Group 1 - The first typhoon of the year, "Butterfly," formed on June 11, indicating the official start of the typhoon season, which is notably late this year compared to the average formation date of March 24 from 1991 to 2024, being over two months delayed [2][3] - "Butterfly" is currently classified as a tropical storm, with expectations of intensifying to a strong tropical storm or typhoon level (10-12 scale) due to favorable conditions such as high sea temperatures and moisture from the southwest monsoon [1][2] - The typhoon is projected to bring significant wind and rain impacts to Guangdong, with wind speeds reaching 7-10 levels in various coastal areas and heavy rainfall expected from June 13 to 15, marking the strongest precipitation event since the onset of the flood season [2][3] Group 2 - The delay in the typhoon season is attributed to a larger and stronger subtropical high-pressure system, which has suppressed the necessary convective development for typhoon formation, along with a southward shift in the tropical convergence zone and delayed summer monsoon onset [3]
