The Hong Kong Observatory issued thunderstorm warnings on June 14, impacting Kowloon, Hong Kong Island, and New Territories East. While recent yellow rainstorm warnings have been canceled, meteorologists expect heavy rain to persist through the following day before weather conditions improve for the upcoming Dragon Boat Festival weekend.
Why are thunderstorm warnings being issued across Hong Kong?
The Hong Kong Observatory issued thunderstorm warnings starting at 7:25 PM on June 14. According to reports from Zi Jing Wang, these alerts were extended into the following day, with some warnings remaining effective until 12:30 PM and others until 2:00 PM.

The warnings specifically targeted residents in Kowloon, Hong Kong Island, and the eastern parts of the New Territories. The intensity of these weather events can shift rapidly. According to on.cc, whether a yellow rainstorm warning escalates into a red rainstorm warning depends entirely on how local thunderstorm cells develop.
“The development of thunderstorm areas determines if a yellow rainstorm warning will escalate to a red warning.” — on.cc
This volatility requires residents to monitor official updates closely, as the transition between warning levels can happen without significant notice.
How can residents manage potential street flooding?
Heavy rainfall often leads to immediate drainage challenges in urban areas. The Drainage Services Department (DSD) has instructed the public to report any instances of street flooding as soon as they are discovered.
According to RTHK, the DSD maintains a 24-hour hotline specifically for these reports. Residents are encouraged to call this number to ensure that emergency teams can respond to localized flooding and prevent water from accumulating in high-traffic areas or residential entrances.
When will the weather stabilize for the weekend?
While the immediate threat of a yellow rainstorm warning has passed, the weather pattern remains unsettled. The Observatory recently canceled the yellow rainstorm signal, but Sing Tao Headline reports that heavy rain is still expected to occur tomorrow.
The current weather cycle shows a contrast between immediate heavy downpours and a projected period of stability. According to Sing Tao Headline, conditions are expected to improve significantly during the Dragon Boat Festival and the following weekend.
Comparison of Weather Trends
The following table summarizes the transition from the current unsettled period to the upcoming holiday period based on official forecasts:

| Immediate/Tomorrow | Heavy rain and thunderstorms | Sing Tao Headline |
| Dragon Boat Festival | Improving/Better weather | Sing Tao Headline |
Did you know? The escalation from a yellow to a red rainstorm warning is a measure of the intensity and localized nature of the rainfall, rather than just the total amount of rain over a long period.
