Extreme Cold Warning vs Watch and Cold Weather Advisory

• Extreme Cold Warning: Take Action! An Extreme Cold Warning is issued when dangerously cold air temperatures or wind chill values are expected or occurring. If you are in an area with an Extreme Cold Warning, avoid going outside. If you have to go outside, dress in layers, cover exposed skin, and make sure at least one other person knows your whereabouts. Update them when you arrive safely at your destination.
• Extreme Cold Watch: Be Prepared. An Extreme Cold Watch is issued when dangerously cold air temperatures or wind chill values are possible. As with a Warning, adjust your plans to avoid being outside during the coldest parts of the day. Make sure your car has at least half a tank of gas, and update your winter survival kit.
• Cold Weather Advisory: Be Aware. A Cold Weather Advisory is issued when seasonably cold air temperatures or wind chill values, but not extremely cold values, are expected or occurring. Be sure you and your loved ones dress appropriately and cover exposed skin when venturing outdoors.

Freeze Watch vs Warning and Frost Advisory

• Freeze Warning: Take Action! A Freeze Warning is issued when temperatures are forecasted to go below 32°F for a long period of time. This temperature threshold kills some types of commercial crops and residential plants, while temperatures below 28°F for an extended period of time can kill most types of commercial crops and residential plants.
• Freeze Watch: Be Prepared. A Freeze Watch is issued when there is a potential for significant, widespread freezing temperatures within the next 24-36 hours. A Freeze Watch is issued in the autumn until the end of the growing season and in the spring at the start of the growing season.
• Frost Advisory: Be Aware. A Frost Advisory means areas of frost are expected or occurring, posing a threat to sensitive vegetation.
