Fears have been raised that the Singapore Grand Prix could become affected by smoke and smog as wildfires rage in neighbouring Indonesia.
AFP reports that illegal wildfires on the islands of Borneo and Sumatra are the worst since 2015 and have rendered the air quality "very unhealthy" in Malaysia, which also owns land on Borneo.
Over 1,500 schools have reportedly closed in Malaysia, with the capital Kuala Lumpur, west of Borneo and approximately 225 miles to the north of the Singapore border, among the worst affected areas.
Flights have been cancelled in Indonesian Borneo, although Singapore is not suffering the same level of issues thus far.
A statement on the tourist board's website reads: "Singapore continues to warmly welcome our visitors but would like to advise that extra caution be taken during this period. We suggest that visitors access daily updates on the haze outlook and health advisories at www.haze.gov.sg and take the necessary precautions in their travel plans."
F1 has arrived in the country this week and the weather could make on of the season's most physically demanding races all the more difficult.
The Singapore's tourist board executive director of sports, Jean Ng, told Today: "Various Singapore government agencies have been working closely with [the] race organiser to ensure the delivery of the best race and entertainment experience possible while keeping a watchful eye on the health and well-being of everyone involved."
