Two converging storms that will move up the East Coast could produce the biggest March storm the Capital Region has seen in more than a decade.

The Capital Region and much of New England are under a winter storm warning that will start just after midnight Tuesday and last until 8 p.m. Wednesday. The forecast is for between 10 to 18 inches of snow.

Snow is expected to start for the Albany area about 5 a.m. Tuesday and will be at its heaviest until Tuesday evening.

The last significant snow in March measured at 10.7 inches during a 2005 storm.

Systems are moving across the Ohio Valley and developing in the south and will create a nor'easter that will bring heavy snow and high winds to the Northeast.

"Some of the computer models have come together and ... it definitely looks like some pretty heavy snow that's going to be accumulating," said Brian Frugis with the National Weather Service in Albany.

New York City, Long Island and the coastal areas of Connecticut have been issued a blizzard watch as winds could reach past 40 mph and there will be little visibility.

"This would certainly be the biggest snowstorm of the 2017 winter season in New York City," said Faye Barthold, a weather service meteorologist based on Long Island.

Gov. Andrew Cuomo announced Sunday that the New York State Emergency Operations Center will be activated Monday evening, with stockpiles of sandbags, generators and pumps ready.

Temperatures will also be cold, with a high of 28 Tuesday and a low of 18.

A significant storm would bring the seasonal snow total up to normal for the Capital Region.

Currently, our area is 10.5 inches below average snowfall for a winter season. The region hasn't seen significant snowfall since a storm hit just before Valentine's Day.
