TAIPEI - Tropical storm Goni, which is moving toward Taiwan, gained more strength on Sunday and may develop into a typhoon today or tomorrow, the Central Weather Bureau (CWB) said yesterday.
With a top wind speed of 25 meters per second, Goni is traveling in a west-northwesterly direction. Its impact on Taiwan may be felt on Friday at the earliest.
As Goni moves forward, twin tropical storm Atsani appears to have stagnated. As a result, the two storms have increased the distance between them and ceased to interact with each other, the CWB said.
As of press time, Goni was 2,700 kilometers away from Taiwan, and Atsani was 4,300 kilometers away. While the former is inching toward Taiwan, the latter is moving toward Japan.
With low wind shear, a moist atmosphere and ample ocean heat, chances are high that Goni will further intensify into a typhoon, meteorologists said.
Lin Ding-yi, of the CWB, said Goni's future trajectory won't be confirmed until Thursday, when the high-pressure system in the Pacific recedes. Its fringe wind is expected to affect Taiwan on Friday, Lin added.
However, much uncertainty still lies ahead. The closer Goni gets to Taiwan, the more difficult it will be to predict its future path, forecasters said.
More Rains in the Days Ahead
In the day ahead, due to the impact of a southwesterly wind, Central and Southern Taiwan may see brief rain during the day.
Strong convection may result in afternoon thundershowers in Northern Taiwan, and the public is advised to be alert to gusts, quick showers and sudden increases in water levels.
The CWB said a cold front is passing to the north of Taiwan, a sign that a winter weather system is now in development. The cold front will not land in Taiwan, but may bring more clouds and spots of rain to the north.
