Malaysians can expect a hazy and hot Hari Raya, with less rain in the coming days resulting in another wave of dry spell.

Malaysian Meteorological Department spokesperson Hisham Mohd Anip said the forecast was due to the emergence of three continuous typhoons elsewhere in the region - Neoguri, Rammasun and the current Typhoon Matmo.

The typhoon, Hisham is quoted by The Star as saying, would drag moisture from the air in the surrounding areas leading to the dry spell. The typhoons were not expected to directly affect Malaysia although the seas may be roiled by high waves.

He also blamed Sumatra in Indonesia for the hot weather as hotspots on the island had increased steadily since July 16.

As of 11am yesterday, unhealthy air quality readings were recorded in five areas, with the air over many more areas approaching the unhealthy level.

Port Klang, Kuala Selangor, Seberang Jaya, Seri Manjung and Kampung Air Putih  recorded unhealthy air pollution index, between 100 and 200. The Star reported that Port Klang had the highest air pollutant index at 139.

Other areas reported to have borderline bad air included Petaling Jaya (89), Shah Alam (98), Bakar Arang in Sungai Petani (91) and Tanjung Malim (90).

Visibility was reported to be poor in places such as Butterworth (3km), Petaling Jaya (2.5km), Subang (3.5km) and Bayan Lepas (4km).
