Nor’easter timeline and estimated snow totals [updated]

The coming nor’easter will progress from fluffier snow to heavy, wet snow. That precipitation mixed with strong winds could equate to a new set of issues for people — including more power outages.

“I’m not as concerned about ice build up, but heavy, wet snow accumulating on tree limbs that were already strained during the last storm, that might be on the edge; so you do have the potential for some more power outages,” said NBC10 First Alert Weather chief meteorologist Glenn “Hurricane” Schwartz.

Flooding can also be a concern should more heavy rainfall, especially when mixed with snow already laying on the ground from past storms.

“I’m sorry. I wish I didn’t have to relay it,” Hurricane said of the forecast. “I know people have had a rough time and some worse than rough and there is no joy in putting out a forecast like this.”

Thursday morning “could be a mess in one way or another” as the worst of the storm moves out leaving the effects in its wake, Hurricane says. Here’s how the storm is expected to shake out.
