Transportation Secretary Sean Duffy says a new software update prevented a third radar outage over the last two weeks at New Jersey's busy Newark airport when a telecommunications line failed again over the weekend.

Considering over 70% of the roads in the U.S. are located in snowy regions, having real-time weather alert updates can help make logistics more efficient and safe, because it allows fleet management systems to timely reroute vehicles to keep the drivers safe and away from icy roads.

The blackout included losing radar for about 90 seconds at Newark Terminal Radar Approach Control at 3:55 a.m. local time, a source with knowledge of the incident tells CNN.

Transportation Secretary Sean Duffy plans to reduce the number of flights in and out of Newark Liberty International Airport for the "next several weeks."
