Tropical Storm Sanba to bring rain on Sunday

By Shelley Shan  /  Staff reporter

Tropical Storm Sanba began to form yesterday morning and is likely to affect the nation’s weather system on Sunday, the Central Weather Bureau said yesterday.

As of 2pm yesterday, the center of the storm was located 1,490km southeast of Manila. It was moving northwesterly at a speed of 14kph.

The bureau forecast that Sanba was likely to cruise through the sea area near the nation’s east coast before moving northward, adding that the chances it would hit Taiwan directly were low.

Nevertheless, the bureau warned that Sanba’s circumfluence would bring rain to the nation’s northern and northeastern regions.

Sanba is also the nation’s first tropical storm formed during the fall. Earlier this month, the bureau forecast that eight more typhoons and tropical storms could form in the northwest Pacific Ocean between this month and November, and that one or two typhoons could hit the nation during this period of time.

According to the bureau, the East Asian Continent is generally influenced by the Mongolian high pressure system during the fall and winter. Cold north or northwest winds would blow past the north of the Yangtze River and change direction, becoming northeast winds when they reach areas south of the river. Taiwan is located on the southeast edge of the Mongolian high pressure system and so it often experiences northeasterly wind, or the northeast monsoon.

Bureau forecaster Lo Ya-yin (羅雅尹) said the nation would experience northeasterly winds on Friday and Saturday, with temperatures dropping by four to five degrees to about 30°C during the day. The nighttime temperature would be between 24°C and 25°C, she added.
