Can yard signs handle heavy rain and snow?

Most yard signs handle rain and snow well because the common materials are waterproof and won't absorb moisture. The one to watch in deep cold is PVC foam board.

• Corrugated plastic: waterproof and reliable through rain and snow.
• Aluminum: won't absorb moisture and handles harsh weather.
• PVC foam board: resists water but can turn brittle in prolonged freezing temperatures.
• Winter pick: corrugated plastic or aluminum are the safest for harsh conditions.
