The sudden plunge into extreme cold is set to hit states from Arkansas to New York, with temperatures expected to plummet overnight Monday into Tuesday morning. The NWS has issued freeze warnings across several regions, urging communities to take immediate action to protect vulnerable vegetation, infrastructure, and people.
Freeze Warnings Impact Key States
According to the NWS, freeze warnings are in effect for large swaths of the U.S., spanning Arkansas, Louisiana, Mississippi, Texas, Virginia, North and South Carolina, Alabama, and parts of New Jersey and New York. These areas are bracing for unusually low temperatures that could reach as low as 22°F in some places, well below freezing.
In particular, Southeast Arkansas, Northeast Louisiana, and central Mississippi are expected to see the sharpest temperature drops. These regions have been issued two separate freeze warnings due to the severity of the cold, with temperatures in some areas dropping to as low as 22°F by early Tuesday. Similarly, parts of North and Central Texas could experience temperatures of 25°F, with sub-freezing conditions expected to persist through the night.
While the freezing temperatures may not reach extreme lows in all affected areas, the consequences of such cold are serious. The NWS has emphasised that subfreezing temperatures can harm sensitive plants, particularly crops, which are vulnerable to frost. Additionally, outdoor plumbing is at risk of freezing, potentially leading to burst pipes and costly repairs.
Potential Hazards and Precautions
The NWS has issued several advisories to help mitigate the risks posed by the cold snap. One key warning involves the protection of outdoor water pipes, which are at risk of freezing and bursting in these subfreezing conditions. According to the NWS, homeowners should take steps to insulate pipes, drain outdoor plumbing systems, and allow water to drip slowly to prevent damage. Those with sprinkler systems are advised to drain them as well to protect their investments.
In addition to the risk of frozen pipes, the cold weather can be dangerous for vulnerable populations, including young children, the elderly, and the homeless. The NWS cautioned that exposure to wind chills as low as 20°F could lead to hypothermia or frostbite if proper precautions are not taken. Communities are advised to check on their elderly neighbours and ensure children are appropriately dressed for the cold.
The cold weather is also expected to exacerbate hazardous conditions in coastal regions, where high winds could lead to dangerous conditions for small craft. For example, a lake wind advisory has been issued for areas along Lake Moultrie, with winds reaching up to 25 knots, causing waves that could endanger boats.
As the freeze warnings remain in place until Tuesday morning, the NWS continues to urge residents in affected areas to take immediate action to safeguard against the cold. Protective measures, such as wrapping vulnerable pipes, covering plants, and ensuring pets have a warm shelter, are essential. Authorities also advise checking local forecasts regularly for any updates, as rapidly changing conditions could make it difficult to anticipate how the weather will develop.
