El Niño watch issued by NOAA's Climate Prediction Center
Climate scientists estimate the warm weather pattern could begin to develop as early as May.
www.cbsnews.comHere’s the latest high-level overview of El Niño as of now.
-
Core concept: El Niño is the warm phase of the El Niño-Southern Oscillation (ENSO) cycle. During El Niño, sea surface temperatures in the central and eastern Pacific Ocean are warmer than average, which can alter global weather patterns. This basic definition comes from NOAA’s ENSO resources and widely used climate literature. [cite ]
-
Recent status and expectations: NOAA and other climate agencies monitor ENSO conditions and issue outlooks when El Niño is developing or ongoing. In recent cycles, forecasts have varied from weak to strong El Niño scenarios, with corresponding shifts in expected rainfall and temperature patterns across different regions. For example, past updates have described potential for wetter conditions in parts of the southern United States and drier or warmer conditions in others, depending on the strength of El Niño.

Impacts to watch:
- United States: El Niño often brings wetter-than-average winters to the southern tier and increased storm activity in the southern and eastern parts, with potential drought relief or continued challenges in other regions depending on how the pattern evolves. [cite ]
- Global: Wetter conditions can occur in parts of the Americas, while other regions may experience drought and shifts in monsoon patterns. The exact impacts depend on the Niño strength and regional climate interactions. [cite ]
- Atlantic hurricane season: El Niño tends to suppress Atlantic hurricane activity and can influence Pacific hurricane activity, with implications for seasonal risk planning. [cite ]

How to stay updated:
- Check NOAA’s ENSO pages and Climate Prediction Center advisories for the latest official status and outlooks.
- Look for statements about ENSO watch/alert status and any updates on sea-surface temperatures and atmospheric indicators measured in the Niño3.4 region.
If you’d like, I can pull the most current official ENSO update summaries and summarize the latest forecast numbers (e.g., Niño3.4 SST anomalies, probability of El Niño development this year, and expected regional impacts) with direct citations.
