Another powerful winter storm could move through the Ottawa region as early as late Wednesday, Environment Canada warned Monday.

A low-pressure system is expected to form over Texas on Christmas Day, then head northeast.

It has the potential for "significant snowfall accumulations," according to a notice posted on the weather agency's website.

CBC climatologist Ian Black said the storm looks to be another "Colorado low," similar to Friday's storm that dumped more than 40 centimetres of snow throughout the region, starting on Friday.

Black said Monday he doesn't expect that much snow to fall this time around, but that he'll be keeping a close eye on the storm's development.

"Present indications suggest that the snow would start in the southwest during the day on Boxing Day, and then spread eastward to reach Eastern Ontario later in the evening. In addition, gusty northeast winds would result in local blowing snow reducing visibilities," Environment Canada said on its website. "Conditions should improve from west to east on Thursday."

The storm hasn't yet developed and its track may change. Therefore, the weather agency said Monday that it was still too early to predict precipitation amounts.
