Typhoon Maria Makes Landfall in China

The center of Typhoon Maria made landfall Lianjiang, China on Tuesday night.  At 11:00 p.m. EDT on Tuesday the center of Typhoon Maria was located at latitude 26.7°N and longitude 119.3°E which put it near Ningde, China.  Maria was moving toward the west-northwest at 22 m.p.h. (35 km/h).  The maximum sustained wind speed was 110 m.p.h. (175 km/h) and there were wind gusts to 135 m.p.h. (215 km/h).  The minimum surface pressure was 952 mb.

Two concentric eyewalls formed at the center of Typhoon Maria before it made landfall on the coast of China.  The inner eyewall was dissipating, but it still existed at the time of landfall.  The outer eyewall started to contract prior to landfall.  Winds to typhoon force extended out about 65 miles (105 km) from the center of circulation in the part of the circulation over water.  Winds to tropical storm force extended out about 235 miles (380 km) from the center in the part of the circulation over water.

Typhoon Maria brought strong winds and a storm surge to the coast of Zhejiang province when it made landfall.  Maria was also dropping heavy rain and flash flooding could occur.  Typhoon Maria was moving around the western end of a subtropical ridge over the Western North Pacific Ocean.  The ridge was steering Maria toward the west-northwest, but the typhoon is likely to turn more toward the northwest when it moves farther inland.  Typhoon Maria will weaken as it moves inland over eastern China, but it will still drop heavy rain and flooding will be a significant risk.

Typhoon Maria Drops Heavy Rain on Taiwan

Typhoon Maria dropped heavy rain on Taiwan on Tuesday after it brought wind and rain to the southern Ryukyu Islands.  At 5:00 p.m. EDT the center of Typhoon Maria was located at latitude 26.5°N and longitude 121.4°E which put it about 85 miles (135 km) north-northeast of Taipei, Taiwan.  Maria was moving toward the west-northwest at 22 m.p.h. (35 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 949 mb.

A primary rainband wrapped around the existing eye and eyewall in Typhoon Maria and the structure exhibited concentric eyewalls.  The inner eyewall started to weaken as more air converged and rose in the much larger outer eyewall.  The wind speeds decreased slowly as the inner eyewall weakened.  The concentric eyewalls altered the structure of Typhoon Maria and the size of the circulation increased.  Winds to typhoon force extended out about 70 miles (110 km) from the center of circulation.  Winds to tropical storm force extended out about 235 miles (380 km) from the center.

Typhoon Maria was moving around the southern side of a subtropical ridge over the Western North Pacific Ocean.  The ridge was steering Maria toward the west-northwest and a general motion in that direction is expected to continue for another 12 to 24 hours.  On its anticipated track the center of Typhoon Maria will pass north of Taiwan, but Maria will continue to drop heavy rain over Taiwan.  Maria will make landfall on the east coast of China near Fuding during the next 6 to 12 hours.  The typhoon will bring gusty winds, a storm surge and heavy rain to Zhejiang province in eastern China.  The heavy rain could cause flash floods.

Typhoon Maria Nears Southern Ryukyu Islands

Typhoon Maria neared the southern Ryukyu Islands on Monday night.  At 11:00 p.m. EDT on Monday night the center of Typhoon Maria was located at latitude 24.3°N and longitude 126.4°E which put it about 130 miles (210 km) east of Ishigaki, Japan.  Maria was moving toward the west-northwest at 18 m.p.h. (29 km/h).  The maximum sustained wind speed was 125 m.p.h. (205 km/h) and there were wind gusts to 155 m.p.h. (250 km/h).  The minimum surface pressure was 949 mb.

Typhoon Maria weakened slowly on Monday, but it remained a powerful typhoon.  Maria moved over some slightly cooler water mixed to the surface by recent Typhoon Prapiroon when it passed near the Ryukyu Islands.  Maria was unable to extract enough energy from the upper ocean to maintain the intense wind speeds it produced during the weekend.  However, Typhoon Maria was still the equivalent of a major hurricane.  There was a circular eye with a diameter of 35 miles (55 km).  A ring of strong thunderstorms surrounded the eye and the strongest winds were occurring in that ring of storms.  Several bands of thunderstorms were revolving around the core of Typhoon Maria.   Storms in the core were generating strong upper level divergence which was pumping mass away from the center of circulation.

Winds to typhoon force extended out about 70 miles (110 km) from the center of circulation.  Winds to tropical storm force extended out about 200 miles from the center.  The Hurricane Intensity Index (HII) for Typhoon Maria was 23.6.  The Hurricane Size Index (HSI) was 23.8 and the Hurricane Wind Intensity Size Index (HWISI) was 47.4.  Those indices indicated that Typhoon Maria was capable of causing widespread major damage.

Typhoon Maria will move through an environment capable of sustaining a strong typhoon on Tuesday.  Maria will move west of the cooler water mixed to the surface by previous Typhoon Prapiroon and it will move over water where the Sea Surface Temperature is near 29°C.  Typhoon Maria will move through a region where the upper level winds are weak and there will be little vertical wind shear.  Maria could weaken slowly on Tuesday if it is unable to extract enough energy from the upper ocean to sustain its circulation.  It could strengthen a little when it moves over slightly warmer water if it has time to extract more energy from the ocean.

Typhoon Maria was moving south of a subtropical ridge over the Western North Pacific Ocean.  The ridge was steering Maria toward the west-northwest and that general motion is expected to continue during the 36 hours.  On its anticipated track Typhoon Maria will reach the southern Ryukyu Islands in six to twelve hours.  Maria will bring destructive winds, heavy rain and a storm surge.  It will be capable of causing major damage to Miyako Jima, Ishigaki Jima, Iriomote Jima and the other islands in the southern Ryukyus.  The strongest part of Typhoon Maria will pass south of Okinawa, which could experience rainbands in the outer portion of the circulation.  Typhoon Maria will pass near northern Taiwan in about 18 hours.  It will bring strong winds and locally heavy rain to that area and flash floods could occur.  Maria could be near Fuding on the coast of China in about 24 hours.
