A Frost Advisory is in effect for 9 counties and cities in south central and southeast Virginia as temperatures fall as low as 33 degrees early Tuesday.
The National Weather Service in Wakefield says the advisory runs from 1 AM to 8 AM EST Tuesday, Nov. 10.
Where the advisory is in effect
The advisory covers Brunswick, Dinwiddie, Prince George, Greensville, Sussex, Surry, Southampton and Isle of Wight counties, plus the city of Suffolk.
It includes the independent cities of Hopewell and Petersburg, as well as Emporia, Franklin, Lawrenceville and Windsor.
Frost could harm sensitive outdoor vegetation, and plants left uncovered may be killed.
Patchy frost beyond the advisory
NWS Wakefield says frost is less widespread outside the advisory area, but patchy frost is also possible.
The forecast map shows lows around 36 to 37 across much of inland southern Virginia, including Richmond. Coastal areas stay far milder, with Norfolk near 47.
The same advisory also covers four northeast North Carolina counties: Northampton, Hertford, Gates and Bertie.
Highs Monday were mainly in the lower to mid 60s, according to NWS Wakefield, with a slight warming trend by Tuesday afternoon.
The Weather Service first flagged patchy frost well inland for early Tuesday in its weekend forecast. The advisory now covers a wider area of southern and southeast Virginia.
Frost can form on grass, car windshields and exposed plants even when air temperatures stay a few degrees above freezing.
Rain and cooler air later this week
Dry and seasonable weather continues through midweek, with sunny skies and temperatures in the 60s.
A chance of rain returns Thursday and Friday, and NWS Wakefield says much cooler conditions are on the way by late in the week.
What to do
Take steps now to protect tender plants from the cold. Cover them or bring them indoors before dark.
