Camden, NJ – Residents across four South Jersey counties should prepare for a chilly overnight period as temperatures fall toward 35 degrees, bringing the possibility of frost that could damage or kill sensitive outdoor plants early Wednesday morning.
According to the National Weather Service in Mount Holly, a Frost Advisory is in effect from 1 a.m. until 9 a.m. Wednesday, November 11, for Camden, Gloucester, Salem and Cumberland counties.
The advisory includes communities such as Cherry Hill, Camden, Glassboro, Pennsville and Millville, along with surrounding areas across southwestern New Jersey near the Philadelphia metropolitan region.
Temperatures Near 35 Degrees Could Damage Plants Forecasters expect overnight temperatures to drop as low as 35 degrees, cold enough for frost to form on exposed surfaces and vegetation under favorable conditions.
Although temperatures may remain above freezing at standard measuring heights, frost can still develop on plants and other surfaces that cool more rapidly overnight.
The greatest concern is for sensitive outdoor vegetation, including tender flowers, garden plants and other cold sensitive landscaping.
The National Weather Service warns that vulnerable plants may be killed if left uncovered during the advisory period.
What South Jersey Residents Should Do Tonight Residents are encouraged to protect tender plants before heading to bed Tuesday night.
Moving potted plants indoors, covering vulnerable vegetation with frost cloth or lightweight fabric, and checking exposed garden areas can help reduce potential damage.
The advisory is scheduled to expire at 9 a.m. Wednesday as temperatures rise and the threat of frost diminishes.
Residents throughout Camden, Gloucester, Salem and Cumberland counties should monitor local forecasts for any changes in overnight temperatures.
