Sub-freezing temperatures as low as 23 are possible, according to officials. Frost and freeze conditions could kill crops, other sensitive vegetation and possibly damage unprotected outdoor plumbing. This will effectively end the growing season.
Offcials advised to take steps to protect tender plants from the cold.
