KUALA LUMPUR: The worsening haze has forced the postponement of next week's 100PLUS National Junior Development Programme (NJDP) Junior Series Grand Final due to health concerns for young golfers.

The four-day tournament, scheduled for Oct 27-30 at Seri Selangor Golf Club, has been put on hold as unhealthy air continues to blanket the Klang Valley, with no new dates announced.

As of 2pm on Tuesday, Petaling Jaya, Shah Alam and Johan Setia in Selangor recorded unhealthy Air Pollutant Index (API) readings of 170.

Earlier at 9am, 30 locations nationwide registered unhealthy air quality, up from 27 on Monday, with Johan Setia and Batu Muda in Kuala Lumpur recording the highest readings of 172.
