A strong El Niño may be developing, with potential effects including storms, heatwaves, and changes to weather patterns. The impact of El Niño on global temperatures and regional weather is expected to be significant, although the specifics of what it may bring to different areas, such as the US, are still being considered. The World Meteorological Organization has confirmed that a strong El Niño is approaching, but the exact nature and consequences of this event are still being assessed.
