Northern Taiwan to see wet weather Friday and Saturday

Taipei, July 25 (CNA) Northern Taiwan can expect to see sporadic showers or thunderstorms with the possibility of localized heavy rain from Friday to Saturday due to the effect of a tropical depression, according to the Central Weather Administration (CWA).

Brief afternoon showers could also occur in other areas around the country during this period, with a chance of heavy rain in some mountainous regions, as the tropical depression's outer bands affect Taiwan, the CWA said.

As of 8 a.m. on Friday, the depression (TD10) that was formerly Tropical Storm Francisco was located 290 kilometers northeast of Taipei, moving west at 15 kilometers per hour, according to CWA data.

The weather administration has also issued heavy rain advisories for the cities and counties of Keelung, Taipei, New Taipei, Taoyuan, Hsinchu, Miaoli, Taichung and Yilan.

The CWB defines heavy rain as accumulated rainfall of 80 millimeters or more within 24 hours or 40 mm or more in an hour.

Independent meteorologist Wu Der-rong (吳德榮) said TD10 and Tropical Storm Co-May were rotating counterclockwise under a Fujiwara effect, a phenomenon that occurs when two nearby storm vortices move around each other.

Tropical Storm Co-May is currently moving northeast and is expected to gradually weaken after passing over Luzon Island in the northern Philippines, Wu said.

Meanwhile, another tropical storm, Krosa, which has formed in waters north of Guam in the Western Pacific, will not have a direct impact on Taiwan, Wu added.

Due to the influence of TD10 and Co-May, wet weather can be expected across northern and central Taiwan from Friday and into the weekend, according to Wu.
