Four states are already on the map for significant snow this winter, and the pattern behind it is only getting stronger. Forecasters expect El Nino to build into a Super El Nino by the end of the year, the kind of setup that has historically buried the Sierra Nevada and the mountain Southwest in above-average snowfall. For drivers, the warning has arrived six months early, which is exactly the point.
What a Super El Nino Is

The El Nino weather pattern shows up when sea surface temperatures in the central and eastern tropical Pacific run warmer than average. In a Super El Nino, that warm anomaly exceeds two degrees Celsius. Researchers at the Columbia Climate School say the early warning signs are already in place, with subsurface heat across the equatorial Pacific beginning to rise toward the surface.
For U.S. winters that pattern historically tilts the odds a specific way: milder across the northern tier, wetter across the South. The strong El Nino winter of 1997-98 landed as one of the warmest and wettest on record.
The States Bracing for Snow
Milder does not mean drier where it counts for drivers. The latest predictions single out four states for heavy rain and significant snow this winter: California in the Sierra Nevada, New York, Vermont and New Hampshire. meanwhile puts its highest confidence on above-normal precipitation across the Gulf States and parts of the Southeast to Mid-Atlantic, and gives the strengthening El Nino an 81 percent chance of reaching very strong intensity by the end of the year.
Translated to the road, that is a wet Sierra with deep winter snow over Donner Pass and the ski corridors, another loaded winter for the Northeast on the back of last season’s cold one, and repeated rounds of rain and cold fronts across southern states where winter driving experience runs thin. These are the corridors where winter snow warning headlines will stack up once the season turns, and where an early forecast is worth acting on rather than reading.
There is a snow map too. NOAA’s own analysis of snowfall in El Nino winters shows exactly where the pattern delivers, in inches: more snow than average across the Sierra Nevada and the mountains of the Southwest, from Utah and Colorado through New Mexico and Arizona, and less across the northern tier from the Pacific Northwest through the Great Lakes. For drivers, that is the map that matters.
For the winter ahead there is no official snowfall forecast map, because no agency issues one at seasonal range. Until the first storms line up, the way to track where the snow potential sits is through overall precipitation, and NOAA’s seasonal outlook for January through March shows the moisture leaning above normal in a broad arc across the southern tier. Where that surplus falls on high, cold ground, it falls white.

Why August Is the Month to Get Ready
Winter gear pricing runs opposite to demand. Tire shops and online retailers clear winter stock and run their quietest promotions in late summer, chains that sell out by the first November storm sit on shelves now, and installers who will be booked solid in October can take an appointment this week. Waiting for the first forecast snowflake means paying peak price for whatever is left, alongside everyone else who waited.
The car itself can wait until closer to the season, but not past it. Book the pre-winter checkup for October: battery, coolant, wipers and brakes, before the first freeze finds whichever one of them was on its way out.
What Belongs on the List
Winter tires first if your winter includes real snow: the compound stays flexible below roughly 45 degrees, which is what shortens stopping distances, and no all-season fully substitutes for that in the Sierra or northern New England. Chains second, sized to your tires and practiced once in the driveway, because Sierra chain controls do not care whether you have ever installed a set. Then the trunk kit: scraper, shovel, traction boards or sand, jumper cables or a jump pack, blanket, headlamp.

Skills Are Gear Too
The cheapest upgrade is the one between the seats. Braking in a straight line before a curve, easing off the brakes on ice instead of stabbing them, and looking where you want the car to go are habits that can be learned in a parking lot and sharpened in a day. For drivers heading into a serious snow state, a winter driving course such as the dedicated snow-and-ice schools that run each season in Colorado and New Hampshire compresses years of trial and error into a weekend. One day of instruction in December costs less than one insurance deductible in January.
