TAIPEI (Taiwan News) -- Super Typhoon Mangkhut has continued to gain in intensity but has shifted south and appears to be headed toward the northern Philippine island of Luzon, while it appears that Taiwan will be largely spared from its effects, according to the Central Weather Bureau (CWB).

CWB forecaster Wu Yin-fan (吳依帆) today said that the probability of issuing a sea warning has diminished as Mangkhut has shifted to the south, but there will still be significant rainfall in southern and eastern Taiwan. As of 2:00 a.m. this morning, Super Typhoon Mangkhut was located 1,510 kilometers southeast of Eluanbi and was packing maximum sustained winds of 198 kilometers per hour with gusts of up to 244 kilometers per hour, according to the CWB.

It is estimated that Mangkhut will come closest to Taiwan from Friday evening (Sept. 14) to Saturday, but due to the intensification of a Pacific high pressure system, the typhoon's path has shifted further south, pushing it further away from the country.

Wu said that the typhoon's trajectory has shifted south and unless Mangkhut enlarges again, the probability of the bureau issuing a sea warning is currently low. Though the typhoon is not expected to make landfall in Taiwan, its periphery will bring significant rainfall to southern and eastern Taiwan starting at nightfall tomorrow and throughout Saturday.

The rainfall may be heavy at times and brief showers are also likely in mountainous areas of western Taiwan. Residents in these areas are reminded to take precautions for heavy downpours.

The weather today and tomorrow will be stable in much of Taiwan, with only eastern Taiwan to see scattered showers, while some mountainous areas in the rest of the country could see local afternoon thunderstorms.

Temperatures today will be balmy, with western Taiwan seeing highs ranging between 34 and 35 degrees Celsius, especially in Taipei, New Taipei City, Kaohsiung and Pingtung where the high could hit 35 degrees. Eastern Taiwan will be slightly milder with a high of 32 degrees.

PAGASA predicts that the typhoon will make landfall in Cagayan Province on the northern Philippine island of Luzon.
