414 mm against a normal of 574 mm · Deficient · 29 rainy days · 4 gauges

Last month: 184 mm against 122 mm.

Measured: AP DES mandal rain gauges via APWRIMS.

2nd driest of 13 years for this date (range 14 to 99%). A week earlier: 58%.

Modelled: NRSC VIC land-surface model via APWRIMS; plant-available water as a share of what the soil holds.

A count of stated tests, not a score. The soil model is driven by rainfall, so those two are not independent.

Crop vegetation, 17 Sep to 14 Oct 202633 · severely below normal

Weekly since 25 Jun; dashed lines at 40 and 60, the drought manual’s class limits. Cropland is about 89% of this mandal's land.

Satellite index: NOAA STAR VHP, 4 km weekly, weighted to cropland (ESA WorldCover 2021). Plant vigour against the same weeks in other years, not yield.

Rainfall vs normal−25%414 mm against 552 mm · Deficient. Table 3.1 (IMD): normal +19 to −19%, deficient −20 to −59%, large deficient −60 to −99%, no rain −100%. Measured: AP DES gauges via APWRIMS.
Longest dry spell6 wk3.2.1 B: consecutive weeks after the monsoon's due onset with under 50% of the week's normal; usually 4 weeks, 3 on light soils.
1 Jundashed line: half of normal11 Oct
SPI route (satellite)−0.49Near normal; would set Trigger 1 on its own route. 3.2.1 C: SPI below −1 is a deficit; below −1.5 sets Trigger 1 without a dry spell. CHIRPS v3 since 1981.
Trigger 1 set by a dry spell. Table 3.11: a dry spell sets Trigger 1. Without one, only large-deficient rainfall (or SPI below −1.5) does.
Step 2 · Trigger 2 · 3 of 3 indicatorsModerate
Remote sensing · VCI Severe31Table 3.4: VCI 60–100 normal, 40–60 moderate, 0–40 severe. NOAA STAR VHP, 4 km, last four weeks. Satellite index over all vegetation; coarser than the manual prefers.
Soil moisture · PASM Moderate55%Usual for the date 78%. This date read Severe in 3 of 12 earlier years. Table 3.6 (2020): PASM 76–100 no drought, 51–75 moderate, 0–50 severe. The State may recalibrate. Modelled: NRSC VIC at 30 cm via APWRIMS, four-week mean.
Hydrology · GWDI Normal−0.29Mild: 1.9 m below ground against a 1.1 m mean for the month, 12 years. Table 3.9: GWDI above −0.15 normal, to −0.30 mild, to −0.45 moderate, to −0.60 severe, below extreme. Measured: APWRIMS wells.
Agriculture · area sown n/a—Not published per mandal: the Agriculture department holds it. 3.2.3.1: sown area under 85% of normal is drought; 75% or less is severe.
3.3.1 Step 2: severe if two of three are severe and the third at least moderate; moderate if two are moderate or worse.
Step 3 · the State
Field verification due before harvest. 3.2.6: field checks in 10% of villages, about 5 sites per major crop; crop loss of 33% qualifies, over 50% for severe.
