The weather has become changeable in Taiwan under the effects of seasonal northeasterly winds, pushing the mercury down on Thursday in the northern and eastern areas of the country, according to the Central Weather Bureau (CWB).
Because of the wind, the mercury fell to 19.1 degrees Celsius in Yilan and Suao in the northeast during the early morning hours, the bureau said.
Despite the sun providing some warmth, daytime temperatures were forecast to still be down to 23-25 degrees in the north and 26-27 degrees in Hualien and Taitung in the east, accompanied by occasional showers, with more rain predicted along the northern coast of Keelung and in Yilan, according to the CWB.
In central and southern areas, warmer and sunnier weather was forecast, with daytime temperatures expected to reach 29-30 degrees.
The bureau, however, alerted residents in those regions of big temperature changes between daytime and nighttime hours.
Wu Der-rong (???), a meteorologist and adjunct associate professor of atmospheric sciences at National Central University, said in his daily weather column that the seasonal winds will begin to weaken Friday, and as a result, temperatures will climb gradually with sporadic rain in the mountainous areas of eastern Taiwan, the north coast and Greater Taipei.
The mercury will rise to 27-29 degrees in northern Taiwan and 31 degrees in the center and south on Nov. 5-7 as the northeasterly winds turn into easterly winds, Wu forecast.
The former director of the CWB Weather Forecast Center, however, advised people on the island to be ready to feel cold again on Nov. 8, when a new wave of northerly winds will affect temperatures, bringing them down to below 20 degrees in northern Taiwan.
Meanwhile, the CWB said a tropical low air pressure system west of Guam has developed into Tropical Storm Meari, and that there is another tropical low pressure near Guam that could evolve into a typhoon.
Meari, which is moving in a northwesterly direction at a speed of 5-6 kilometers per hour, poses no threat to Taiwan for now because it is still far away, the bureau said, but the storm and the development of the other low pressure are being closely monitored nonetheless.
