A thick cloud of smoke pours from forest fires on the Indonesian island of Sumatra. Forest fires are common in Indonesia during the hot, dry months of the dry season, which runs from June to September. Hot, dry weather and winds blowing from the southwest help fires explode in Indonesias forests, and such conditions probably fed the fires seen outlined in red in this image. The winds are also responsible for blanketing parts of Malaysia with smoke. In this image, a white plume of smoke snakes north and east from the fires, moving inland over northern Malaysia. Not only does the dense haze decrease visibility, posing a traffic hazard for both air and ground travel, but the smoke could cause serious health problems.

The Moderate Resolution Imaging Spectroradiometer (MODIS) onboard NASAs Terra satellite acquired this image in the morning of June 25, 2005. By afternoon, the fires had grown to the point that the narrow Strait of Malacca that separates Malaysia from Sumatra was barely visible. Unfortunately, clouds also partially obscured the view of the region.

II. Fire Weather and Fire Danger Monitoring and Early Warning
Regional Fire Weather
The Regional South East Asia Fire Danger Rating System (SEA FDRS) is a joint effort between the Canadian Forest Service (CFS) and the Malaysian Meteorological Service (MMS), supported by the Canadian International Development Agency (CIDA). Daily updated SEA Fire Danger Rating can be downloaded on the following website of MMS, and background information on the project can be found at the SEA FDRS Project website.
Latest example of a SEA FDRS product:
The Fire Weather Index (FWI) values shown on the map are numerical ratings of fire intensity.
Information from the Initial Spread Index (ISI) and Build Up Index (BUI) is combined to provide a numerical rating of fire intensity.
This index is used to indicate the difficulty of fire control based on the head fire intensity and fire fighting capability.
Information on the Indonesian Fire Danger Rating System (Indonesian FDRS) is provided by the Indonesian Bureau of Meteorology and Geophysics (BMG) in Jakarta. The site provides information for fire managers working to prevent and control vegetation fires and smoke in Indonesia.

The GFMC displays selected and daily updated global and Asia-Pacific Experimental Climate Prediction Center (ECPC) Fire Weather Forecasts. These examples allow a quicklook and provide daily and weekly total forecasts and forecasted monthly totals. For background information refer to the ECPC products description page.
