The deadline to sign up for health insurance through New York's open marketplace was extended by five days, through Dec. 20, authorities said.

The deadline to enroll or renew a plan, which was originally today, was pushed back to accommodate for last month's "extreme winter weather," the NY State of Health said in a statement.

Western New York and other parts of the state were covered in several feet of snow, making it unsafe for people to attend in-person enrollment activities, according to the NY State of Health.

Nearly half of all people who enrolled in the open marketplace last year worked with someone in person.
