The National Weather Service (NWS) has issued a wave of freeze warnings, freeze watches, and frost advisories spanning six states, affecting thousands of residents.

There is a concern that this sudden drop in temperature could damage crops, vegetation, and outdoor water pipes.

The NWS has urged residents in the affected areas to take precautionary measures Tuesday and through Wednesday, as “frost and freeze conditions could kill crops, other sensitive vegetation, and possibly damage unprotected outdoor plumbing."

Residents across the Midwest, Northeast, Mid-Atlantic, Southwest, Mountain West, and select regions on the West Coast are under active freeze warnings.

Counties in the Midwest can expect to see subfreezing temperatures ranging from 23 to 28 F until Wednesday morning. The NWS has urged residents to “drain in-ground sprinkler systems and cover above-ground pipes.”

Areas affected include: Kansas, Southwest Nebraska, Edwards, Kiowa, Pawnee, Stafford, Clark, Ford, Meade and Seward counties.

Many Northeast counties will see subfreezing temperatures in the upper 20s to low 30s until Wednesday morning, with areas near the immediate shores of Lake Ontario remaining slightly warmer.

Areas affected include: Niagara County, Orleans County, Monroe County, Wayne County, Northern Cayuga County, Northern Erie County, Genesee County, Northern Fairfield, Northern Middlesex, Northern New Haven, Northern New London Counties, Western Bergen and Western Passaic Counties, Northern Westchester and Rockland Counties

Locations in the Mid-Atlantic can expect to see subfreezing temperatures ranging from 30 to 33 this morning, which could kill sensitive outdoor plants if they’re left uncovered.

Areas affected include: Putnam County, Orange County, Mercer, Western Monmouth, Middlesex, Atlantic, Cumberland, Ocean, Salem, Southeastern/Northwestern Burlington Counties, Kent County, Queen Anne’s County, Camden, Gloucester, Delaware, Cecil County, Southeast Harford County, and Lower Bucks Counties.West Coast
