Tomorrow's Weather / Will Typhoon Noul Cause Work and School Closures on July 24? Closest Approach to Taiwan on This Day! '3 Counties/Cities Hit Hardest by Torrential Rain' – CWA Releases Latest Path and Rainfall Timeline

The Central Weather Administration (CWA) stated that a tropical depression located over the sea east of the Philippines is just one step away from becoming a typhoon and is expected to strengthen into this year's 12th typhoon, 'Noul'. The CWA anticipates issuing a marine typhoon warning as early as 11:30 PM on the 23rd. Typhoon Noul is expected to make its closest approach to Taiwan during the daytime on Saturday (25th), with Hualien-Taitung and the Hengchun Peninsula under strict alert for torrential rain. There is also a chance of localized heavy rain in southern regions.

Typhoon Noul forming soon! CWA to issue marine warning by 11:30 PM tonight, closest to Taiwan on Friday the 25th, 3 areas on high alert for torrential rain

CWA forecaster Tseng Chao-cheng stated that if the tropical depression east of the Philippines develops into a typhoon tonight as expected, its radius of gale-force winds will be approximately 150 kilometers. The system is on the verge of becoming a typhoon; if it strengthens into Typhoon Noul, the 12th typhoon of the year, a marine typhoon warning is expected to be issued by 11:30 PM.

After formation, Noul is expected to move steadily, passing through the Bashi Strait and the sea south of Taiwan while maintaining a minimal typhoon intensity. However, once it enters the South China Sea, it still has room to intensify and could possibly make landfall in Guangdong, China, as a moderate typhoon.

Weather for the next week: 'Noul' closest to Taiwan on the 25th, Hualien-Taitung and Hengchun Peninsula on alert for torrential rain

Tomorrow, under the influence of Noul's outer circulation, rainfall will gradually expand. Rainfall in eastern Taiwan and the Hengchun Peninsula will become increasingly significant toward evening. Weather changes across Taiwan for the next week:

• Friday (July 24): Affected by the typhoon's outer circulation, rainfall gradually expands. Rainfall in eastern Taiwan and the Hengchun Peninsula becomes more pronounced toward evening. • Saturday (July 25): Typhoon closest to Taiwan. Heavy rain or torrential rain expected in Hualien-Taitung and Hengchun Peninsula. Southern regions should monitor for localized heavy rain in the afternoon. Short-lived showers possible in northern coastal areas, Greater Taipei, Yilan, and mountainous areas nationwide. • Sunday and Monday (July 26–27): Typhoon gradually moves away. Warm, moist southerly winds affect Taiwan, increasing chances of localized heavy rain in Taitung and Hengchun Peninsula. Afternoon thunderstorms with heavy rain possible across regions. • Tuesday (July 28): Moisture decreases. Heavy rain limited to mountainous areas north of central Taiwan. Hualien-Taitung and southern regions see localized brief showers. • Wednesday to Thursday (July 29–30): Moisture further decreases. Only Taitung and Hengchun Peninsula see brief showers.

Temperature outlook: Highs around 32–35°C nationwide

In addition to strong winds and heavy rain, the CWA has issued warnings for high temperatures and coastal wave conditions. On Friday (24th), due to foehn winds caused by southeast winds descending over mountains, northern areas may experience heatwaves. On Saturday (25th), the foehn effect expands to central and northern Taiwan, with localized highs possibly reaching 36–37°C. Elsewhere, temperatures will range from 32–35°C before rainfall.

From Thursday evening (23rd) through Sunday morning (26th), long-period waves are expected along eastern Taiwan (including Lanyu and Green Island), southwestern coasts, Hengchun Peninsula, and Penghu. The public is advised to avoid coastal activities.
