amber warning

The Hong Kong Observatory issued an amber rainstorm warning on Monday evening at 7:20 PM, signaling the potential for heavy rainfall. This warning was subsequently upgraded to a red rainstorm warning 30 minutes later, indicating more severe conditions. The red signal is the middle tier in Hong Kong's three-tier rainstorm warning system. The observatory had previously issued a general warning at 5 PM about impending rainfall and forecast heavy rain for the subsequent 24 hours. The issuance of these warnings highlights the immediate concern for heavy rain in the region. The amber warning, in particular, serves as an initial alert to the public about the possibility of significant rainfall and associated disruptions, preceding the more serious red warning.
