From June 17th to 21st, significant rainfall is anticipated to affect the southwestern, Huanghuai, and Jianghuai regions. In response, the Central Meteorological Observatory has issued multiple warnings concerning potential mountain torrent disasters, flooding in small to medium-sized rivers, and geological hazards. Consequently, the Ministry of Transport has initiated a Level 4 defense protocol. This involves close coordination with transportation authorities across multiple provinces to fortify defensive measures, maintain round-the-clock vigilance, and ensure prompt reporting of information, ultimately safeguarding the dissemination of crucial travel safety advisories.
