Tropical Depression Drops Rain on Mindanao

Tropical Depression 03W dropped rain on Mindanao on Thursday. At 11:00 p.m. EDT on Thursday the center of Tropical Depression 03W was located at latitude 7.7°N and longitude 124.7°E which put it about 45 miles (75 km) northwest of Davao, Philippines. The tropical depression was moving toward the west at 12 m.p.h. (19 km/h). The maximum sustained wind speed was 30 m.p.h. (50 km/h) and there were wind gusts to 40 m.p.h. (65 km/h). The minimum surface pressure was 1004 mb.

Tropical Depression 03W made landfall on the east coast of Mindanao near Manay on Thursday. The depression generated showers and thunderstorms as it moved over Mindanao. Some of the rainbands revolving around the center of the tropical depression dropped heavy rain over parts of Mindanao. The circulation around Tropical Depression 03W weakened steadily after it moved over land. It is likely to continue to weaken as it moves west across the southern Philippines.

Tropical Depression Forms East of Mindanao

Tropical Depression 03W formed east of Mindanao on Wednesday. At 5:00 p.m. EDT on Wednesday the center of Tropical Depression 03W was located at latitude 7.1°N and longitude 129.6°E which put it about 275 miles (475 km) east of Davao, Philippines. The tropical depression was moving toward the west-northwest at 7 m.p.h. (11 km/h). The maximum sustained wind speed was 35 m.p.h. (55 km/h) and there were wind gusts to 45 m.p.h. (75 km/h). The minimum surface pressure was 1001 mb.

More thunderstorms formed near the center of a small low pressure system east of Mindanao on Wednesday and the Joint Typhoon Warning Center designated the system as Tropical Depression 03W. More thunderstorms were also forming in bands that were revolving around center of the depression. Storms near the center of circulation were began to generate upper level divergence that pumped mass away from the tropical depression.

Tropical Depression 03W will move through an environment favorable for intensification during the next 24 hours. The depression will move over water where the Sea Surface Temperatures are near 30°C. It will move under the middle of a small upper level ridge east of the Philippines. The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear. Tropical Depression will intensify during the next 24 hours and it is likely to strengthen to a tropical storm.

Tropical Depression 03W will move south of a subtropical high pressure system over the Western North Pacific Ocean. The high pressure system will steer the depression toward the west-northwest during the next 48 hours. On its anticipated track, Tropical Depression 03W will approach the east coast of Mindanao in a little over 24 hours. It will likely be a tropical storm when it approaches the coast. The system will drop locally heavy rain over Mindanao and flash floods could occur.

Tropical Storm Dujuan Moves Toward Mindanao

Tropical Storm Dujuan moved toward Mindanao on Friday. At 10:00 a.m. EST on Friday the center of Tropical Storm Dujuan was located at latitude 6.2°N and longitude 130.1°E which put it about 320 miles (515 km) east of Davao, Philippines. Dujuan was moving toward the west at 9 m.p.h. (11 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 994 mb.

The distribution of thunderstorms around Tropical Storm Dujuan was asymmetrical. The strongest thunderstorms were occurring in bands in the northwestern quadrant of Dujuan. Bands in the rest of the tropical storm consisted primarily of showers and lower clouds. Storms northwest of the center of circulation generated upper level divergence which pumped mass away to the northwest of the tropical storm. Winds to tropical storm force extended out 200 miles (320 km) from the center of Dujuan.

Tropical Storm Dujuan will move through an environment unfavorable for intensification during the next 48 hours. Dujuan will move over water where the Sea Surface Temperature is near 29°C. So, there will be enough energy in the upper ocean to support intensification. However, Tropical Storm Dujuan will move under the southern part of an upper level ridge over the Western North Pacific Ocean. The ridge will produce strong easterly winds which will blow toward the top of Dujuan. Those winds are causing the asymmetrical distribution of thunderstorms and they will create strong vertical wind shear. In addition, a surface high pressure system over eastern Asia will produce strong northeasterly winds in the lower levels. Those winds will transport drier air over the Philippines. The combination of vertical wind shear and drier air will likely prevent further intensification of Tropical Storm Dujuan. Dujuan is likely to weaken gradually during the next 36 hours.

Tropical Storm Dujuan will move south of a high pressure system over the Western North Pacific Ocean. The high will steer Dujuan toward the west-northwest during the next several days. On its anticipated track Tropical Storm Dujuan could approach northeastern Mindano in 36 hours. Dujuan could be a tropical storm when it reaches Mindanao. It will bring gusty winds and locally heavy rain to Mindano and other parts of the southern Philippines.

Tropical Storm Dujuan Develops East of Mindanao

Tropical Storm Dujuan developed east of Mindanao on Thursday. At 10:00 a.m. EST on Thursday the center of Tropical Cyclone Dujuan was located at latitude 7.3°N and longitude 131.6°E which put it about 430 miles (695 km) east of Davao, Philippines. Dujuan was moving toward the west-northwest 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 1000 mb.

The circulation around an area of low pressure east of the Philippines strengthened on Thursday morning and the Japan Meteorological Agency designated the system as Tropical Storm Dujuan. The distribution of thunderstorms around Tropical Storm Dujuan was asymmetrical. The strongest thunderstorms were occurring in bands in the western half of Dujuan. Bands in the eastern half of the tropical storm consisted primarily of showers and lower clouds. Storms west of the center of circulation began to generate upper level divergence which pumped mass away to the west of the tropical storm. Winds to tropical storm force extended out 100 miles (160 km) from the center of Dujuan.

Tropical Storm Dujuan will move through an environment somewhat favorable for intensification during the next 36 hours. Dujuan will move over water where the Sea Surface Temperature is near 29°C. It will move under the southern part of an upper level ridge over the Western North Pacific Ocean. The ridge will produce easterly winds which will blow toward the top of Tropical Storm Dujuan. Those winds will create moderate vertical wind shear and they are causing the asymmetrical distribution of thunderstorms. The wind shear will inhibit intensification, but it will not be strong enough to prevent Dujuan from strengthening. Tropical Storm Dujuan is likely to intensify gradually during the next 36 hours.

Tropical Storm Dujuan will move south of a high pressure system over the Western North Pacific Ocean. The high will steer Dujuan toward the west-northwest during the next several days. On its anticipated track Tropical Storm Dujuan could approach northeastern Mindano in 48 hours. Dujuan could bring gusty winds and locally heavy rain to Mindano and other parts of the southern Philippines.
