Typhoon Soudelor has made landfall being a direct hit across Taiwan. Towards the latter part of Friday, the storm approached the eastern coastline of Taiwan where it unleashed some torrential rain across the eastern side of the island. With a mountain barrier blocking its path, the storm unleashed torrents of rain across some localities while others were spared the worst.
Weather stations across the island have withstood the onslaught and this storm has been well documented by weather stations monitored by the Central Weather Bureau of Taiwan. As a result, an excellent analysis is provided.
Flooding rains, storms surges and gale force winds have already claimed lives (So far 4 according to CNN reporters). There is likely to be significant damage across the north east where the storm has hit hard. Prior to the storm making landfall, the Central Weather Bureau had issued numerous alerts and evacuations had been undertaken. Numerous cancellations were evident and emergency services were put on alert.
Judging by the rainfall and wind, this is clearly a major event.
Wind alerts for peak wind gusts of 58 metres per second with sustained winds of 48 metres per second were issued by the Central Weather Bureau. Torrential rain alerts were also issued for much of the east coast. This was justified as shown:-
Keelong - Wind gusts of 44.5 metres per second were being recorded at 5.30 am 8/8/15.
Pengjiay - Wind gusts of 55 metres per second were being recorded at 5.30 am 8/8/15.
Wuqi - Wind gusts of 50.5 metres per second were being recorded at 5.30 am 8/8/15.
These are coastal recordings.
By midnight 7/8 August a weather station at Taipingshan (Datong Township - Yilan County) had recorded 368 mm of rain (Location North east Taiwan). By 1.15 pm 8/8/15, another 608.5 mm of rain had fallen here (Accumulative total 976.5 mm).

Image 1 - CIMSS - Acquired 8 August showing the typhoon directly over the island. The eye filled in prior to landfall. An intense storm is crossing the northern part of the island and is impacting the heavily populated area of Taipei. The final forecast models showed a Category 3 typhoon with winds of 105 knots (Approx 194 km/h) with gusts to 130 knots (Approx 241 km/h) at or close to landfall.
The storm is moving off the west coast but heavy rain is now impacting the south west part of the island. The rainfall figures quoted here will increase especially over the west and south west coasts but will begin to ease over the east and north east which will allow emergency services to commence a clean up of the damage caused which is likely to be significant.
