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).

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.
