WCSD Students to Make Up Future Snow Days Online

North Valleys High School was on a temporary precautionary code yellow lockdown for less than hour on Friday after it was first issued by school officials. 

School officials first issued the alert around 1:30 p.m. due to a possible threat to the school. 

Police say they conducted a thorough investigation before the lockdown was ultimately lifted after 2:15 p.m. 

This is a developing story.
