A Level 3 alert is triggered when severe weather is occurring and average temperatures are not expected to rise above 2°C for the next few days.
Today's alert indicates a 99% chance of ice or snow in the West Midlands between now and Thursday (1 March), with widespread frost and significant wind chill. 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 such as heart trouble or respiratory problems.
"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 may feel isolated or scared to venture out. Please make sure they have access to warm food and drinks, have sufficient stocks of any medicines they may be on, and are managing to heat their homes adequately."
