Hong Kong to face brighter but hotter weather this week after days of heavy rain

Hong Kong anticipates a shift to sunnier conditions accompanied by scorching heat this week, according to the city's meteorological department. The Hong Kong Observatory issued an amber rainstorm warning for the second day in a row on Monday at 6:40am, following a similar alert on Sunday that persisted for over six hours before being lifted at 8:45am.

The warning was lifted due to heavy showers that deposited more than 30mm (1.2 inches) of rain in numerous locations, with up to 50mm recorded on Hong Kong Island. The Observatory cautioned that torrential rain could trigger flash flooding in areas with inadequate drainage.

A thunderstorm warning, which was extended to 10:30am on Monday, was issued on Sunday evening. The persistent influence of a broad trough of low pressure is expected to maintain heavy showers and squally thunderstorms along the coast of southern China throughout the day. However, as the trough weakens over the next few days, the weather will gradually become brighter, although showers will persist, according to the forecast.

Following a week of heavy rainfall last week, during which two red rainstorm signals were issued, the weather is projected to become drier and sunnier by the weekend. Tropical Cyclone Dolphin, currently over the western North Pacific, is anticipated to move towards the seas south of Japan, with the potential to approach the East China Sea area later in the week.

The outer subsiding air from the cyclone is expected to bring very hot weather to the southeastern coast of China, with temperatures reaching up to 33 degrees Celsius (91.4 Fahrenheit) on Friday. This hot weather will continue into the weekend, with very high daytime temperatures and isolated showers at night. The name Dolphin is derived from the Chinese white dolphins inhabiting Hong Kong's waters.
