Short answer
Before winter rains, clear yard and gutter drains, make sure the sewer cleanout cap is in place, check exposed pipes and hose bibs, and know where your main shutoff is. Heavy storms can overload old sewer laterals, so slow drains before the rain are worth getting checked.

Drains and cleanouts
Missing cleanout caps let rainwater into sewer lines and cause backups.
Sewer laterals
Old clay laterals with root intrusion back up during storms.
