BEIJING, Aug. 18 (Xinhua) -- Typhoon Rumbia, the 18th this year, has been moving northwest inland since it made landfall in Pudong New Area of Shanghai Friday, bringing heavy downpours and causing floods along its route.

The civil affairs department of east China's Anhui Province said that a total of 164,700 people has been adversely affected by typhoon Rumbia, and 2,226 people had been evacuated as of 3 p.m. Saturday.

Some 17,000 hectares of crops were inundated in the province, with the economic loss estimated at 93.41 million yuan (about 13.59 million U. S. dollars). No casualties have been reported.

According to the meteorological bureau of central China's Henan Province, the typhoon entered the province around 3 a.m. Saturday. Heavy rain has caused water logging in some cities in the eastern part of Henan.

China's national observatory on Saturday continued to issue an alert for typhoon Rumbia and upgraded a rainstorm alert with some regions bracing for heavy downpours.

The National Meteorological Center (NMC) upgraded the rainstorm alert to the orange level as rainstorms will batter Henan, Hebei, Shandong, Anhui and Jiangsu provinces Saturday and Sunday.

The country has a four-tier, color-coded weather warning system, with red representing the most severe, followed by orange, yellow and blue.

Some parts of Henan, Hebei, and Shandong provinces are expected to experience downpours of up to 350 mm within 24 hours, according to the NMC forecast.
