Has now been downgraded to a TS after landfall in East China. I thought this belatedly should have a thread in TS Discussion for posterity and future reference, although it will soon be passed I would welcome any contributions from a more "technical viewpoint".

Tropical Storm Haikui is headed for landfall in southeastern China, and NASA's Aqua satellite caught a stunning image of its size and its ragged, but wide eye when it was a typhoon earlier today, August 7. As a result of interaction with land, Haikui has weakened to a tropical storm.

When NASA's Aqua satellite passed over Typhoon Haikui on August 6, 2012 at 12:35 a.m. EDT the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument onboard captured an image of the storm as it was approaching China. The MODIS image clearly showed Haikui's ragged and elongated eye and the northwestern edge of the storm was already over southeastern China at that time.

By August 7 at 1500 UTC (11 a.m. EDT), Haikui dropped down to tropical storm status with maximum sustained winds near 60 knots (69 mph/111 kmh) as it approached the China coastline. Tropical-storm-force winds extend out as far as 100 nautical miles (115 miles/185 km) from the center. Haikui was located approximately 225 nautical miles (259 miles/416.7 km) south-southeast of Shanghai, China, near 28.4 North latitude and 122.5 East longitude. It was headed northwest at 8 knots. Because Haikui was generating 28-foot-high (8.5 meter) seas, residents along the coast can expect dangerous surf, flooding, and coastal erosion.

The Joint Typhoon Warning Center forecasts Typhoon Haikui to maintain its current track and make landfall south of Zhoushan, China by 10 p.m. EDT/U.S. today, August 7 and then turn to the northeast.

ASA's Aqua Satellite Sees Tropical Storm Haikui Make Landfall in China

Typhoon Haikui weakened to a tropical storm just before landfall in China. Eight hours after landfall, NASA's Aqua satellite still showed a strong and organized tropical storm moving inland.China's National Meteorological Center (NMC) said that Tropical Storm Haikui, made landfall in Zhejiang province on August 8 at 3:20 a.m. local time (19:20 UTC or 3:20 p.m. EDT/U.S., August 7), about 140 miles (225 km) south of Shanghai. The Joint Typhoon Warning Center's last official warning on Haikui was issued on August 8 at 0300 UTC (11 a.m. local time/Shanghai). At that time Haikui's maximum sustained winds were near 60 knots (69 mph/111.1 kmh) and it was located about 95 miles south of Shanghai, near 29.7 North latitude and 121.3 East longitude. It was moving to the northwest at 9 knots (10.3 mph/16.6 kmh).

By 5 p.m. EDT Shanghai local time on August 8 Haikui was located near the city of Huzhou. NMC reported heavy rainfall with totals as high as 17 inches (434 millimeters) in Xiangshan, Taizhou, and Ninghai, all located in the southeast coastal province of Zhejiang.A visible image of Tropical Storm Haikui was captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument that flies onboard NASA's Aqua satellite on August 8, 2012 at 0520 UTC (1:20 a.m. EDT/1:20 p.m. Shanghai local time) after it made landfall south of Shanghai, China. The MODIS image showed an organized tropical storm with high thunderstorms around the center that cast shadows on the lower surrounding storms. Those higher thunderstorms were likely dropping heavy rainfall. Haikui is moving northwest and is expected to weaken and dissipate over land in the next couple of days.

• Typhoon Haikui has brought heavy downpours to east China and killed three people there.
• It has affected n 4.03 million people and caused economic losses of 10 billion yuan in Zhejiang.
• Although Haikui has weakened, it will still bring heavy rains to central and northern Zhejiang.

More than 130,000 people have been affected and about 10,000 residents have been relocated in east China's Jiangxi Province as a result of typhoon Haikui, local authorities said Friday.
