˚C. It will move under the eastern part of an upper level trough that is west of Japan. The upper level trough will produce southwesterly winds that will blow toward the top of Mawar’s circulation. Those winds will cause more vertical wind shear. Tropical Storm Mawar will also pull drier air from Asia into the western part of its circulation. More vertical wind shear and drier air will cause Tropical Storm Mawar to gradually weaken.

The upper level trough west of Japan will steer Tropical Storm Mawar toward the northeast during the next 48 hours. On its anticipated track the center of Mawar will pass near Okinawa during the next few hours. Weather conditions in Okinawa will start to improve when Tropical Storm Mawar moves away later today. Mawar will pass south of Honshu after it moves away from Okinawa. Tropical Storm Mawar could pass south of Tokyo in less than 48 hours.

Tropical Storm Mawar Develops South-southeast of Guam

Tropical Storm Mawar developed over the Western North Pacific Ocean south-southeast of Guam on Saturday. At 5:00 p.m. EDT on Saturday the center of Tropical Storm Mawar was located at latitude 6.4°N and longitude 149.1°E which put it about 595 miles (960 km) south-southeast of Guam. Mawar was moving toward the north-northwest at 5 m.p.h. (8 km/h). The maximum sustained wind speed was 50 m.p.h. (80 km/h) and there were wind gusts to 65 m.p.h. (105 km/h). The minimum surface pressure was 993 mb.

Typhoon Watches were in effect for Guam, Rota, Tinian and Saipan.

Former Tropical Depression 02W strengthened on Saturday and the Japan Meteorological Agency designated the system as Tropical Storm Mawar. The circulation around Tropical Storm Mawar was organizing quickly. The inner end of a rainband wrapped around the western and southern sides of the center of Mawar’s circulation. Other bands of showers and thunderstorms were revolving around the center. Storms near the center of circulation generated upper level divergence that pumped mass away from the tropical storm. Winds to tropical storm force extended out 65 miles (105 km) from the center of Tropical Storm Mawar.

Tropical Storm Mawar will move through an environment favorable for intensification during the next 48 hours. Mawar will move over water where the Sea Surface Temperatures are near 28˚C. It will move under the western end of the axis of an upper level ridge over the Equatorial Pacific Ocean. The upper level winds are weak near the axis of the ridge and there will be little vertical wind shear. Tropical Storm Mawar will intensify during the next 48 hours. Mawar could intensify rapidly after an inner core with an eye and an eyewall form. Tropical Storm Mawar is likely to strengthen to a typhoon within 36 hours.

Tropical Storm Mawar will move around the western end of a high pressure system over the Western North Pacific Ocean. The high pressure system will steer Mawar toward the north-northwest during the next 48 hours. On its anticipated track, Tropical Storm Mawar will affect Pulawat during the next 24 hours. Mawar will bring gusty winds and locally heavy rain to Pulawat. Tropical Storm Mawar will approach the Marianas in 72 hours. Mawar will be a typhoon when it approaches the Marianas, which is why Typhoon Watches were issued for Guam, Rota, Tinian and Saipan.

Tropical Storm Mawar Nears Landfall in China

Tropical Storm Mawar moved closer to a landfall in China on Saturday.  At 11:00 p.m. EDT on Saturday the center of Tropical Storm Mawar was located at latitude 22.2°N and longitude 116.4°E which put it about 150 miles (240 km) east of Hong Kong.  Mawar was moving toward the west-northwest at 5 m.p.h. (8 km/h).  The maximum sustained wind speed was 55 m.p.h. (90 km/h) and there were wind gusts to 70 m.p.h. (110 km/h).  The minimum surface pressure was 989 mb.

The circulation of Tropical Storm Mawar is very asymmetrical.  Most of the thunderstorms are located south of the center of circulation.  A primary rainband is just south of the center of circulation and there are several other bands farther south of the center.  Recent visible satellite images suggest that the eastern end of the primary rainband could be trying to wrap around the center.  Thunderstorms in the primary rainband were generating some upper level divergence which was pumping mass away to the southwest of the tropical storm.

Tropical Storm Mawar will move through an environment that is somewhat favorable for intensification during the next 12 to 18 hours.  Mawar will move over water where the Sea Surface Temperature is near 29°C.  An upper level ridge centered over China is producing northeasterly winds which are blowing toward the top of the circulation.  Those winds are generating moderate vertical wind shear.  Those winds may also be the reason for the asymmetrical distribution of thunderstorms.  Mawar could intensify before it makes landfall in China.

Tropical Storm Mawar is being steered slowly toward the west-northwest by a ridge near Japan.  That general motion is expected to continue for the next several days.  On its anticipated track Tropical Storm Mawar will make landfall in China east of Hong Kong in 12 to 18 hours.  Mawar will bring gusty winds and locally heavy rain to parts of Guangdong province.  The rain could contribute to flooding in some locations.  Mawar is likely to weaken steadily after it makes landfall.
