Tropical Storm Fengshen Brings Wind and Rain to Philippines

Tropical Storm Fengshen brought wind and rain to the Philippines on Saturday.  At 5:00 p.m. EDT on Saturday the center of Tropical Storm Fengshen was located at latitude 14.3°N and longitude 122.0°E which put the center about 115 miles (185 km) east-southeast of Manila, Philippines.  Fengshen was moving toward the west-northwest at 14 m.p.h. (22 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 Fengshen was maintaining its intensity as it brought wind and rain to the Philippines on Saturday.  Bands of showers and thunderstorms were dropping heavy rain on parts of Luzon.  Those same bands of thunderstorms were also producing gusty winds.

The strongest winds were occurring in the eastern side of Tropical Storm Fengshen.  Winds to tropical storm force extended out 90 miles (145 km) in the eastern half of Fengshen’s circulation.  The winds in the western side of Tropical Storm Fengshen were blowing at less than tropical storm force.

Tropical Storm Fengshen will move into an environment favorable for intensification when it moves over the South China Sea on Sunday.  Fengshen will move over water where the Sea Surface Temperatures are near 29°C. It will move under the middle of an upper level ridge that is over the Western North Pacific Ocean.  The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear.  Tropical Storm Fengshen is likely to maintain its intensity during the next 12 hours while it moves across Luzon.  Fengshen will intensify when it moves over the South China Sea on Sunday.

Tropical Storm Fengshen will move around the southern side of a high pressure system that is over the Western North Pacific Ocean.  The high pressure system will steer Fengshen toward the west-northwest during the next 24 hours.  On its anticipated track, Tropical Storm Fengshen will move across Luzon during the next 12 hours.  Fengshen will move over the South China Sea on Sunday.

Tropical Storm Fengshen will continue to bring strong winds and locally heavy rain to Luzon during the next 24 hours.  Heavy rain is likely to cause flash floods in some locations.  The weather in Luzon will start to improve later on Sunday when Tropical Storm Fengshen moves farther away.

Tropical Storm Francisco Develops South of Okinawa

Tropical Storm Francisco developed over the Western North Pacific Ocean south of Okinawa on Tuesday.  At 11:00 p.m. EDT on Tuesday the center of Tropical Storm Francisco was located at latitude 21.2°N and longitude 129.7°E which put the center about 415 miles (670 km) south-southeast of Okinawa.  Francisco was moving toward the northwest at 14 m.p.h. (22 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 996 mb.

A low pressure system over the Western North Pacific Ocean south of Okinawa strengthened on Tuesday and the Japan Meteorological Agency designated the system as Tropical Storm Francisco.

More thunderstorms formed near the center of Tropical Storm Francisco on Tuesday night.  Thunderstorms were also occurring in bands in the eastern side of Francisco’s circulation.  Bands in the western side of Tropical Storm Francisco consisted primarily of showers and lower clouds.  Storms near the center of Francisco generated upper level divergence that pumped mass away to the east and south of the tropical storm.  The removal of mass caused the surface pressure to decrease.

The circulation around Tropical Storm Francisco was large.  Winds to tropical storm force extended out 185 miles (295 km) from the center of Francisco’s circulation.

Tropical Storm Francisco will move through an environment somewhat favorable for intensification during the next 24 hours.  Francisco will move over water where the Sea Surface Temperatures are near 29°C.  It will move under the eastern side of an upper level low that is centered east of Taiwan.  The upper level low will produce southerly winds that will blow toward the top of Francisco’s circulation.  Those winds will cause moderate vertical wind shear.  The vertical wind shear will inhibit intensification, but the wind shear may not be enough to prevent intensification.  Tropical Storm Francisco is likely to intensify during the next 24 hours.

Tropical Storm Francisco will move around the western side of a high pressure system over the Western North Pacific Ocean.  The high pressure system will steer Francisco toward the northwest during the next 24 hours.  On its anticipated track, Tropical Storm Francisco will move toward the southern Ryukyu Islands.

Elsewhere over the Western North Pacific Ocean, Tropical Depression 11W formed north of Luzon.  At 11:00 p.m. EDT on Tuesday the center of Tropical Storm Depression 11W was located at latitude 18.5°N and longitude 120.1°E which put the center about 295 miles (470 km) north of Manila, Philippines.  The tropical depression was moving toward the west-southwest at 12 m.p.h. (19 km/h).  The maximum sustained wind speed was 35 m.p.h. (55 km/h) and there were wind gusts to 45 m.p.h. (75 km/h).  The minimum surface pressure was 997 mb.

Typhoon Man-Yi Strengthens to Equivalent of a Major Hurricane

Typhoon Man-yi strengthened to the equivalent of a major hurricane as it moved toward the Philippines on Friday.  At 4:00 p.m. EST on Friday the center of Typhoon Man-yi was located at latitude 12.3°N and longitude 127.2°E which put the center about 490 miles (790 km) east-southeast of Manila, Philippines.  Man-yi was moving toward the west-northwest at 15 m.p.h. (24 km/h).  The maximum sustained wind speed was 125 m.p.h. (200 km/h) and there were wind gusts to 155 m.p.h. (250 km/h).  The minimum surface pressure was 952 mb.

Typhoon Man-yi intensified to the equivalent of a major hurricane on Friday.  A circular eye with a diameter of 25 miles (40 km) was at the center of Man-yi’s circulation.  The eye was surrounded by a ring of thunderstorms and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving around the center of Man-yi’s circulation.  Storms near the center of Man-yi generated strong upper level divergence that pumped mass away from the typhoon in all directions.  The removal of large quantities of mass caused the surface pressure to decrease rapidly.

The circulation around Typhoon Man-yi was very symmetrical.  Winds to typhoon force extended out 30 miles (50 km) from the center of Man-yi’s circulation.  Winds to tropical storm force extended out 125 miles (200 km) from the center of Typhoon Man-yi.

The Hurricane Intensity Index (HII) for Typhoon Man-yi was 23.6.  The Hurricane Size Index (HSI) was 10.3 and the Hurricane Wind Intensity Size Index (HWISI) was 33.9.  Typhoon Man-yi was similar in size and intensity to Hurricane Dennis when Dennis hit Northwest Florida in 2005.

Typhoon Man-yi will move through an environment favorable for intensification during the next 24 hours.  Man-yi will move over water where where the Sea Surface Temperatures are near 29°C.  It will move under the middle of an upper level ridge over the Western North Pacific Ocean.  The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear.  Typhoon Man-yi is likely to continue to intensify during the next 24 hours.

Typhoon Man-yi will move around the southern side of a high pressure system over the Western North Pacific Ocean.  The high pressure system will steer Man-yi toward the west-northwest during the next 24 hours.  On its anticipated track, Typhoon Man-yi will reach southeastern Luzon in less than 18 hours.

Typhoon Man-yi will bring very strong winds and heavy rain to Luzon.  Heavy rain will cause flash floods and mudslides.  Man-yi could also cause a storm surge of up to 13 feet (4 meters) along the coast of Luzon.  Luzon has already been hit by a series of in recent weeks.  Typhoon Man-yi is capable of causing regional major damage.  Man-yi will seriously set back efforts to recover from the previous typhoons.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Usagi was bringing wind and rain to Taiwan.  At 4:00 p.m. EST on Friday the center of Tropical Storm Usagi was located at latitude 22.5°N and longitude 120.3°E which put the center about 25 miles (40 km) southwest of Kaohsiung, Taiwan.  Usagi was moving toward the north-northeast at 10 m.p.h. (16 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.  Heavy rain is likely to cause flash floods in Taiwan.
