ROCHESTER, N.Y. (WHEC) — Do you hit a pothole, or almost hit one every day on your way into work?

45 of the 66 days we’ve had so far of winter, or about two out of three days, have had below-freezing temperatures in the morning, and above-freezing temperatures during the afternoon.

That means there’s a freeze and a thaw all within a 24 hour period. 

Potholes form when water gets into cracks in the pavement while temperatures are above freezing, then freezes when temperatures drop overnight, expanding the cracks in the pavement. 

The reason we get potholes is the constant expanding and contracting of water in the same place over and over. 

We have had above-average precipitation by about two inches this season, which is not helping the situation.  

It may seem like potholes are always on your route to work, school or where ever you are headed and that is because pavement cracks even more when cars are constantly driving over a weak patch.

And there’s more wet weather head our way.

To report a pothole that needs filling, call 1-800-POTHOLE.
