- CPC
- NOAA’s Climate Prediction Center, which sets the El Niño and La Niña status (Watch, Advisory) once a month.
- ONI
- The Oceanic Niño Index: how much warmer (+) or cooler (−) than normal the surface of the central Pacific Ocean was over three months. The letters are the months, so JJA is June, July and August. El Niño conditions are +0.5 °C or warmer.
- NWS
- The National Weather Service, which issues the weather watches, warnings and advisories for your area.
- D0–D4
- The U.S. Drought Monitor’s levels: D0 abnormally dry, D1 moderate drought, D2 severe, D3 extreme and D4 exceptional drought. Each percentage is the share of the state at that level or worse.
