Understanding Cold Weather Alerts
Cold Weather Advisory: Be Aware
A cold weather advisory signifies seasonably cold temperatures or wind chill values that could be uncomfortable but aren’t dangerously cold. It’s crucial to dress appropriately and protect exposed skin when going outdoors during such advisories.
Extreme Cold Warning: Take Action!
An extreme cold warning indicates dangerously cold temperatures or wind chills that are currently occurring or expected. Individuals in affected areas should minimize outdoor activities. If venturing outside is necessary, ensure to layer clothing, cover all exposed skin, and inform someone about your whereabouts, updating them upon reaching your destination.
