Seasonal flags are provisional, not operational advisories. 78 source-series flags change with an unfiltered history baseline.

06-09 / 2026 monthly satellite-and-gauge product, equal-weight mandal means, for the history since 1981. AP DES mandal gauges to 17 Oct 2026: −39.6% against the department's normal, area-weighted.

JAS 2026: 2.16 °C. Three-month index, not a mandal forecast. Film and ocean maps have separate snapshot dates.
Current NOAA advisorySOIL, STORAGE & CROPSPartly connected
Modelled soil moisture (NRSC, via APWRIMS) for 18 Oct 2026. Reservoir storage 44.5% of capacity at 19 Oct 2026, measured at the headworks. Not connected: crop, sown area, stage and canal delivery to fields. The crop-water lab uses reference coefficients and user-set assumptions.
NIC e-Panta contextSnapshot built 2026-10-19. Groundwater fetch receipt: 2026-10-19. Public portal check 2026-10-19: 3/3 sampled series matched. This does not verify every mandal.
Useful now
Briefings, historical comparison and selecting records for field verification. Groundwater flags are not crop-loss or drought declarations.
Baseline review required
Seasonal comparisons inherit model-history eligibility filters. 580 source-series comparisons change when unfiltered valid history is used. Departmental baseline approval and a versioned data/film refresh are required.
Operational release pending
Authorised feeds, official location IDs, validated thresholds, crop/supply joins, a named approving officer and an auditable action log. No allocation or farmer advisory is issued here.

VIIRS, 4 km, weekly, against the record since 1981; read per mandal for the Drought Watch's remote-sensing indicator. All vegetation, not cropland alone: the drought manual prefers 56–500 m NDVI/NDWI from the State Remote Sensing Centre or MNCFC.

1,746 stations; one recent reading per mandal beside our monthly series (its May value matches ours in 585 of 587). Mandal geography gives official outlines, LGD codes and constituencies. Pulled by a signed-in user, not by the weekly job. AWARE's own groundwater, dry spell, El Niño modules showed no advisories or alerts at the pull.
TerraClimateModelled climate / mm
Valid / reference period2025
Recorded fetchNot supplied
Annual reference context, not current telemetry. Rain minus actual ET excludes pumping and does not establish aquifer recharge.
Operational release gates
What must happen before official use.
No completion percentage: each gate needs its own evidence and acceptance.
Authorized source access
Pending acceptanceWritten source-use approval, a verified ingestion contract and retained refresh receipts. Public portal access alone does not confer operational authority.
Official administrative crosswalk
Pending acceptanceOfficial boundary polygons, district and mandal identifiers, and resolution of ambiguous or unmatched source series.
Approved methods & field checks
Pending acceptanceIndependent field corroboration, cohort-specific error limits and approval of the seasonal baseline. Model performance is not a certification.
Crop and supply evidence
Pending acceptanceAuthorized e-Panta / APAIMS crop aggregates (APWRIMS already holds crop-sown and crop-stress dashboards behind a login), crop stage, irrigated area, and the canal command-area map with delivery records. Gauge rainfall, soil moisture and reservoir storage are connected as dated context. No crop-loss or allocation claims yet.
Accountable review workflow
Pending acceptanceNamed departmental reviewers, action records, escalation rules, security review and service monitoring before dispatch.
AWARE acceptance
Pending acceptanceAgreed schema, access controls, test environment, error handling and approval. Current payloads are unreleased drafts.
