The Observatory issued the Amber Rainstorm Warning on Thursday morning, less than seven hours after the signal was lowered.
It said at 8:35am that heavy rain exceeding 30 millimetres in an hour "has fallen or is expected to fall generally" over Hong Kong.
The amber signal was also issued on Wednesday night, and later upgraded to red before midnight before all warnings were cancelled at 1:40am on Thursday.
The forecaster warned of flooding in some low-lying and poorly drained areas, and urged those who are likely to be affected to take necessary precautions.
The warning came as the territory braced for the impact brought by the remnant of tropical cyclone Danas, which moved southwest across eastern Guangdong, possibly skirting past Guangzhou.
An active southwest monsoon to its south will generally affect the vicinity of the Pearl River Estuary on Thursday and Friday, the Observatory added, bringing torrential rain and squally thunderstorms over the region.
It will consider issuing the Strong Monsoon Signal depending on the local wind change.

Observatory issues T1 signal
Observatory issues T1 signal The observatory said it would decide whether to issue higher typhoon signals later on Wednesday to early Thursday. Graphic courtesy of the Hong Kong Observatory The Hong Kong Observatory issued the Standby Signal No. 1 at 8.40 am on Wednesday as Severe Typhoon Podul comes within about 800 kilometres of Hong Kong. Forecasters say the No.1 Signal will remain in force during the day today and will assess the need to issue a higher signal tonight to tomorrow morning. "Depending on the distance between Podul and the Pearl River Estuary, its intensity and the change in local winds, the Observatory will assess the need to issue the Strong Wind Signal, No. 3 tonight (13 August) to tomorrow morning (14 August)," a spokesman said in a statement. "Due to the fast moving speed of Podul, according to the present forecast track, Podul will make landfall again over the vicinity of southern Fujian to eastern Guangdong overnight." Podul is forecast to be closest to Hong Kong tomorrow morning. The observatory added that the subsiding air of the weather system will bring very hot weather with temperatures possibly rising to 35 degrees or above.

Observatory to issue T1 at 8.40 am as Pudol approaches
Observatory to issue T1 at 8.40 am as Pudol approaches The observatory said it would decide whether to issue higher typhoon signals later on Wednesday to early Thursday. Graphic courtesy of the Hong Kong Observatory The Hong Kong Observatory says it will issue the Standby Signal No. 1 at 8.40 am on Wednesday as Severe Typhoon Podul is expected to come within 800 kilometres of Hong Kong over the next few hours. Forecasters say a higher signal is possible later on. "Depending on the distance between Podul and the Pearl River Estuary, its intensity and the change in local winds, the Observatory will assess the need of issuing higher Tropical Cyclone Warning Signals later today to early tomorrow," a spokesman said in a statement. The observatory added that the subsiding air of the weather system will bring very hot weather over Guangdong on Wednesday, with showers to affect the region later in the day. Podul is expected to make landfall over the vicinity of eastern Guangdong to southern Fujian on Thursday, bringing heavy squally showers and thunderstorms to Hong Kong.

Drainage Services Dept buys three more pumping robots
Drainage Services Dept buys three more pumping robots Each 'mobile powerful pumping robot' can pump up to 800 cubic metres of water per hour. Photo: RTHK The Drainage Services Department (DSD) said on Tuesday that it has purchased three extra pumping robots, costing about HK$3 million in total, to help cope with the increasing frequency of extreme weather events in Hong Kong. Torrential rains have struck the city in recent weeks, prompting the observatory to issue four black rainstorm warnings within just eight days. The department already has three 'mobile powerful pumping robots,' all of which were deployed last week to address severe flooding incidents at locations including Queen Mary Hospital, an underground tunnel near Tai Po Station and a car park in Tseung Kwan O. Officials said once the robots were deployed, most floods were resolved within one to two hours. Each robot can pump 800 cubic metres of water per hour, equivalent to one-third of the volume of a standard-sized swimming pool. They can operate continuously for eight hours and are designed to cope with complex terrain such as stairs and slopes. When asked how the department decides which locations get priority for the robots, senior engineer Leo Chan said it is hard to pick individual places due to the unpredictability of flooding locations. 'There is great uncertainty in rainstorm events and we are not able to predict where the flooding incident is going to be,' he said. 'So we are going to place the robots strategically in our bases. Our goal is to get to the flooding locations as soon as possible once we receive the service call.' The robots do have limitations, such as only being able to handle floodwaters up to 60 centimetres deep, Chan said. To deal with rapidly rising water levels, the department deploys another model of pumping robot, which is smaller but can operate on both land and water, he added. Chan said more than 30 of the department's staff have been trained to operate water pumping robots and there are plans to arrange training for more employees.
