Cold Advisory for Newborn Livestock
The Cold Advisory for Newborn Livestock (CANL) system was created by the National Weather Service Glasgow office, Dr. Larry Kalkstein at the University of Miami and Dr. Katrina Frank at the University of Delaware. Dr. Kalkstein is one of the leading researchers on weather effects on humans (biometeorology), and Dr. Frank has a background in animal sciences and climatology (bio-climatologist). The system is designed to indicate weather conditions dangerous to newborn livestock. The criteria for this system were derived from interviews with Montana ranchers and from published scientific research on animal health.
We are targeting those livestock that are less than 24-hours old because these animals are least able to regulate their body temperature and therefore most susceptible to the cold. Also, after several hours, producers may have had a chance to get to the animal, dry it off, and provide shelter as needed.
NWS offices participating in the experimental system for the winter of 2009-2010 include:
