France's civil aviation authority says about 20 percent of flights at Paris' main airport are to be canceled Wednesday because of expected snowfall.

The group asked airlines to cancel some flights at Charles de Gaulle airport between 7 a.m. and 5 p.m. local time.

Airlines generally try to spare long-haul flights in such cases.

Snow fell in the French capital Tuesday, which is uncommon. It quickly turned into slush.
