A Winter Weather Advisory remains in effect until 4 a.m. Wednesday for southern Maine and much of New Hampshire, with an additional inch of snow expected to bring storm totals to 3 to 5 inches. Southern New Hampshire could also see up to one-tenth of an inch of ice, creating slick conditions on roads and bridges.

Why it matters

The snow and ice accumulation could make driving hazardous, especially on secondary roads and elevated surfaces like bridges and overpasses. Drivers are advised to slow down, increase following distance, and check road conditions before heading out.

The details

Communities including Portland, South Portland, Biddeford and Saco in Maine, along with Manchester, Nashua, Concord and Portsmouth in New Hampshire, are reporting snow-packed secondary roads. Even minor ice accumulation may make untreated stretches of Interstate 95, Interstate 93 and Route 16 slippery through the early morning commute.
