The strong El Niño is expected to bring significant weather impacts, including heavy rainfall and mountain snow in California, which could lead to flooding and mudslides. Southern states may experience cooler and wetter conditions, with the potential for severe storms and freezing precipitation. Northern states, on the other hand, are likely to see reduced snowfall and milder temperatures. The Northeast could face heavy rain and snow if storms along the southern tier move northeast. These conditions could disrupt travel, agriculture, and daily life, particularly in areas prone to flooding or severe weather.
