A freeze watch was released by the National Weather Service on Sunday at 4:48 p.m. valid for Tuesday between 1 a.m. and 9 a.m. for Manhattan, the Bronx, Staten Island and Brooklyn as well as Westchester, Suffolk and Nassau counties.
The weather service comments, “Sub-freezing temperatures as low as 30 degrees possible.”
“Frost and freeze conditions could kill crops and other sensitive vegetation,” states the weather service. “Take steps now to protect tender plants from the cold.”
What to do if there is a freeze watch or warning
Freeze warnings are issued from May to October (but can be extended if necessary), when low temperatures are expected to be 29-32 degrees. If there is a potential for temperatures to fall into these thresholds, a freeze watch may be issued a few days ahead of time.
According to the weather service, if a freeze warning or watch is issued for your area, there is little you can do to protect plants. If you can move your sensitive plants inside, do so because the freeze will likely kill them, depending on the severity of conditions.
