Another flood, another different location.
A hall at Marina Bay Sands (MBS) exhibition centre partially flooded around noon on Tuesday.
Exhibitors for Singapore International Water Week were at the area.
An MBS spokesperson on Tuesday said, "At approximately 12:05pm today, a small area of Hall F was affected by an overflow of rainwater. Our teams promptly provided assistance to the event organizer and any affected exhibitors."
She said the area was cordoned off and cleaning completed.
MBS suspects the source of the overflow "is a drainage issue due to heavy rains in the morning".
She said investigations into the incident are being made to prevent a similar occurrence in the future.
This is simply a neat coincidence. Perhaps, it was a mee siam guy who conjured a 'reverse chili and onion' incantation to bring forth the heavy downpour as a sideshow for the 'Singapore International Water Week' exhibition.
After the exhibition, participants will likely heap praises to the sky on the smear of shit on sole of shoe for the ability to control the weather at the snap of his fingers.

National water agency PUB will also carry out new drainage improvement projects at 36 locations around Singapore as part of long-term efforts to improve flood protection.

SINGAPORE: National water agency PUB has stepped up efforts to prepare for the upcoming Northeast Monsoon season.
According to the Meteorological Services Singapore (MSS), the rainfall this season is expected to be slightly above average compared to previous years.
Singapore is in the midst of the inter-monsoon season which is why heavy rain warnings and flash floods have been a common sight in various parts of the island over the past few weeks.
This could continue with the approaching Northeast Monsoon season in mid-November.
On average, there are usually 19 rainy days each in November and December, and 15 in January, according to the MSS. The numbers are expected to be slightly higher this season.
To prepare for this monsoon season and minimise the occurrences of flash floods, PUB has intensified inspections on some 100 construction sites around the island to check for drainage obstructions.
It has also replaced about 6,000 scupper holes drain inlets at flood prone areas with an improved design of Drop Inlet Chambers (DICs). Scupper holes are found on the side of the road, next to kerbs.
The modified DICs will have vertical gratings that will provide an additional opening to allow rainwater to be drained from the roads when the main horizontal gratings are partially blocked by leaves or other debris.
PUB has also been distributing flood advisories to about 500 residential units and shop-houses in flood-prone areas.
These monsoon preparations are on top of current measures to minimise and respond quickly to flash floods. These include real-time monitoring of water levels in drains and canals with its water level sensors and CCTVs.
Chew Men Leong, chief executive of PUB, said: "Despite our best efforts, I think it's not possible for us to eliminate flash floods.
"When there are flash floods, what we can do is to ensure that information flows to the public as quickly as possible through our multiple channels, through social media and also through the more traditional media like radio and (TV) broadcast.
"Through that, the community can be alerted to potential flash floods and incidents, and they should, of course, be prepared as much as they can to mitigate its impact. This will include avoiding the area where the flash flood has occurred."
As part of long-term efforts to improve flood protection, PUB will also carry out new drainage improvement projects at 36 locations around Singapore.
The Sungei Pandan Kechil canal is one of the 36 drainages to be identified for improvement works.
In September this year, heavy rain caused the canal to overflow and flood a section of the Ayer Rajah Expressway (AYE), resulting in the closure of the expressway for about 40 minutes.
The canal will be widened by about four metres and construction is expected to start in the first half of 2015.
In the meantime, PUB said it has enlarged the inlet and outlet points of waste-water pipes at AYE to improve the flow of water.
Tan Nguan Sen, director of catchment and waterways department at PUB, said careful planning is required in order to prevent disruptions.
"A lot of these projects are carried out in very developed areas… where you have major roads, and buildings next to canals. The challenge is how do you carry out the work within these constraints and how do you carry out the necessary road diversions to prevent disruptions to traffic," said Mr Tan.
The new projects include improvements to the Tampines Canal from Upper Serangoon Road to Sungei Serangoon, and the Pioneer sector outlet drain.
These are on top of PUB's ongoing drainage projects at 176 locations, including eight major canals.
Other projects include the Stamford Detention Tank, located near the junction of Tyersall Avenue and Tyersall Road. The undergound detention tank will be completed by 2016.
Upon completion, the detention tank will temporarily hold excess storm water from the drains along Holland Road, which is upstream of the Stamford Canal catchment.
After the rain subsides, the water will be pumped back into the drains for discharge into Marina Reservoir.
The tank has a storage capacity of 38,000 cubic metres or 15 Olympic-sized pools.
Besides the detention tank, PUB will be constructing the Stamford Diversion Canal to divert storm water from the upstream section of the Stamford Canal catchment to the Singapore River.
The work will be carried out in phases, with the first tender to be called in the last quarter of this year, and another in the first quarter of next year.
Work on the entire diversion canal is expected to be completed by 2017.
Also starting next year are drainage upgrading works at Alexandra Canal Subsidiary Drain between Tiong Bahru Road and Havelock Road, and at Siglap Canal between East Coast Expressway (ECP) and the sea.

National water agency PUB put out a warning about the floods on their Twitter page.
The waters subsided in half an hour. By 5 pm, the road was once more passable to traffic.
The National Environment Agency had issued a heavy rain warning earlier in the day, at around 3 pm, cautioning that moderate to heavy thundery showers would hit many areas of Singapore.
