A winter storm warning has been upgraded to a blizzard warning for parts of northwestern Ohio, starting at 7 a.m. today, as heavy snow and gusty northeastern winds are expected.

The National Weather Service issued the blizzard warning on Tuesday for counties in the expected direct path of the storm, including Hancock, Seneca, Hardin and Wyandot. The warning is set to expire at 7 a.m. Thursday.

Accumulation of snow in those counties could reach between 6 and 10 inches, while gusts of wind are expected to reach as high as 40 mph, the weather service said late Tuesday. Officials said blowing snow will make for "dangerous travel" conditions this afternoon and tonight, with visibility near zero at times.
