Elsa's arrival tomorrow is nothing to olaf about (OK, OK, we'll let it go), NWS says: We could see "major rainfall flooding," enough to force evacuations and rescues, "especially in urban areas."
Rivers could overflow their banks, streams and ditches could turn into "dangerous rivers" and you don't want to get near any underpasses. Roads could also become rivers; parking lots lakes. Areas right on the coast south of Boston could see winds strong enough to knock down trees and rip siding right off. There's even a chance of a tornado - although that may be more of an issue in the western part of the state. Power outages? Of course.
So get ready to flee quickly, especially if you're in a flood-prone area, NWS advises. And:
If you are a visitor, know the name of the county in which you are located and where it is relative to current watches and warnings. If staying at a hotel, ask the management staff about their onsite disaster plan.
The one saving grace: The storm won't be here long - NWS says it should blow in Friday morning, stick around for a few hours, then depart for the Maritimes.
