Staffordshire snowball reports blocking police lines
Staffordshire Police has reported a four-fold increase in 999 calls, but say many are about snowballs being thrown at people.
The force said such calls could prevent genuine emergency callers from getting through to control room operators.
It has asked people to be patient when ringing due to high call volumes and to bear in mind that police officers also faced difficult driving conditions.
People are being advised not to travel unless necessary.
So far about 17cm (6.6in) of snow had fallen in east Staffordshire.
More than 130 schools were closed due to snow on Wednesday in North Staffordshire, Stoke-on-Trent, the Staffordshire Moorlands and Stafford and Newcastle-under-Lyme Borough Council areas.
Waste collections were suspended on Wednesday in the Staffordshire Moorlands area as crews were called in for snow clearing and gritting duty.
Staffordshire County Council said some Moorlands areas had 16.5cm (6.5in) of drifting snow overnight.
