( CNN ) -- Instead of presents , there might be IOUs under some Christmas trees in Colorado on Sunday . This week 's snow storm has delayed the delivery of some 50,000 UPS packages into the Denver area , CNN affiliate KUSA reported , citing a company spokeswoman . `` We know it 's Christmas . We apologize for the delay , but we ca n't control the weather , '' Natalie Godwin said . `` As soon as we can , we 're going to get all of those packages delivered . '' Hundreds of people waited in line Saturday outside of the UPS building in Commerce City , hoping to pick up their packages , KUSA said . A winter weather system blasted broad swaths of the West and Midwest this week , dumping heavy snow . `` This makes no sense . They get paid . It snows in Colorado . That 's what it does here . So how are you in the business that you ca n't deliver what you say ? '' Jacqueline Camack , a frustrated customer , told KUSA . UPS has said it planned to make more than 120 million deliveries this week , its busiest of the year .
A company spokesman apologized for the delay . A winter ice storm covered broad swaths of the West and Midwest this morning . ` ` This makes no sense , '' says a frustrated customer .
