The National Weather Service is warning of flash floods and “very heavy rainfall” as the remnants of what was Hurricane Ida pass through the region Wednesday night into Thursday.

“While the axis of heaviest rain is uncertain, the potential exists for a narrow swath of very significant flooding,” the service said.

The service predicts that many areas will receive 2 to 4 inches of rain, while some places could receive up to 6 inches. There could be flash flooding, along with flooding from rivers and streams.

The service has issued a flash flood watch for all of Massachusetts, Connecticut, and Rhode Island, from Wednesday night through Thursday.

“Excessive rainfall will increase the risk for urban and poor drainage flooding,” the service said.

Here’s what other local forecasters are saying about the potential flooding:

David Epstein: ‘Move stuff that might get wet and check the sump pumps’

Jeremy Reiner, 7News: ‘Rain tapers by midday Thursday’

Mike Wankum, WCVB: ‘2-4″ of rain seems likely and there is a possibility of a few spots getting a half FOOT of rain’

Sarah Wroblewski, WBZ: ‘Majority will see about 2-4″ but some of our hi-res models have a subtle shift south & pushing totals over 6″ in spots’
