Are you ready for spring? Meteorological spring officially begins March 1st, with the spring equinox happening on March 20th.
The extended forecast is looking chilly for at least the first full week of March, with the chance for a few frosty mornings. With the growing season starting in South Carolina, and the potential for freeze or frost, the National Weather Service will start issuing watching and warnings again.
If these are issues for your area, what can you expect? The criteria for a frost advisory is 80-percent, or higher probability, that scattered to widespread frost will occur.
A freeze Watch would be issued when temperatures are expected to drop to freezing levels (32 degrees) or lower within 12-48 hours. As the potential for freezing temperatures gets closer and the confidence grows, this watch would be upgraded to a freeze warning. This means 80-percent probability that temperatures will drop to freezing or below freezing within 12-24 hours.
The average last freeze across most of the Lowcountry happens in March, except for downtown Charleston with the average last frost in early February. The Charleston airport, also our observation station, normally has the last freeze in early March.
If temperatures are expected to drop near freezing in your area, make sure you take proper precautions with your pets, plants and pipes. If temperatures drop below freezing for an extended period, it is best to slightly run your water to prevent freezing pipes. Cover plants to prevent any damage done by freezing temperatures.
A good rule of thumb: if it is too cold for you, it is too cold for your pets. Bring them inside.
Count on Storm Team 2 to keep you updated on any watches/warnings issued in the Lowcountry.
