7. Typhoon MATSA (Gorio/09w) 
>> July 30-August 8, 2005
Matsa: contributed by Laos, means 'lady fish'
A. Storm Origins
On 30 July an area of convection developed approximately 100 nm east of Yap. It was included in JTWC's STWO at 0300 UTC 30 July when animated multi-spectral satellite imagery revealed consolidating deep convection over a weak LLCC. An upper-level analysis indicated that the disturbance was embedded in a moderate wind shear environment with favourable diffluence aloft. Based on improved organization, JTWC issued a TCFA at 30/1430 UTC followed by the first warning at 31/0000 UTC. TD-09W was quickly upgraded to a 35-kt tropical storm by JTWC at 31/0600 UTC, and named Matsa after JMA raised their 10-min avg MSW to 35 kts at 31/1200 UTC. Also, at 31/1200 UTC PAGASA assigned the name Gorio after the system had drifted into their AOR.
B. Track & Intensity History
Initially moving west to west-northwestward, Tropical Storm Matsa changed onto a northwesterly heading on 31 July under the steering influence of a mid-level ridge to the east. Continuing northwestwards, Matsa slowly strengthened and reached typhoon intensity at 0000 UTC on 2 August when it was located approximately 565 nm south of Okinawa. Intensification continued to be rather slow on 2 August and satellite imagery depictions were of limited deep convection in the northern semicircle and inhibited poleward outflow. There was little change on 3 August and the MSW hovered at 75 kts for the majority of the day.
However, on 4 August, things improved and Typhoon Matsa became better organized, reaching its peak intensity of 90 kts and 950 hPa at 04/1200 UTC when it was passing approximately 200 nm west-southwest of Okinawa, Japan. On 5 August Typhoon Matsa began to weaken as it headed northwestwards, lashing northern parts of Taiwan with torrential rains and gale-force winds as the storm passed by to the north. Continuing northwestward, Matsa made landfall near Wenling, China, as a minimal typhoon around 05/1800 UTC, the second tropical cyclone to affect the Chinese mainland in nearly two weeks. Once inland, Matsa was downgraded to a tropical storm at 06/0000 UTC, and JTWC issued the final warning at this time. JMA kept Matsa at tropical storm intensity as the cyclone turned northward over eastern China until 07/1200 UTC, when that agency released the last statement on this system.
NMCC estimated a peak intensity of 90-kts while all other Asian agencies estimated peak MSW of 80 kts.

C. Damage & Casualties
Ten deaths were reported by the Chinese media. More than 1.24 million people were evacuated ahead of the storm. Matsa caused extensive damage to property and agriculture in mainland China with monetary figures estimated at 14.5 million yuan (1.7 billion US dollars). Matsa also affected Taiwan. Rainfall totals of nearly 50 inches (1270 mm) fell in 30 hours over the northern part of the island, causing landslides and widespread flooding. Damages to agriculture were estimated at T$47 million (1.5 million US dollars). No deaths were reported in Taiwan.

D. Huang Chunliang Report from China
{Part I} Landfalls ================== According to the NMCC warnings, Typhoon 0509 (MATSA) made its first landfall near Ganjiang Town, Yuhuan County, Taizhou City, Zhejiang Province, around 05/1940 UTC (August) with a MSW of 45 m/s (90 kts) and a CP of 950 hPa. Crossing the Gulf of Yueqing, the typhoon made a second landfall near Qingjiang Town, Yueqing City (a sub-city of Wenzhou City), Zhejiang Province, around 05/2020 UTC with the MSW and CP unchanged. The weakening tropical cyclone then passed through Zhejiang, Anhui, Jiangsu and Shandong Provinces successively before the center of Tropical Storm Matsa entered the waters of the Bohai Sea from Shandong Peninsula around 08/0600 UTC. After fading into a tropical depression, Matsa made its final landfall near Longwangtang Town (38.8 N, 121.4 E), Lvshunkou District, Dalian City, Liaoning Province, around 08/2310 UTC with a MSW of 12 m/s (25 kts) and a CP of 995 hPa. Eventually, NMCC declared Matsa extratropical shortly after the final landfall. {Part II} Daily Top-10 Rainfall Obs from Taiwan Province ======================================================== [03/1600-04/1600Z] ------------------ Ranking Station ID City/County Rainfall ------------------------------------------------------------ 01 CWB 21D16 Hsinchu County 569.0 mm 02 CWB 21D15 Hsinchu County 565.0 mm 03 CWB C1E47 Miaoli County 549.0 mm 04 CWB C1D40 Hsinchu County 530.0 mm 05 CWB C0E41 Miaoli County 526.0 mm 06 CWB C1E48 Miaoli County 467.5 mm 07 CWB C1D41 Hsinchu County 461.0 mm 08 CWB C1E46 Miaoli County 445.5 mm 09 CWB 21C08 Taoyuan County 430.0 mm 10 CWB C1E72 Miaoli County 427.0 mm [04/1600-05/1600Z] ------------------ Ranking Station ID City/County Rainfall ------------------------------------------------------------ 01 CWB C1F89 Taitung County 843.0 mm 02 CWB C1F94 Taitung County 708.0 mm 03 CWB 21D15 Hsinchu County 688.0 mm 04 CWB 21D16 Hsinchu County 667.0 mm 05 CWB C1F87 Taitung County 595.0 mm 06 CWB 01A43 Taipei County 588.0 mm 07 CWB C1E46 Miaoli County 578.0 mm 08 CWB C1E72 Miaoli County 559.5 mm 09 CWB 21C08 Taoyuan County 558.0 mm 10 CWB C1F9H Taitung County 557.0 mm [05/1600-06/1600Z] ------------------ Ranking Station ID City/County Rainfall ------------------------------------------------------------ 01 CWB C1V27 Kaohsiung County 416.5 mm 02 CWB C1V30 Kaohsiung County 296.0 mm 03 CWB C1V22 Kaohsiung County 294.0 mm 04 CWB C1R16 Pingtung County 260.0 mm 05 CWB C1V16 Kaohsiung County 250.5 mm 06 CWB C1F87 Taitung County 250.0 mm 07 CWB C1V20 Kaohsiung County 248.0 mm 08 CWB C1V19 Kaohsiung County 246.5 mm 09 CWB C1V21 Kaohsiung County 238.5 mm 10 CWB C1F94 Taitung County 190.0 mm {Part III} Meteorological Obs from Zhejiang Province ==================================================== 1.
