Strong El Niño Expected to Influence North American Winter Weather

Why it matters locally: While the immediate impact on New Hampshire's winter weather isn't directly outlined, strong El Niño patterns can indirectly influence broader atmospheric conditions that affect New England's temperature and precipitation, potentially leading to variations from typical winter forecasts.

Climatologists forecast a strong phase of the El Niño climate pattern, commonly referred to as a 'Super El Niño,' to significantly influence winter weather across North America. This pattern typically intensifies during the winter months, altering both precipitation and temperature across the region. Researchers predict this strong El Niño will increase the probability of winter precipitation throughout the Southern United States. The pattern also impacts hurricane season activity. Forecasters have identified several states as susceptible to considerable snowfall and extreme weather occurrences during the upcoming winter season.
