Smith County commissioners voted to extend the county-wide burn ban until further action.
Determining the need for a burn ban depends on several variables, including the Keetch-Byram Drought Index and the number of grassfires difficult to contain. The drought index measures moisture in vegetation that could act as fuel for fires.
The index ranges from zero to 800, zero being under water and 800 being extremely arid, combustible conditions. Once the index reaches 600, fire officials begin to look at other variables and consider taking action.
County Judge Joel Baker said he implemented the index reached 678 Tuesday and that no significant rain was in the forecast.
