Tropical Storm Bailu Brings Wind and Rain to Taiwan

Tropical Storm Bailu brought wind and rain to Taiwan early on Saturday.  At 5:00 a.m. EDT on Saturday the center of Tropical Storm Bailu was located at latitude 22.6°N and longitude 120.2°E which put it about 50 miles (80 km) northwest of Hengchun, Taiwan.  Bailu was moving toward the northwest at 15 m.p.h. (24 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 986 mb.

The broad center of Tropical Storm Bailu moved across southern Taiwan early on Saturday.  Bailu produced winds to tropical storm force over parts of Taiwan, but its greater effect was heavy rain.  Since Tropical Storm Bailu passed near the southern end of Taiwan, its counterclockwise rotation produced easterly winds over much of Taiwan.  Those winds pushed air up the mountains, which enhanced rising motion and caused heavy rain to fall over eastern Taiwan.  Estimates of rainfall from radars indicated that up to one foot (300 mm) of rain could have fallen over southeastern Taiwan.  That much rain is likely to have caused flash floods in some locations.

Tropical Storm Bailu will continue to move southwest of a subtropical ridge over the Western North Pacific Ocean.  The ridge will continue to steer Bailu toward the northwest.  On its anticipated track the center of Tropical Storm Bailu will make landfall on the east coast of China between Xiamen and Shantou in about 12 hours.  Bailu will bring gusty winds and locally heavy rain to parts of eastern China.  Heavy rain could also produce flash floods in some locations.

Tropical Storm Bailu on Track Toward Taiwan

Tropical Storm Bailu remained on a track toward Taiwan on Thursday night.  At 11:00 p.m. EDT on Thursday the center of Tropical Storm Bailu was located at latitude 19.0°N and longitude 125.6°E which put it about 385 miles (615 km) east-southeast of Hengchun, Taiwan.  Bailu was moving toward the northwest at 15 m.p.h. (24 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 990 mb.

The circulation around Tropical Storm Bailu was large.  Winds to tropical storm force extended out about 170 miles (280 km) from the center of circulation.  Many of the stronger thunderstorms in Bailu were occurring in bands in the southern half of the circulation.  Bands in the northern half of the circulation consisted primarily of showers and lower clouds.  Tropical Storm Bailu was moving south of an upper level ridge.  The ridge was causing sinking motion to the north of Bailu which appeared to be limiting the development of taller thunderstorms in the northern half of the circulation.

Aside from the sinking motion north of Tropical Storm Bailu, it will move through an environment favorable for intensification.  Bailu will move over water where the Sea Surface Temperature is near 29°C.  It will move through a region where the upper level winds are not too strong and there will not be a lot of vertical wind shear.  Tropical Storm Bailu could intensify on Friday if more thunderstorms develop around the center of circulation.  There is a chance that Bailu could strengthen into a typhoon.

Tropical Storm Bailu will move around the southwestern part of a subtropical ridge over the Western North Pacific Ocean.  The ridge will steer Bailu toward the northwest.  On its anticipated track Tropical Storm Bailu could approach southern Taiwan in about 24 hours.  Bailu could be a typhoon by that time.  It will bring gusty winds and locally heavy rain to Taiwan.  The locally heavy rain could cause flash floods in some locations.

Tropical Storm Bailu Forms East of Luzon

Tropical Storm Bailu formed east of Luzon on Wednesday.  At 5:00 a.m. EDT on Wednesday the center of Tropical Storm Bailu was located at latitude 15.4°N and longitude 131.6°E which put it about 930 miles (1500 km) southeast of Taipei, Taiwan.  Bailu was moving toward the 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 east of northern Luzon strengthened on Wednesday and the Japan Meteorological Agency designated the system as Tropical Storm Bailu.  The circulation around Bailu was gradually exhibiting greater organization.  Bands of showers and thunderstorms were forming and the bands were starting to revolve around the center of the tropical storm.  There were more thunderstorms in the bands on the western side of Tropical Storm Bailu.  Storms near the center of circulation were beginning to generate upper level divergence which was pumping mass away from Bailu.

Tropical Storm Bailu will move through an environment favorable for intensification during the next two to three days.  Bailu will move over water where the Sea Surface Temperature is near 28.5°C.  It will move southeast of an upper level ridge that extends from eastern Asia over the Western North Pacific Ocean.  The ridge will produce northeasterly winds which will blow toward the top of the circulation.  Those winds will cause some vertical wind shear, but the shear will not be strong enough to prevent intensification.  Tropical Storm Bailu will intensify during the next several days and it could strengthen into a typhoon.

Tropical Storm Bailu will move south of a subtropical ridge over the Western North Pacific Ocean.  The ridge will steer Bailu in a northwesterly direction.  On its anticipated track Tropical Storm Bailu could approach Taiwan in about 72 hours.  Bailu could be a typhoon by that time.  Bands on the western side of Tropical Storm Bailu could drop locally heavy rain over parts of northern Luzon.  Flash floods could occur in some locations.

Typhoon Lekima Moves Through Southern Ryukyu Islands

Powerful Typhoon Lekima moved through the southern Ryukyu Islands on Thursday.  At 5:00 p.m. EDT on Thursday the center of Typhoon Lekima was located at latitude 25.8°N and longitude 124.2°E which put it about 405 miles (655 km) south-southeast of Shanghai, China.  Lekima was moving toward the north-northwest at 13 m.p.h. (20 km/h).  The maximum sustained wind speed was 140 m.p.h. (225 km/h) and there were wind gusts to 165 m.p.h. (270 km/h).  The minimum surface pressure was 935 mb.

An inner rainband wrapped around the original eye and eyewall of Typhoon Lekima and a larger outer eye formed around the original eye.  The inner eye remained intact and the strongest winds were occurring in a small ring of thunderstorms around the inner eye.  The diameter of the outer eye was about 60 miles (95 km).  Additional bands of showers and thunderstorms were revolving around the two concentric eyewalls.

The formation of two concentric eyewalls increased the size of the circulation around Typhoon Lekima.  Winds to typhoon force extended out about 80 miles (130 km) from the center of circulation.  Winds to tropical storm force extended out about 275 miles (445 km) from the center.  The Hurricane Intensity Index (HII) for Typhoon Lekima was 28.3.  The Hurricane Size Index (HSI) was 28.1 and the Hurricane Wind Intensity Size Index (HWISI) was 56.4.  Those indices indicated that Typhoon Lekima was capable of causing widespread significant damage.

The inner eye of Typhoon Lekima wobbled between Ishigakijima and Miyakojima on Thursday.  The inner eyewall appeared to pass over Taramajima and Minnajima.  No reports were available from a weather station on Taramajima.  Stations on Ishigakijima and Miyakojima reports winds to tropical storm force, but the strong inner eye passed between those two islands.

The formation of the larger outer eye probably indicates that an eyewall replacement cycle will occur.  Typhoon Lekima will weaken when the inner eyewall dissipates.  However, the circulation will remain large.  Typhoon Lekima will be in an environment favorable for strong typhoons during the next 24 hours.  Lekima will move over water where the Sea Surface Temperature is near 28.5°C.  It will move through a region where the upper level winds are not strong and there will not be a lot of vertical wind shear.  Typhoon Lekima will weaken because of an eyewall replacement cycle, but it will remain a large, powerful typhoon.

Typhoon Lekima will move around the western end of a subtropical ridge over the Western North Pacific Ocean.  The ridge will steer Lekima toward the north-northwest during the next several days.  On its anticipated track Typhoon Lekima could approach the coast of China south of Shanghai in about 24 hours.  It is likely to be a large typhoon at that time.

Elsewhere around the Western North Pacific Ocean, Typhoon Krosa was nearly stationary south of Iwo To on Thursday.  At 5:00 p.m. EDT on Thursday the center of Typhoon Krosa was located at latitude 22.1°N and longitude 141.0°E which put it about 195 miles (315 km) south of Iwo To.  Krosa was nearly stationary.  The maximum sustained wind speed was 110 m.p.h. (180 km/h) and there were wind gusts to 130 m.p.h. (210 km/h).  The minimum surface pressure was 950 mb.

The circulation around Typhoon Krosa was also large.  Winds to typhoon force extended out about 75 miles (120 km) from the center of circulation.  Winds to tropical storm force extended out about 250 miles (405 km) from the center.  The Hurricane Intensity Index (HII) for Typhoon Krosa was 19.2.  The Hurricane Size Index (HSI) was 28.4 and the Hurricane Wind Intensity Size Index (HWISI) was 47.6.

Typhoon Krosa is forecast to move slowly north toward Iwo To on Friday.  On its anticipated track Krosa could approach Iwo To in about 36 hours.  It will be a large typhoon capable of causing serious damage at that time.

Typhoons Lekima and Krosa Threaten Japanese Islands

Typhoons Lekima and Krosa threatened Japanese islands on Wednesday.  Typhoon Lekima posed a serious threat to the southern Ryukyu Islands and Typhoon Krosa was headed for Iwo To.  At 5:00 p.m. EDT on Wednesday the center of Typhoon Lekima was located at latitude 22.4°N and longitude 126.0°E which put it about 190 miles (305 km) southeast of Ishigaki, Japan.  Lekmia was moving toward the northwest at 8 m.p.h. (13 km/h).  The maximum sustained wind speed was 125 m.p.h. (200 km/h) and there were wind gusts to 155 m.p.h. (250 km/h).  The minimum surface pressure was 925 mb.

Typhoon Lekima rapidly intensified into the equivalent of a major hurricane on Wednesday.  A small distinct eye was at the center of circulation.  The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms.  Several bands of showers and thunderstorms were revolving around the core of the circulation.  Storms near the core were generating strong upper level divergence which was pumping mass away from the typhoon in all directions.

Typhoon Lekima had a large circulation.  Winds to typhoon force extended out about 60 miles (95 km) from the center of circulation.  Winds to tropical storm force extended out about 210 miles (335 km) from the center.  The Hurricane Intensity Index (HII) for Typhoon Lekima was 23.6.  The Hurricane Size Index (HSI) was 21.6 and the Hurricane Wind Intensity Size Index (HWISI) was 44.7.   Those indices indicated that Typhoon Lekima was capable of causing widespread major damage.

Typhoon Lekima will move through an environment favorable for intensification during the next 24 hours.  Lekima will move over water where the Sea Surface Temperature is near 30°C.  It will move through a region where the upper level winds are weak and there will not be a lot of vertical wind shear.  Typhoon Lekima could intensify further during the next day or so.  It is possible that a rainband could wrap around the existing eye and eyewall.  If a rainband wraps around the core of Lekima then an eyewall replacement cycle could cause weakening.

Typhoon Lekima will move around the western end of a subtropical ridge over the Western North Pacific Ocean.  The ridge will steer Lekima toward the northwest on Thursday.  On its anticipated track Typhoon Lekima will reach Ishigaki and the southern Ryukyu Islands in less than 24 hours.  Lekima will be capable of causing major damage to the southern Ryukyu Islands.  Typhoon Lekima will move more toward the north when it moves around the end of the subtropical ridge.  The center of Lekima could be northeast of Taiwan within 36 hours.  Typhoon Lekima could reach the east coast of China in less than three days.

At 5:00 p.m. EDT on Wednesday the center of Typhoon Krosa was located at latitude 22.1°N and longitude 140.8°E which put it about 210 miles (340 km) south of Iwo To.  Krosa was moving toward the north-northwest at 5 m.p.h. (8 km/h).  The maximum sustained wind speed was 80 m.p.h. (130 km/h) and there were wind gusts to 100 m.p.h. (160 km/h).  The minimum surface pressure was 970 mb.

Former Tropical Storm Krosa strengthened into a typhoon on Wednesday.  The inner portion of a rainband wrapped around the center of circulation and an eye formed.  The inner part of the rainband closed around the eye and a circular ring of thunderstorms formed a closed eyewall.  The strongest winds were occurring in the eyewall.  Several bands of showers and thunderstorms were revolving around the core of Typhoon Krosa.  Storms near the center were pumping mass away to the east of the typhoon.

The circulation around Typhoon Krosa was also large.  Winds to typhoon force extended out about 60 miles (95 km) from the center of circulation.  Winds to tropical storm force extended out about 225 miles (360 km) from the center.  The Hurricane Intensity Index for Typhoon Krosa was 11.5.  The Hurricane Size Index was 22.5 and the Hurricane Wind Intensity Size Index was 34.0.

Typhoon Krosa will move through an environment mostly favorable for intensification.  Krosa will move over water where the Sea Surface Temperature is near 29°C.  Upper level divergence from Typhoon Lekima which is to the west of Typhoon Krosa could cause some vertical wind shear.  The wind shear will not be great enough to prevent intensification, but it could slow the rate at which Typhoon Krosa strengthens.

Typhoon Krose will move into a region where the steering winds are weaker.  Typhoon Krosa is forecast to move slowly toward the north during the next two or three days.  On its anticipated track the center of Typhoon Krosa could be near Iwo To in about 48 hours.

Tropical Storm Francisco Drops Heavy Rain on South Korea

Tropical Storm Francisco dropped heavy rain on parts of South Korea on Tuesday.  At 5:00 p.m. EDT on Tuesday the center of Tropical Storm Francisco was located at latitude 37.4°N and longitude 129.4°E which put it about 25 miles (40 km) southwest of Tonghae, South Korea.  Francisco was moving toward the north at 14 m.p.h. (22 km/h).  The maximum sustained wind speed was 45 m.p.h. (75 km/h) and there were wind gusts to 60 m.p.h. (95 km/h).  The minimum surface pressure was 999 mb.

After moving across Kyushu on Monday night, the center of Tropical Storm Francisco crossed the Korea Strait and moved northward over eastern South Korea.  The center of Francisco made landfall near Busan (Pusan), South Korea.  Bands of showers and thunderstorms in the northern half of Tropical Storm Francisco dropped heavy rain over parts of South Korea.  The rain could create the potential for flash floods in some locations.  Winds to tropical storm force were occurring in the portions of rainbands over the Sea of Japan.

Tropical Storm Francisco will soon reach a region where the westerly winds in the middle latitudes are blowing.  Those winds will turn Francisco eastward over the Sea of Japan.  Tropical Storm Francisco will move over water where the Sea Surface Temperatures are near 26°C.  However, the westerly winds in the upper levels will create strong vertical wind shear and significant intensification is not expected.  On its anticipated track, Tropical Storm Francisco could reach Hokkaido in about 48 hours.  Francisco could still be a tropical storm at that time.

Elsewhere over the Western North Pacific Ocean, Lekima strengthened into a typhoon southeast of Taiwan and Tropical Storm Krosa intensified south of Iwo To.  At 5:00 p.m. EDT on Tuesday the center of Typhoon Lekima was located at latitude 19.7°N and longitude 127.9°E which put it about 575 miles (925 km) southeast of Taipei, Taiwan.  Lekima was moving toward the northwest at 5 m.p.h. (8 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 967 mb.  Typhoon Lekima could strengthen into the equivalent of a major hurricane and it is forecast to move toward Taiwan and the southern Ryukyu Islands.

At 5:00 p.m. EDT on Tuesday the center of Tropical Storm Krosa was located at latitude 19.9°N and longitude 141.9°E which put it about 360 miles (585 km) south of Iwo To.  Krosa was moving toward the north-northwest at 10 m.p.h. (16 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 990 mb.  Tropical Storm Krosa is forecast to strengthen into a hurricane and to move toward Iwo To.

Typhoon Francisco Brings Wind and Rain to Kyushu

Typhoon Francisco brought wind and rain to Kyushu on Monday.  At 5:00 p.m. EDT on Monday the center of Typhoon Francisco was located at latitude 32.2°N and longitude 131.4°E which put it about 20 miles (35 km) north of Miyazaki, Japan.  Francisco was moving toward the west-northwest at 13 m.p.h. (20 km/h).  The maximum sustained wind speed was 85 m.p.h. (135 km/h) and there were wind gusts to 100 m.p.h. (160 km/h).  The minimum surface pressure was 969 mb.

Typhoon Francisco strengthened on Monday as it neared the coast of Kyushu.  A small eye developed at the center of circulation.  A ring of strong thunderstorms surrounded the eye and the strongest winds were occurring in that ring of storms.  Several bands of showers and thunderstorms were revolving around the core of Typhoon Francisco.  The stronger bands were primarily in the eastern half of the circulation.

The core of Typhoon Francisco made landfall on Kyushu just to the north of Miyazaki.  Typhoon Francisco will bring very heavy rain and strong gusty winds to much of Kyushu.  Francisco is forecast to turn toward the northwest and the center of circulation will move across the middle of Kyushu.  Locally heavy rain falling on steep terrain will create the potential for serious flash flooding in some locations.  Rainbands in the eastern half of Typhoon Francisco will also drop locally heavy rain over parts of western Shikoku and western Honshu.

Typhoon Francisco will weaken when it moves across Honshu, but then it will move over the Korea Strait and make another landfall in South Korea.  Francisco will bring gusty winds and locally heavy rain to parts of southern South Korea on Tuesday.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Lekima continue to meander east of Luzon.  At 11:00 a.m. EDT on Monday the center of Tropical Storm Lekima was located at latitude 18.7° and longitude 129.3°E which put it about 670 miles (1085 km) south-southeast of Taipei, Taiwan.  Lekima was moving toward the southwest at 6 m.p.h. (10 km/h).  The maximum sustained wind speed was 45 m.p.h. (75 km/h) and there were wind gusts to 60 m.p.h. (95 km/h).  The minimum surface pressure was 990 mb.

Tropical Storm Lekima Forms East of Luzon

Tropical Storm Lekima formed east of Luzon on Sunday.  More thunderstorms developed near the center of former Tropical Depression 10W and the Japan Meteorological Agency designated the system as Tropical Storm Lekima.  At 5:00 a.m. EDT on Sunday the center of Tropical Storm Lekima was located at latitude 16.8°N and longitude 131.3°E which put it about 725 miles (1170 km) south-southeast of Okinawa.  Lekima was moving toward the northwest at 6 m.p.h. (10 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 distribution of thunderstorms around Tropical Storm Lekima was asymmetrical.  Many of the stronger thunderstorms were occurring in bands west of the center of circulation.  There were fewer thunderstorms in the eastern half of the circulation.  Lekima was near the western end of an upper level ridge.  The ridge was producing easterly winds which were blowing toward the top of the circulation.  Those winds were causing moderate vertical wind shear and the wind shear was contributing to the asymmetrical distribution of thunderstorms.

Tropical Storm Lekima will move through an environment favorable for intensification during the next few days.  Lekima will move over water where the Sea Surface Temperature is near 31°C.  It will move gradually into a region where the upper level winds are weaker and the vertical wind shear will diminish.  Tropical Storm Lekima will intensify and it could strengthen into a typhoon early next week.

Tropical Storm Lekima will move around the southwestern part of a subtropical ridge over the Western North Pacific Ocean.  The ridge will steer Lekima toward the northwest.  On its anticipated track Tropical Storm Lekima could approach the southern Ryukyu Islands and Taiwan in about four days.  Lekima could be a typhoon by that time.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Francisco was speeding toward southwestern Japan.  At 5:00 a.m. EDT on Sunday the center of Tropical Storm Francisco was located at latitude 28.9°N and longitude 140.8°E which put it about 710 miles (1150 km) east-southeast of Kagoshima, Japan.  Francisco was moving toward the northwest at 19 m.p.h. (32 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 992 mb.

Tropical Storm Danas Nears Southern Ryukyu Islands

Tropical Storm Danas moved near the southern Ryukyu Islands late on Wednesday.  At 11:00 p.m. EDT on Wednesday the center of Tropical Storm Danas was located at latitude 23.9°N and longitude 124.1°E which put it about 30 miles (50 km) south of Ishigaki, Japan.  Danas was moving toward the north at 21 m.p.h. (34 km/h).  The maximum sustained wind speed was 45 m.p.h. (75 km/h) and there were wind gusts to 60 m.p.h. (95 km/h).  The minimum surface pressure was 990 mb.

The circulation around Tropical Storm Danas exhibited a little more organization on Wednesday.  More thunderstorms formed near the center of circulation and several bands of showers and thunderstorms formed in the eastern half of the circulation.  The bands north and west of the center consisted primarily of showers and lower clouds.  Storms near the center began to generate upper level divergence which pumped mass away to the northeast of the tropical storm.  Winds to tropical storm force extended out about 125 miles (200 km) from the center of circulation.

Tropical Storm Danas will move into an environment somewhat favorable for intensification.  Danas will move over water where the Sea Surface Temperature is near 30°C.  A small upper level low near Taiwan will produce southwesterly winds which blow toward the top of the circulation around Tropical Storm Danas.  Those winds were the reason why the stronger rainbands were in the eastern half of the circulation.  Those winds will cause moderate vertical wind shear, which will inhibit intensification.  However, the shear will have less of an effect since Danas will move in the same direction as the upper level winds.  Tropical Storm Danas is likely to intensify during the next 24 hours and there is a chance it could strengthen into a typhoon.

Tropical Storm Danas will move around the western end of a subtropical ridge over the western North Pacific Ocean.  The ridge will steer Danas toward the north-northeast.  On its anticipated track Tropical Storm Danas will move through the southern Ryukyu Islands during the next few hours.  Danas will bring gusty winds and locally heavy rain when it passes over those islands.  Tropical Storm Danas will move over the East China Sea toward southwestern Japan and South Korea during the next several days.

Tropical Storm Danas Forms East of Luzon

Tropical Storm Danas formed east of Luzon on Tuesday.  A distinct low level center of circulation developed in an area of low pressure east of Luzon and the Japan Meteorological Agency designated the system as Tropical Storm Danas.  At 5:00 p.m. EDT on Tuesday the center of Tropical Storm Danas was located at latitude 17.5°N and longitude 123.1°E which put it about 80 miles (130 km) east of Tuguegarao, Philippines.  Danas was moving toward the west 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 994 mb.

The distribution of thunderstorms around Tropical Storm Danas was highly asymmetrical.  There were a few thunderstorms just to the southwest of the center of circulation, but most of the thunderstorms were occurring in a band on the far western edge of the circulation around Danas.  Bands in other parts of the circulation consisted primarily of showers and lower clouds.  Tropical Storm Danas was moving around the southeastern portion of an upper level ridge over east Asia.  The ridge was producing strong easterly winds which were blowing across the top of the circulation around Danas.  The easterly winds were causing strong vertical wind shear and the wind shear was causing the asymmetric distribution of thunderstorms.  The circulation around Tropical Storm Danas was large.  Winds to tropical storm force extended out about 200 miles (320 km) from the center of circulation.

Tropical Storm Danas will move into an environment that is only marginally favorable for intensification.  Danas will move over water where the Sea Surface Temperature is near 31°C.  So, there is plenty of energy in the upper ocean.  The strong upper level easterly winds are expected to weaken somewhat during the next several days.  If those winds weaken, then there will be less vertical wind shear and Tropical Storm Danas could strengthen.  If the upper level winds remain strong, then Danas will not strengthen and it could weaken to a tropical depression.  The forecast is for very slow intensification during the next 24 to 48 hours.

Since there are not a lot of taller thunderstorms near the center of Tropical Storm Danas, it will be steered by the winds in the lower troposphere.  Danas will move around the western end of a subtropical ridge over the Western North Pacific Ocean.  The ridge will turn Danas toward the north on Wednesday.  On its anticipated track the center of Tropical Storm Danas will remain east of Luzon.  The center of Danas could be near southeastern Taiwan in 24 to 36 hours.  Tropical Storm Danas could be near the east coast of China in about three days.  The primary risks will be locally heavy rain and flash floods.
