The Standardized Precipitation Index (SPI) distribution map is significant because it turns the SPI into a continuous spatial visualisation, revealing the location, extent, and severity of drought across Southeast Asia or Malaysia, even in areas with sparse rain gauge coverage, thereby enabling more timely and spatially informed drought decision-making. 

This report is significant as a recurring early-warning tool: by tracking precipitation anomalies across short-, medium-, and long-term timescales each month, it gives authorities a consistent, standardized basis for spotting emerging drought or flood risk early enough to act, regardless of what any single month's data shows.
