A Level 3 alert is triggered when severe weather is occurring and average temperatures will not rise above 2°C for the next few days. It also indicates a 90% chance of ice or snow in the area. Night time temperatures of 0°C or below are forecast for at least the next week.
Councillor Paul Sweet, the City of Wolverhampton Council's Cabinet Member for Public Health and Wellbeing said: "When the mercury in the thermometer is plunging, it's important that people keep an eye on the weather forecast and plan the day around it.
"Icy weather can cause roads and pavements to become slippery and hazardous when travelling outside. People should take extra care when they are out and about, dress warmly and wear non-slip shoes to limit any falls.
"It is critical that people stay warm when they are indoors, particularly if they're aged 65 or over, or have long term health conditions.
"During colder temperatures the chance of heart attacks, respiratory diseases including flu and the risk of hypothermia increase, especially amongst those with underlying health conditions. Indirectly, a drop in the temperature can also affect mental health illnesses.
"Homes should be kept at a minimum of 18 degrees centigrade, and wearing lots of thin layers and eating hot food will help people stay warm.
"I'd also urge people to look out for friends and neighbours who may be vulnerable to the cold and make sure they have access to warm food and drinks and are managing to heat their homes adequately, and also check to see if they are okay as they may feel isolated or scared to venture out."
