Typhoon Kammuri Brings Wind and Rain to Southern Luzon

Typhoon Kammuri brought wind and rain to southern Luzon and Mindoro on Tuesday.  At 10:00 a.m. EST on Tuesday the center of Typhoon Kammuri was located at latitude 13.4°N and longitude 114.9°E which put it about 115 miles (185 km) south-southwest of Manila, Philippines.  Kammuri was moving toward the west at 13 m.p.h. (20 km/h).  The maximum sustained wind speed was 90 m.p.h. (145 km/h) and there were wind gusts to 115 m.p.h. (185 km/h).  The minimum surface pressure was 976 mb.

Typhoon Kammuri made landfall on the coast of southeastern Luzon near Sorsogon and Legaspi on Nonday.  After making landfall, the eye of Kammuri passed over San Pascual on the northern end of Burias Island.  The center of Kammuri moved across the Sibuyan Sea and the core of the typhoon passed over Marinduque Island and northern Mindoro.  Rainbands in the northern half of Typhoon Kammuri produced strong winds and dropped heavy rain over southern Luzon.  There were reports of widespread power outages.  There were also reports of several deaths associated with the passage of Kammuri.

Typhoon Kammuri weakened slowly as the circulation passed over land.  Increased friction caused the wind speed to gradually decrease and mountains disrupted portions of the circulation.  The eastern side of the eyewall weakened and the eye was no longer apparent on infrared satellite images.  The strongest thunderstorms were occurring in bands west and north of the center of circulation.  Bands southeast of the center consisted primarily of showers and lower clouds.  Winds to typhoon force extended out 60 miles (95 km) from the center of circulation.  Winds to tropical storm force extended out 250 miles (400 km) from the center.

Conditions will improve over southern Luzon and Mindoro as Typhoon Kammuri moves farther away.  Kammuri could maintain its intensity over even strengthen slightly during the next 24 hours as it moves over the warm water in the South China Sea.  Typhoon Kammuri will move over water where the Sea Surface Temperature is near 29°C.  Kammuri will reach the eastern end of a surface high pressure system over eastern Asia in about 24 hours.  Strong northeasterly winds will blow around the eastern end of the high and those winds will create strong vertical wind shear as they blow under southwesterly winds in the upper levels.  The strong wind shear is likely to cause Typhoon Kammuri to weaken quickly in about a day or so.

A ridge over the Western North Pacific Ocean will steer Typhoon Kammuri toward the west for about another 24 hours.  On its anticipated track Kammuri will move farther away from the Philippines.  When Typhoon Kammuri reaches the area of more vertical wind shear and the typhoon weakens, it will be steered by winds closer to the surface.  The strong northeasterly winds in that part of the atmosphere will steer Kammuri toward the south-southwest later this week.
