What are the 'New Disaster Weather Information' rules as of May 29? TBS Radio publishes detailed guide by meteorologist Yoshio Saito.

The 'New Disaster Weather Information' system launched on May 29, 2026 (Friday), significantly changing the mechanism for weather alerts. Previously, categories like 'warnings,' 'caution information,' and 'danger information' lacked unified naming conventions, making them difficult to understand. This revision reorganizes these categories to ensure residents can act without hesitation when deciding when to evacuate.

Key changes include the addition of new 'river flooding' watch/alert categories and the consolidation of flood alerts into the 'heavy rain' category. Understanding these new rules is the first step toward saving lives amidst increasingly severe natural disasters.
