Drought index is a measure of what?

Explanation:
A drought index reflects how dry the environment is by measuring the water content in the soil. Soil moisture represents the available water for plants and surface fuels, and it is determined by the balance of precipitation, evaporation, and drainage over time. This makes soil water content a direct indicator of drought conditions. Wind speed doesn’t indicate moisture, rainfall amount shows past precipitation but not how much remains in the ground, and fire intensity depends on many factors beyond soil moisture.
