A Freeze Watch is in effect for all of central and parts of southwestern Alabama from 01:00 to 08:00 LT on March 21, 2025.
The cold temperatures and freeze warnings are due to a strong cold front that moved through the Tennessee Valley on March 19, 2025, bringing showers, thunderstorms, and a significant temperature drop.
Residents are advised to take necessary precautions to protect sensitive vegetation from the dropping temperatures. Tender plants should be covered or moved to sheltered areas to prevent damage from the cold.
To minimize the risk of freezing and potential pipe bursts, exposed plumbing should be wrapped, drained, or left to drip slowly. Allowing a small, steady flow of water can help prevent pipes from freezing, especially during prolonged cold spells.
For those with in-ground sprinkler systems, proper winterization is essential. Draining the system and covering above-ground pipes can help protect them from freezing temperatures and potential damage.
