The Meteorological Service of Singapore reports on 18 February 2000 for the South East Asian region: “The northeast monsoon over the region is moderating gradually. Isolated localised showers with thunderstorms over Kalimantan and Sumatra. The region still remains relatively free of smoke haze.” Forecasts of winds and surface pressure are also available.

Fig. 2.-7. Fire Weather Index (FWI) forecast for tomorrow (left), next week (center) and the predicted FWI anomaly for next month (right) for the Western Pacific and the Pacific Ocean. The daily forecast refers to 12:00 hrs noon UTC (Greenwich) time; the weekly total forecast and the monthly forecasted anomaly refer to 00:00 hrs UTC, which is local noon at dateline (180° longitude). Forecast time is 12:00 hrs noon UTC (Greenwich) corresponding to local evening time in mainland and insular SE Asia (updated: 18 February 2000).

The ASEAN Fire Weather Information System (ASFWIS) is a co-operation between ASEAN and the Canadian Forest Service. It provides maps describing the current fire weather situation in South East Asia. This system is based upon the Canadian Forest Fire Danger Rating System (CFFDRS) (for further infomation to the CFFDRS refer to ASFWIS). Studies have shown that the CFFDRS is applicable outside of Canada. Currently it is also used in a modified form in New Zealand (see References). In New Zealand the Fire Weather Indices Fine Fuel Moisture Code (FFMC) and the Initial Spread Index (ISI) represent the fire danger in the scrublands. The Duff Moisture Code (DMC) is also applicable in South East Asia, because it potentially describes the moisture state of the upper peat layers in peat and peat swamp forests. All three parameters may serve as a suitable indicator of forest fire danger in South East Asia.
According to the ASFWIS for 17 February 2000 these parameters show various fire weather conditions over South East Asia.

Summary: Although the current fire weather conditions do under normal conditions not favour extensive land clearing by fire or escaping wildfires in Indonesia, the consequences of the large wildfires of 1997-98 must been taken into consideration. These fires had caused extensive degradation of primary and secondary forests along with the spreading of “alang-alang” (Imperata cylindrica) grasslands. These grasslands facilitate the spread of uncontrolled fires over large areas.
