Forecasters Project Strong El Niño Event

Why it matters locally: A strong El Niño event could lead to a warmer and drier winter in Pennsylvania, potentially affecting agricultural yields, energy consumption, and increasing the risk of brush fires. The Pennsylvania Department of Environmental Protection may need to monitor water levels and air quality more closely during such an event.

Forecasters project a developing El Niño event will register among the most intense recorded since 1950. The National Oceanic and Atmospheric Administration (NOAA) began tracking these phenomena in 1950. El Niño involves a warming of the surface waters in the central and eastern tropical Pacific Ocean. This warming influences atmospheric circulation, impacting weather patterns across various regions worldwide.
