Tropical Storm Nalgae caused floods and mudslides in the Philippines on Saturday. At 5:00 p.m. EDT on Saturday the center of Tropical Storm Nalgae was located at latitude 15.9°N and longitude 119.8°E which put it about 100 miles (160 km) north-northwest of Manila, Philippines. Nalgae was moving toward the northwest at 15 m.p.h. (24 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.

Tropical Storm Nalgae dropped heavy rain as it moved across Luzon on Saturday. Heavy rain caused floods and mudslides in some locations. There were reports of deaths and injuries that were caused by the floods and mudslides. Tropical Nalgae did weaken as it moved across Luzon, but some bands were still dropping heavy rain in places. The center of Nalgae was about to move over the South China Sea. Winds to tropical storm force extended out 175 miles (280 km) from the center of Nalgae’s circulation.

Tropical Storm Nalgae will move through an environment mostly favorable for intensification during the next 36 hours. Nalgae will move over water where the Sea Surface Temperatures are near 29˚C. Nalgae will move under the western side of an upper level ridge over the Western North Pacific. The upper level ridge will produce southerly winds that will blow toward the top of Nalgae’s circulation. Those winds will cause vertical wind shear, but the wind shear will not be strong enough to prevent intensification. Tropical Storm Nalgae is likely to intensify when it move over the South China Sea. Nalgae could strengthen to a typhoon during the next 36 hours.

Tropical Storm Nalgae will move around the western end of a high pressure system over the Western North Pacific Ocean. The high pressure system will steer Nalgae toward the northwest during the next 36 hours. On its anticipated track Tropical Storm Nalgae will move away from northern Luzon. The heavy rain in the Philippines will diminish when Nalgae moves farther away from Luzon.

Tropical Storm Nalgae brought wind and rain to the Philippines on Friday. At 5:00 p.m. EDT on Friday the center of Tropical Storm Nalgae was located at latitude 14.3°N and longitude 123.1°E which put it about 175 miles (280 km) east of Manila, Philippines. Nalgae was moving toward the west-northwest at 22 m.p.h. (35 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 988 mb.

Tropical Storm Nalgae strengthened on Friday as it approached southeastern Luzon. The inner end of a rainband wrapped around the eastern side of the center of Nalgae. Bands of showers and thunderstorms were revolving around the core of Tropical Storm Nalgae. Storms near the core generated upper level divergence that pumped mass away from the tropical storm. Winds to tropical storm force extended out 200 miles (320 km) from the center of Nalgae.

Tropical Storm Nalgae will move around the southern side of a high pressure system over the Western North Pacific Ocean. The high pressure system will steer Nalgae toward the west-northwest during the next 24 hours. On its anticipated track Tropical Storm Nalgae will move quickly across Luzon. Nalgae will continue to produce gusty winds and locally heavy rain in Luzon during the next 24 hours. Heavy rain is likely to cause flash floods in some locations.

Tropical Storm Nalgae will move through an environment mostly favorable for intensification during the next 36 hours. When the center of Nalgae is over water, it will move over water where the Sea Surface Temperatures are near 29˚C. An upper level ridge over the Western North Pacific will produce northeasterly winds that will blow toward the top of Nalgae’s circulation. Those winds will cause vertical wind shear, but the wind shear will not be strong enough to prevent intensification. Tropical Storm Nalgae will be unlikely to intensify while the center of its circulation is over Luzon. Nalgae could intensify when the center moves over the South China Sea.
