Heavy Rain Alert Upgraded to Yellow; Shanghai Activates Level III Flood and Typhoon Emergency Response

The Shanghai Meteorological Bureau upgraded its heavy rain alert from blue to yellow at 5:26pm today, as the city braces for intense downpours. According to the forecast, short-term heavy rainfall of 40-60mm per hour is expected across the city before midnight tonight.

Residents are urged to remain vigilant, as the strong precipitation may cause localized flooding, particularly in low-lying and flood-prone areas. Relevant departments have been advised to reinforce drainage and flood prevention measures in susceptible zones.

In response, Shanghai has officially activated a Level III (Yellow) emergency response for flood and typhoon control. This marks a heightened state of readiness to ensure public safety and infrastructure stability amid worsening weather conditions.

Earlier issued alerts – including the yellow lightning warning, blue gale warning, orange heat wave alert, and yellow rainstorm warning – remain in effect, underscoring the city's complex and volatile weather conditions today.

Citizens are advised to stay indoors during severe weather, avoid waterlogged roads, and closely monitor official updates.
