Could a powerful El Niño bring a wetter wnter to the Borderland?

EL PASO, Texas (KVIA) — Thousands of miles away, the Pacific Ocean is heating up, and the effects could reach all the way to the Borderland this winter.

The phenomenon, known as El Niño, could become one of the strongest on record since 1950, raising hopes for increased precipitation in a region struggling with years of drought. Elephant Butte Reservoir, a critical source of water for southern New Mexico, sits at just around 5% capacity.

El Niño develops when Pacific trade winds weaken, allowing warm ocean water to spread eastward. That heat influences atmospheric circulation, shifting the jet stream and potentially steering more Pacific storms across the southern United States, including El Paso and surrounding communities.

Historical records offer some encouraging signs. Since 1950, El Paso has experienced nine strong El Niño winters, and seven brought above-normal precipitation. The winter of 1982 stands out, delivering an extraordinary 35 inches of snow.

However, El Niño does not guarantee a wet winter. The 2023 El Niño brought dry conditions to the region, highlighting how other weather patterns can influence local outcomes.

Even a stormy winter would not erase years of drought overnight, and replenishing reservoirs will take sustained precipitation and runoff.

For now, El Niño offers a reason to watch the forecast closely. Residents can prepare for the possibility of a wetter, stormier winter while staying informed with KVIA's StormTRACK Weather team.
