Normal with other precipitation-based drought indices.According EDDI results, driest month April. During 12-month seasonal period, only 5 months passed form no drought.According SPEI RDI values, normal achieved at all stations. Moderately severely conditions sometimes occur, extremely rarely seen. identified more duration than SPEI.According PCI HTC (based on temperature), RAI (precipitation-based), region dominated by drought. When viewed station-by-station basis, observed borders.
