Tropical Storm Maliksi Forms Southwest of Hong Kong

Tropical Storm Maliksi formed over the South China Sea southwest of Hong Kong on Friday. At 11:00 a.m. EDT on Friday the center of Tropical Storm Maliksi was located at latitude 21.4°N and longitude 111.6°E which put it about 185 miles (300 km) west-southwest of Hong Kong. Maliksi was moving toward the north-northwest at 8 m.p.h. (13 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.

A low pressure system over the South China Sea southwest of Hong Kong strengthened on Friday and the Japan Meteorological Agency designated the system as Tropical Storm Maliksi. The distribution of thunderstorms in Tropical Storm Maliksi was asymmetrical. Thunderstorms were occurring in bands in the southern half of Maliksi’s circulation. Bands in the northern half of the circulation consisted primarily of showers and lower clouds. Storms near the center of circulation generated upper level divergence that pumped mass away to the south of the tropical storm.

The distribution of wind speeds around Tropical Storm Maliksi was also asymmetrical. Winds to tropical storm force extended out 120 miles (195 km) in the southeastern part of Maliksi’s circulation. Winds to tropical storm force only extended out 60 miles (95 km) in the northwestern side of Maliksi.

Tropical Storm Maliksi will move through an environment somewhat favorable for intensification during the next few hours. Maliksi will move over water where the Sea Surface Temperatures are near 29°C. It will move under the eastern part of an upper level ridge over China. The ridge will produce northerly winds that will blow toward the top of Maliksi’s circulation. Those winds will also cause moderate vertical wind shear. The wind shear will inhibit intensification. Tropical Storm Maliksi could intensify a little during the next few hours.

Tropical Storm Maliksi will move around the western side of a high pressure system over the Western North Pacific Ocean. The high pressure will steer Maliksi toward the north during the next 24 hours. On its anticipated track, Tropical Storm Maliksi will make landfall in southern China in a few hours. Maliksi will drop heavy rain over parts of southern China. Heavy rain could cause floods in some locations.

Tropical Storm Ewiniar Weakens South of Japan

Tropical Storm Ewiniar weakened south of Japan on Thursday. At 11:00 a.m. EDT on Thursday the center of Tropical Storm Ewiniar was located at latitude 30.8°N and longitude 137.7°E which put it about 400 miles (645 km) south-southwest of Tokyo, Japan. Ewiniar was moving toward the northeast at 17 m.p.h. (28 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 995 mb.

Strong vertical wind shear and cooler Sea Surface Temperatures caused Tropical Storm Ewiniar to weaken south of Japan on Thursday. No thunderstorms were occurring in Tropical Storm Ewiniar. Bands revolving around the center of Ewiniar’s circulation consisted primarily of showers and lower clouds. Winds to tropical storm force extended out 90 miles (145 km) from the center of Ewiniar.

Tropical Storm Ewiniar will move through an environment that will be unfavorable for intensification during the next 24 hours. Ewiniar will move over water where the Sea Surface Temperatures are near 24°C. An upper level trough northwest of Japan will produce strong westerly winds that will blow across the top of Ewiniar’s circulation. Those winds will cause strong vertical wind shear. The cooler water and strong vertical wind shear will cause Tropical Storm Ewiniar to continue to weaken during the next 24 hours.

Tropical Storm Ewiniar will move around the northern side of a high pressure system over the Western North Pacific Ocean. The high pressure system and the upper level trough northwest of Japan will steer Ewiniar toward the northeast during the next 24 hours. On its anticipated track, Tropical Storm Ewiniar will remain south of Japan. Ewiniar will pass south of Tokyo in 12 hours.

Ewiniar Weakens to a Tropical Storm

Former Typhoon Ewiniar weakened to a tropical storm south of Japan on Wednesday. At 11:00 a.m. EDT on Wednesday the center of Tropical Storm Ewiniar was located at latitude 26.9°N and longitude 133.5°E which put it about 120 miles (195 km) northeast of Minamidaitojima, Japan. Ewiniar was moving toward the northeast at 18 m.p.h. (30 km/h). The maximum sustained wind speed was 70 m.p.h. (110 km/h) and there were wind gusts to 85 m.p.h. (135 km/h). The minimum surface pressure was 981 mb.

After bringing strong winds and heavy rain to Minamidaitojima, former Typhoon Ewiniar weakened to a tropical storm on Wednesday. An upper level trough northwest of Japan was producing strong southwesterly winds that were blowing toward the top of Ewiniar’s circulation. Those winds were causing strong vertical wind shear. The wind shear caused former Typhoon Ewiniar to weaken.

The strong vertical wind shear was also affecting the structure of Tropical Storm Ewiniar. The strong upper level southwesterly winds were causing the upper part of Ewinar’s circulation to tilt toward the northeast. Thunderstorms were still occurring in bands in the northern and eastern parts of Tropical Storm Ewiniar. Bands in the southern and western parts of Ewiniar consisted primarily of showers and lower clouds.

The circulation around Typhoon Ewiniar was still small. Winds to tropical storm force extended out 100 miles (160 km) from the center of circulation.

Tropical Storm Ewiniar will move through an environment that will be unfavorable for intensification during the next 24 hours. Ewiniar will move over water where the Sea Surface Temperatures are near 25°C. The upper level trough northwest of Japan will continue to cause strong vertical wind shear. The cooler water and strong vertical wind shear will cause Tropical Storm Ewiniar to weaken during the next 24 hours. If the upper level winds get stronger, they could blow the top off of Ewiniar’s circulation. The cooler water and strong vertical wind shear will also cause Tropical Storm Ewiniar to begin to make a transition to an extratropical cyclone.

Tropical Storm Ewiniar will move around the northern side of a high pressure system over the Western North Pacific Ocean. The high pressure system and the upper level trough northwest of Japan will steer Ewiniar toward the northeast during the next 24 hours. On its anticipated track, Tropical Storm Ewiniar will remain south of Japan.

Typhoon Ewiniar Passes South of Okinawa

Typhoon Ewiniar passed south of Okinawa on Tuesday. At 11:00 a.m. EDT on Tuesday the center of Typhoon Ewiniar was located at latitude 22.1°N and longitude 128.6°E which put it about 350 miles (565 km) south of Okinawa. Ewiniar was moving toward the northeast at 22 m.p.h. (35 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 980 mb.

Typhoon Ewiniar was weakening as it passed south of Okinawa on Tuesday. An upper level trough west of Japan was producing southwesterly winds that were blowing toward the top of Ewiniar’s circulation. Those winds were causing moderate vertical wind shear. The wind shear was causing Typhoon Ewiniar to weaken.

The vertical wind shear was also affecting the structure of Typhoon Ewiniar. An eye was no longer visible at the center of Ewiniar’s circulation. Thunderstorms were occurring in a band that wrapped around the southern and eastern sides of the center of circulation. Bands in the other parts of Typhoon Ewiniar consisted primarily of showers and lower clouds. Storms near the center of Ewiniar still generated upper level divergence that pumped mass away from the typhoon.

The circulation around Typhoon Ewiniar was still small. Winds to typhoon force extended out 25 miles (40 km) from the center of Ewiniar’s circulation. Winds to tropical storm force extended out 90 miles (145 km) from the center of circulation.

Typhoon Ewiniar will move through an environment that will be unfavorable for intensification during the next 24 hours. Ewiniar will move over water where the Sea Surface Temperatures are near 28°C. The upper level trough west of Japan will continue to cause moderate vertical wind shear. Since the circulation around Ewiniar is small, the wind shear will cause Typhoon Ewiniar to weaken during the next 24 hours.

Typhoon Ewiniar will move around the northern side of a high pressure system over the Western North Pacific Ocean. The high pressure system and the upper level trough west coast of Japan will steer Ewiniar toward the northeast during the next 24 hours. On its anticipated track, Typhoon Ewiniar will pass near Minamidaitojoma in 12 to 18 hours. Ewiniar will bring strong winds and locally heavy rain to Minamidaitojima.

Typhoon Ewiniar Moves Away From Luzon

Typhoon Ewiniar moved away from Luzon on Monday. At 11:00 a.m. EDT on Monday the center of Typhoon Ewiniar was located at latitude 17.4°N and longitude 124.3°E which put it about 185 miles (300 km) east of Tuguegarao, Philippines. Ewiniar was moving toward the northeast at 9 m.p.h. (15 km/h). The maximum sustained wind speed was 100 m.p.h. (160 km/h) and there were wind gusts to 120 m.p.h. (195 km/h). The minimum surface pressure was 966 mb.

After intensifying rapidly on Sunday, Typhoon Ewiniar showed signs of weakening on Monday. A small eye with a diameter of 5 miles (8 km) was still present at the center of Ewiniar’s circulation. However, there were breaks in the ring of thunderstorms surrounding the eye. Storms near the center of Ewiniar still were generating upper level divergence that was pumping mass away from the typhoon. Bands of showers and thunderstorms were revolving around the center of Typhoon Ewiniar.

The circulation around Typhoon Ewiniar was small. Winds to typhoon force extended out 20 miles (30 km) from the center of Ewiniar’s circulation. Winds to tropical storm force extended out 75 miles (120 km) from the center of circulation.

Typhoon Ewiniar will move through an environment that will become less favorable for intensification during the next 24 hours. Ewiniar will move over water where the Sea Surface Temperatures are near 30°C. An upper level trough near the east coast of China will produce southwesterly winds that will blow toward the top of Ewiniar’s circulation. Those winds will cause the vertical wind shear to increase. Since the circulation around Ewiniar is small, an increase in wind shear will have a larger effect on the typhoon. Typhoon Ewiniar is likely to weaken during the next 24 hours when the vertical wind shear increases.

Typhoon Ewiniar will move around the northwestern part of a high pressure system over the Western North Pacific Ocean. The high pressure system and the upper level trough near the east coast of China will steer Ewiniar toward the northeast during the next 24 hours. On its anticipated track, Typhoon Ewiniar will continue to move farther away from Luzon. Ewiniar will pass southeast of the Ryukyu Islands during the next few days.

Elsewhere, Tropical Cyclone Remal continued to drop heavy rain on Bangladesh. There were reports that Remal caused fatalities in Bangladesh. At 5:00 a.m. EDT on Monday the center of Tropical Cyclone Remal was located at latitude 23.1°N and longitude 89.2°E which put it about 85 miles (140 km) southwest of Dhaka, Bangladesh. Remal was moving toward the north-northeast at 5 m.p.h. (8 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 979 mb.

Tropical Cyclone Remal Brings Wind and Rain to West Bengal and Bangladesh

Tropical Cyclone Remal brought wind and rain to West Bengal and Bangladesh on Sunday. At 5:00 p.m. EDT on Sunday the center of Tropical Cyclone Remal was located at latitude 22.0°N and longitude 88.5°E which put it about 65 miles (105 km) south of Kolkata, India. Remal was moving toward the north at 9 m.p.h. (15 km/h). The maximum sustained wind speed was 65 m.p.h. (105 km/h) and there were wind gusts to 80 m.p.h. (130 km/h). The minimum surface pressure was 978 mb.

The center of Tropical Cyclone Remal made landfall on the coast of West Bengal south of Kolkata on Sunday. The circulation around Remal was large at the time of landfall. Winds to tropical storm force extended out 165 miles (265 km) from the center of Remal’s circulation. A weather station at Mongla, Bangladesh reported a sustained wind speed of 47 m.p.h. (76 km/h).

Tropical Cyclone Remal was moving along with the leading edge of a surge of humid air moving north in the monsoonal flow over the Bay of Bengal. The monsoonal flow will steer Remal toward the northeast during the next 24 hours. On its anticipated track Tropical Cyclone Remal will move inland across Bangladesh.

Tropical Cyclone Remal will weaken gradually as it moves farther inland. Remal will continue to bring strong winds and locally heavy rain to Bangladesh and adjacent parts West Bengal. Heavy rain is likely to cause floods in some locations. Remal could also cause a storm surge of up to 7 feet (2 meters) along the coast of Bangladesh. Weather conditions should start to improve gradually on Monday when Tropical Cyclone Remal moves farther inland and weakens.

Ewiniar Rapidly Intensifies to a Typhoon East of Luzon

Former Tropical Storm Ewiniar rapidly intensified to a typhoon east of Luzon on Sunday. At 11:00 a.m. EDT on Sunday the center of Typhoon Ewiniar was located at latitude 15.2°N and longitude 122.5°E which put it about 125 miles (200 km) east-northeast of Manila, Philippines. Ewiniar was moving toward the northeast at 7 m.p.h. (11 km/h). The maximum sustained wind speed was 90 m.p.h. (145 km/h) and there were wind gusts to 115 m.p.h. (185 km/h). The minimum surface pressure was 966 mb.

Former Tropical Storm Ewiniar rapidly intensified to a typhoon after it moved east of Luzon on Sunday. A very small eye with a diameter of 5 miles (8 km) formed at the center of Typhoon Ewiniar. The eye was surrounded by a ring of thunderstorms and the strongest winds were occurring in that ring of storms. Bands of showers and thunderstorms revolved around the center of Ewiniar’s circulation. Storms near the center generated upper level divergence that pumped mass away from the typhoon. The removal of mass caused the surface pressure to decrease rapidly.

The circulation around Typhoon Ewiniar was small. Winds to typhoon force extended out 20 miles (30 km) from the center of Ewiniar’s circulation. Winds to tropical storm force extended out 60 miles (95 km) from the center of circulation.

Typhoon Ewiniar will move through an environment that will be very favorable for intensification during the next 24 hours. Ewiniar will move over water where the Sea Surface Temperatures are near 31°C. It will move under the western part of an upper level ridge over the Western North Pacific Ocean. The upper level ridge will produce southwesterly winds that will blow toward the top of Ewiniar’s circulation. The winds in the lower levels of the atmosphere will also blow from the southwest and there will be little vertical wind shear. Typhoon Ewiniar is likely to intensify during the next 24 hours. Ewiniar could continue to intensify rapidly. If the inner end of a rainband wraps around the existing eye and eyewall, then an eyewall replacement cycle could interrupt the intensification.

Typhoon Ewiniar will move around the western end of a high pressure system that is east of the Philippines. The high pressure system will steer Ewiniar toward the northeast during the next 24 hours. On its anticipated track, Typhoon Ewiniar will move farther away from Luzon during the next 24 hours. Ewiniar will pass southeast of the Ryukyu Islands during the early part of next week.

Typhoon Ewiniar will continue to produce strong winds and locally heavy rain in Luzon until it moves farther to the northeast. Heavy rain is likely to cause flash floods in some locations.

Tropical Cyclone Remal Approaches Bangladesh

Tropical Cyclone Remal was approaching the coast of Bangladesh and West Bengal on Sunday morning. At 5:00 a.m. EDT on Sunday the center of Tropical Cyclone Remal was located at latitude 20.7°N and longitude 88.9°E which put it about 155 miles (250 km) south-southeast of Kolkata, India.

The minimum surface pressure was 985 mb.

Tropical Cyclone Remal was strengthening as it approached the coast of Bangladesh and West Bengal on Sunday morning. Even though Remal was getting stronger, the distribution of thunderstorms was asymmetrical. Most of the thunderstorms were occurring in bands in the southern half of Remal’s circulation. Bands in the northern part of Tropical Cyclone Remal consisted primarily of showers and lower clouds. Storms near the center of Remal’s circulation generated upper level divergence that pumped mass away from the tropical cyclone. The removal of mass caused the surface pressure to decrease.

The circulation around Tropical Cyclone Remal was large. Winds to tropical storm force extended out 190 miles (305 km) from the center of Remal’s circulation.

Tropical Cyclone Remal will move through an environment favorable for intensification during the next 12 hours. Remal will move over water where the Sea Surface Temperatures are near 31°C. It will move under the axis of an upper level ridge over South Asia and the Bay of Bengal. The winds are weak near the axis off the ridge and there will be little vertical wind shear. Tropical Cyclone Remal is likely to intensify during the next 12 hours. The large circulation around Remal could cause intensification to occur slowly.

Tropical Cyclone Remal formed along the leading edge of a surge of humid air moving north in the monsoonal flow over the Bay of Bengal. The monsoonal flow will continue to steer Remal north during the next 12 hours. On its anticipated track Tropical Cyclone Remal will reach the northern coast of the Bay of Bengal in 12 hours. The center of Remal is likely to make landfall near the western border between India and Bangladesh.

Tropical Cyclone Remal will bring strong winds and locally heavy rain to Bangladesh and adjacent parts West Bengal. Heavy rain is likely to cause floods in some locations. Remal could also cause a storm surge of up to 7 feet (2 meters) along the coast of Bangladesh.

Tropical Storm Ewiniar Strengthens Near Manila

Tropical Storm Ewiniar strengthened near Manila on Saturday night.

The circulation around Tropical Storm Ewiniar was very symmetrical. Thunderstorms were occurring near the center of Ewiniar’s circulation. Bands of showers and thunderstorms were revolving around the center of circulation. Storms near the center of Ewiniar generated upper level divergence that pumped mass away from the tropical storm. The removal of mass caused the surface pressure to decrease.

The circulation around Tropical Storm Ewiniar was relatively small. Winds to tropical storm force extended out 60 miles (95 km) from the center of Ewiniar’s circulation.

Tropical Storm Ewiniar will move through an environment that will be mostly favorable for intensification during the next 24 hours. Ewiniar will move over water where the Sea Surface Temperatures are near 31°C. It will move under the western part of an upper level ridge over the Western North Pacific Ocean. The upper level ridge will produce southerly winds that will blow toward the top of Ewiniar’s circulation. Those winds will cause some vertical wind shear, but the shear will not be strong enough to prevent intensification. Even though part of the circulation around Tropical Storm Ewiniar will pass over Luzon, Ewiniar is likely to intensify during the next 24 hours.

Tropical Storm Ewiniar will move around the western end of a high pressure system that is east of the Philippines. The high pressure system will steer Ewiniar toward the north during the next 24 hours. On its anticipated track, Tropical Storm Ewiniar will move along the east coast of Luzon during the next 24 hours. Ewiniar will start to move toward the northeast on Monday after is moves around the western end of the high pressure system.
