TAIPEI (Taiwan News) -- The Central Weather Bureau (CWB) has issued a heavy rain advisory for 17 counties and cities in Taiwan today (July 22).

At 3:59 p.m. this afternoon, the CWB sent a text message warning residents across Taiwan of heavy rains, strong winds, lightning, and flooding in low-lying areas. The warning was to be in effect until 5:00 p.m. today.

The CWB issued a heavy rain advisory for Yilan County, Hsinchu County, Hsinchu City, Taoyuan City, Taitung City, Hualien County, Nantou County, Chiayi County, Yunlin County, Tainan City, Kaohsiung City, Taitung County, and Pingtung County for today. It issued an extremely heavy rain advisory for Taipei City, New Taipei City, Keelung City, and Miaoli County.

CWB forecaster Chen Chien-an (陳建安) said that heat convection in the afternoon would cause thunderstorms to spread across Taiwan. The signs of mesoscale convective system (MCS) development were particularly strong in central, northern, and eastern Taiwan.

With strong southeasterly winds blowing across Taiwan, the convective system will shift north. Therefore, thunderstorms in southern Taiwan should taper off sooner than in central Taiwan, while thunderstorms are expected to continue well into the night in northern Taiwan.
