This weekend’s Singapore Grand Prix is under threat as a haze continues to engulf the country, with the Pollutant Standards Index (PSI) continuing to rise.
The PSI has hit the ‘very unhealthy’ bandwidth of pollution, with a year high of 222 on Monday, with the 24-hour PSI being estimated to be between 130 and 161, according to Singapore’s National Environment Agency (NEA).
Several local outdoor events have already been cancelled as a result of the haze, including a charity race for cancer scheduled for Sunday, while several air flights being diverted due to low visibility.
“The haze situation could further deteriorate should the current unfavourable winds blow in denser haze from Sumatra,” said the NEA in a statement.
“Thundery showers are forecast for Singapore in the pre-dawn and early morning hours, but this may only bring a brief temporary respite to the hazy conditions.
“The 24-hour PSI for the next 24 hours is expected to be in the mid to high sections of the unhealthy range, and may enter the low section of the Very Unhealthy range if denser haze from Sumatra is blown in.”
