Tropical Storm Malakas Passes Between Guam and Yap

Tropical Storm Malakas passed between Guam and Yap on Saturday night. At 11:00 p.m. EDT on Saturday the center of Tropical Storm Malakas was located at latitude 12.0°N and longitude 139.7°E which put it about 345 miles (555 km) west of Guam. Malakas was moving toward the northwest at 29 m.p.h (46 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 982 mb.

Tropical Storm Malakas brought gusty winds and heavy rain to Fais on Saturday night as it passed between Guam and Yap. The circulation around Malakas strengthened on Saturday. The heaviest rain was occurring in a band that was wrapping around the southern side of the center of Tropical Storm Malakas. Other bands of showers and thunderstorms were revolving around the center of Malakas. 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 130 miles (210 km) from the center of Malakas.

Tropical Storm Malakas will move through an environment mostly favorable for intensification during the next 36 hours. Malakas will move over water where the Sea Surface Temperatures are near 29˚C. It will move under the southwestern part of an upper level ridge over the Western North Pacific Ocean. The ridge will produce southeasterly winds that will blow toward the top of Malakas’ circulation. Those winds will cause moderate vertical wind shear. The wind shear will inhibit intensification, but the shear will not be large enough to prevent strengthening. Tropical Storm Malakas will intensify during the next 36 hours. Malakas could strengthen to a typhoon during the next 24 hours.

Tropical Storm Malakas will move around the western part of a high pressure system over the Western North Pacific Ocean during the next several days. The high pressure system will steer Malakas toward the northwest during the next 24 hours. On its anticipated track Tropical Storm Malakas will remain west of the Marianas during the next several days. Malakas will move more toward the north when it reaches the western end of the high pressure system. Malakas could approach Iwo To in four days.

Elsewhere over the Western North Pacific Ocean, former Tropical Depression 03W strengthened to Tropical Storm Megi near the Philippines. At 11:00 p.m. EDT on Saturday the center of Tropical Storm Megi was located at latitude 11.3°N and longitude 125.9°E which put it about 25 miles (40 km) east of Guiuan, Philippines. Megi was moving toward the northwest 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 998 mb. Tropical Storm Megi could drop heavy rain over Samar and Leyte. Locally heavy rain could cause flash floods in some locations.

Tropical Storm Malakas Spins South-southwest of Guam

Tropical Storm Malakas spun south-southwest of Guam on Friday night. At 11:00 p.m. EDT on Friday the center of Tropical Storm Malakas was located at latitude 7.4°N and longitude 144.1°E which put it about 460 miles (740 km) south-southwest of Guam. Malakas was moving toward the north 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 997 mb.

An upper level ridge over the Western North Pacific strengthened on Friday and that increased the vertical wind shear affecting Tropical Storm Malakas. The increased wind shear prevented Malakas from strengthening on Friday. When the upper level ridge strengthened, the easterly winds blowing toward the top of Malakas’ circulation strengthened. Those stronger upper level winds increased the vertical wind shear and they caused the distribution of thunderstorms around Tropical Storm Malakas to become asymmetrical. The strongest thunderstorms were occurring in bands in the western half of Malakas’ circulation. Bands in the eastern half of the tropical storm consisted primarily of showers and lower clouds. Winds to tropical storm force extended out 90 miles (145 km) from the center of circulation.

Tropical Storm Malakas will move through an environment more favorable for intensification during the next 36 hours. Malakas will move over water where the Sea Surface Temperatures are 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 that will blow toward the top of Malakas’ circulation. Those winds will cause some vertical wind shear, but the shear is forecast to decrease during the weekend. Tropical Storm Malakas will intensify during the next 36 hours. Malakas could strengthen to a typhoon during the weekend.

Tropical Storm Malakas will move around the southwestern part of a high pressure system over the Western North Pacific Ocean during the next several days. The high pressure system will steer Malakas toward the northwest. On its anticipated track Tropical Storm Malakas could pass between Guam and Yap during the weekend.

Elsewhere over the Western North Pacific Ocean, Tropical Depression 03W developed east of the Philippines. At 11:00 p.m. EDT on Friday the center of Tropical Depression 03W was located at latitude 10.8°N and longitude 126.8°E which put it about 265 miles (425 km) southeast of Legazpi, Philippines. The tropical depression was moving toward the south-southwest at 4 m.p.h (6 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 1006 mb.

Tropical Depression 02W Strengthens to Tropical Storm Malakas

Former Tropical Depression 02W strengthened to Tropical Storm Malakas south of Guam on Thursday. At 11:00 p.m. EDT on Thursday the center of Tropical Storm Malakas was located at latitude 5.3°N and longitude 146.2°E which put it about 605 miles (970 km) south of Guam. Malakas was moving toward the northwest at 8 m.p.h (13 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 997 mb.

Tropical Storm Malakas was strengthening on Thursday night. Malakas exhibited more organization on satellite images. More thunderstorms were developing in all parts of the circulation around Tropical Storm Malakas. Bands of showers and thunderstorms were revolving around the center of Malakas. 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 140 miles (225 km) in the northern half of Malakas’ circulation. Winds to tropical storm force extended out 90 miles (145 km) in the southern half of the circulation.

Tropical Storm Malakas will move through an environment favorable for intensification during the next 36 hours. Malakas will move over water where the Sea Surface Temperatures are 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 that will blow toward the top of Malakas’ circulation. The winds will also be blowing from the east at most other levels in the troposphere. Since the winds will be blowing from the same direction at different levels, there will be little vertical wind shear. Tropical Storm Malakas will intensify during the next 36 hours. Malakas could strengthen to a typhoon within the next 48 hours.

Tropical Storm Malakas will move around the southwestern part of a high pressure system over the Western North Pacific Ocean during the next several days. The high pressure system will steer Malakas toward the northwest. On its anticipated track Tropical Storm Malakas could pass between Guam and Yap in 48 hours.
