The snow emergency that has closed schools, businesses and government buildings throughout Erie County as flakes continue to fall on feet already on the ground hasn't slowed the workload for area first responders.

As lake effect snow pummels the northwest corner of the Commonwealth, the Pennsylvania State Police has handled over 400 calls in the past 24 hours. Governor Josh Shapiro (D) said troopers are working alongside the Pennsylvania National Guard.

The local disaster emergency order, Erie County Commissioner Brenton Davis said, will not be lifted so state resources are still available.

The National Weather Service in Cleveland's lake-effect snow warning is scheduled to expire Tuesday at 7 p.m. What to know:
