Typhoon Sarika Making Landfall on Hainan Island

The center of Typhoon Sarika is making landfall on Hainan Island near Qionghai and Wanning.  At 11:00 p.m. EDT on Monday the center of Typhoon Sarika was located at latitude 19.1°N and longitude 110.4°E which put it near Qionghai, China.  Sarika was moving toward the west-northwest at 11 m.p.h. (18 km/h).  The maximum sustained wind speed was 80 m.p.h. (130 km/h) and there were wind gusts to 100 m.p.h. (160 km/h). The minimum surface pressure was 976 mb.

The structure of Typhoon Sarika changed after it moved across the Philippines.  It developed a larger eye and more of the thunderstorms occurred in a primary rainband that wrapped around the western and southern parts of the circulation.  Sarika maintained that structure as it made landfall on Hainan Island, although were some indications in satellite imagery that they eye was contracting just prior to landfall.

Typhoon Sarika will weaken while the center passes over Hainan Island.  Sarika could be a tropical storm by the time the center emerges over the Gulf of Tongking.  The Sea Surface Temperature in the Gulf of Tongking is near 31°C.  So, evaporation could provide another source of energy and moisture while the center is over water.

Typhoon Sarika is being steered toward the west-northwest by a subtropical ridge and that general motion is expected to continue for another day or so.  On its anticipated track Typhoon Sarika will spend the next few hours moving across Hainan Island.  Sarika could make another landfall over northern Vietnam and southern China in about 24 to 30 hours.

The Hurricane Intensity Index (HII) was 11.5 for Typhoon Sarika.  The Hurricane Size Index (HSI) was 13.2 and the Hurricane Wind Intensity Size Index (HWISI) was 24.7.  These indices indicate that Typhoon Sarika is capable of causing regional, minor wind damage.  Sarika will also bring locally heavy which could cause floods over Hainan Island and parts of northern Vietnam and southern China.

Typhoons Sarika and Haima Churning Over Western North Pacific

Typhoons Sarika and Haima churned across the western North Pacific Ocean on Sunday.  At 11:00 p.m. EDT on Sunday the center of Typhoon Sarika was located at latitude 17.3°N and longitude 113.7°E which put it about 240 miles (390 km) east-southeast of Hainan Island.  Sarika was moving toward the west at 17 m.p.h. (27 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 970 mb.

At 11:00 p.m. EDT on Sunday the center of Typhoon Haima was located at latitude 13.2°N and longitude 135.9°E which put it about 935 miles (1505 km) east-southeast of Luzon.  Haima was moving toward the west-northwest at 17 m.p.h. (27 km/h).  The maximum sustained wind speed was 115 m.p.h. (185 km/h) and there were wind gusts to 145 m.p.h. (230 km/h).  The minimum surface pressure was 956 mb.

The circulation of Typhoon Sarika was disrupted somewhat when it crossed northern Luzon.  Thunderstorms around the eye weakened and breaks developed in the eyewall.  More and stronger thunderstorms developed around the center of circulation today and an eye has become more apparent on satellite imagery.  Numerous rainbands are rotating around the rest of the circulation.  Upper level divergence is increasing, which will increase the removal of mass from the core of Typhoon Sarika.

Typhoon Sarika is moving through an environment that is favorable for intensification.  Sarika is moving over water where the Sea Surface Temperature is above 30°C.  The upper level winds are weak and there is little vertical wind shear.  Typhoon Sarika is likely to intensify during the next 24 hours and it could intensify quickly if the eye finishes reforming.

A subtropical ridge is steering Typhoon Sarika toward the west .  Sarika is nearing the western end of the ridge and the typhoon is expected to turn more toward the northwest.  On its anticipated track Typhoon Sarika could be near Hainan Island in about 24 hours.  After it crosses Hainan Island, Marika could approach the coast of northern Vietnam in about two days.  Typhoon Sarika will bring strong winds and very heavy rain to Hainan.  It will weaken when it moves across Hainan, but Sarika could also bring gusty winds and heavy rain to northern Vietnam and parts of southeastern China.

Typhoon Haima is developing into a very strong and dangerous typhoon.  Haima has a small eye at the center of circulation.  The eye is surrounded by a ring of very strong thunderstorms.  Rainbands are rotating around the core of the circulation.  Thunderstorms in the core of Typhoon Haima are generating upper level divergence which is pumping out mass in all directions.

Typhoon Haima is moving through an environment that is favorable for continued intensification.  It is moving over water where the Sea Surface Temperature is 30°C.  The upper level winds are weak and there is little vertical wind shear.  Typhoon Haima is likely to continue to intensify and it could reach super typhoon status.

A subtropical ridge is steering Typhoon Haima toward the west-northwest and that general motion is expected to continue for several more days.  On its anticipated track Typhoon Haima could be near the northern end of Luzon in about three days.  It could be a very powerful typhoon at that time.

Powerful Typhoon Sarika Makes Landfall in Luzon

Powerful Typhoon Sarika made landfall in Luzon near Baler on Saturday.  At 11:00 a.m. EDT on Saturday the center of Typhoon Sarika was located at latitude 15.3°N and longitude 122.3°E which put it near Baler, Philippines and about 130 miles (210 km) east-northeast of Manila.  Sarika was moving toward the west-northwest at 12 m.p.h. (19 km/h).  The maximum sustained wind speed was 115 m.p.h. (185 km/h) and there were wind gusts to 145 m.p.h. (230 km/h).  The minimum surface pressure was 941 mb.

Sarika is a powerful, well organized typhoon.  It has a circular eye surrounded by a ring of strong thunderstorms.  Additional rainbands are rotating around the core of Sarika.  The core of Typhoon Sarika is generating well developed upper level divergence which is pumping out mass in all directions.  Typhoon Sarika was intensifying rapidly until it made landfall.

The Hurricane Intensity Index (HII) for Typhoon Sarika is 20.6.  The Hurricane Size Index (HSI) is 17.0 and the Hurricane Wind Intensity Size Index (HWISI) is 37.6.  These indices indicate that Typhoon Sarika is capable of causing regional major wind damage.  Typhoon Sarika will also generate a storm surge along the coast of Luzon north of the eye where the wind will push water toward the coast.  Sarika will also produce heavy rain over northern Luzon which will create a risk of flash flooding and mudslides.

A subtropical ridge is steering Typhoon Marika toward the west-northwest and that general motion is expected to continue for several more days.  On its anticipated track across Luzon the center of Typhoon Sarika will pass near San Jose City,  Baguio and Dagupan.  The center of Sarika could emerge over the South China Sea near the Lingayen Gulf.  The core of Typhoon Sarika will move across the Sierra Madre Mountains and the Cordillera Central.  Where winds blow up the slopes of the mountains, rising motion will be stronger and the rainfall will be heavier.  The mountains will also disrupt the airflow in the lower part of Sarika’s circulation and the typhoon will weaken.

It could take the center of Typhoon Sarika about 12 hours to move across Luzon.  The environment of the Sea China Sea will  be favorable for intensification.  The Sea Surface Temperature is warm and there will be little vertical wind shear.  If the core of the circulation remains reasonably intact, then Typhoon Sarika could intensify again while it moves across the South China Sea.  Sarika could eventually move near Hainan Island and into northern Vietnam in a few days.

Typhoon Sarika Near Catanduanes Island, Threatens Luzon

The center of Typhoon Sarika is located near Catanduanes Island and Sarika poses a serious threat to Luzon.  At 5:00 p.m. EDT on Friday the center of Typhoon Sarika was located at latitude 14.4°N and longitude 124.8°E which put it about 280 miles (455 km) east of Manila, Philippines.  Sarika was moving toward the west-northwest at 8 m.p.h. (13 km/h).  The maximum sustained wind speed was 75 m.p.h. (120 km/h) and there were wind gusts to 90 m.p.h. (145 km/h).  The minimum surface pressure was 981 mb.

The circulation of Typhoon Sarika is well organized.  An eye has appeared at times on conventional and microwave satellite imagery.  A primary rainband wrapped around the eye and strong thunderstorms are occurring in the eyewall.  Additional, well formed rainbands are rotating around the core of the circulation.  The convection around the core is generating well developed upper level divergence which is pumping away mass.

Typhoon Sarika is moving through a very favorable environment.  It is moving over water where the Sea Surface Temperature is near 30°C.  The upper level winds are weak and there is little vertical wind shear.  Typhoon Sarika will continue to intensify as long as the center stays over the water and it could intensify rapidly now that the circulation is well organized.

A subtropical ridge north of Sarika is steering the typhoon toward the west-northwest and that general motion is expected to continue for several more days.  On its anticipated track the center of Typhoon Sarika will remain north of Catanduanes Island.  It will pass just to the north of Daet and Labo on Saturday.  The center of Typhoon Sarika could be near or just to the north of the Polillo Islands in 12-16 hours.  Sarika could make a landfall near Baler on Luzon in 18-24 hours.

Sarika is a well organized intensifying typhoon.  It could bring strong winds to portions of northern Luzon.  Typhoon Sarika will also bring very heavy rain and create the potential for flash floods and mudslides.  Sarika will generate a storm surge in places where the wind blows the water toward the coast.
