The forest and land fires in and around West Sumatra have filled the province's air with haze causing visibility to decline to only 2,000 to 3,000 meters and affecting the activity of Minangkabau airport in the provincial capital of Padang.
The ideal visibility for airports to operate with is 10,000 meters.
'Reports from a number of regencies suggest that the haze has become thicker,' said Budi Samiadji from the Padang Meteorology, Climatology and Geophysics Agency (BMKG) as quoted by tempo.co on Friday.
He expressed hope that visibility in the area would soon get back to normal as the potential for rain in the province is high in the coming days.
Albert, a staff member at the BMKG's Global Atmosphere Watch (IGAW) in Bukit Kototabang, said that the air quality was declining, not only due to the fires in West Sumatra but also those in Jambi and South Sumatra.
'We anticipate a possible further drop in air quality, but there is chance of rain in West Sumatra. Hopefully, the rain might clear the haze,' he added. (bbn)
