Forecasters say it's still difficult to say with certainty where exactly a Colorado low will head, but that there will be more moisture over southern Manitoba on Monday.
"We have access to a number of models that help us predict the weather and all the models are pointing towards a formation of a Colorado low. The tracks of this low are different from model to model," says Natalie Hasell, an Environment Canada (EC) Warning Preparedness Meteorologist.
"Some models are pointing towards it going through southern Minnesota and would therefore not affect us at all. Some are having it go through northern Minnesota and that would impact us and a couple of other models suggest it will go straight through the middle of Manitoba. So the difficulty here is that until we have more agreement we can't likely say which areas will be affected," Hasell says.
However, the most likely areas to receive a storm are the Red River Valley and the southeastern corner of the province. Due to the potential of a low from Alberta interacting with the Colorado low, more of the province might be affected by this combined system. It will be more central and reach northern Manitoba as opposed to southern.
"That could mean we have an extended time again of precipitation and strong winds. It could be 10 millimetres to 25 up to 50 millimetres or more of rain. It won't make it any easier for those who are in a state of emergency, that is going to be a problem for a lot of people," Hasell says.
"It hasn't been easy for anyone in Southern Manitoba over the last month and a half, unfortunately, it looks like that's going to continue to be a problem."
"We are expecting this system to maybe hit us late Sunday into Monday and the combination of systems extends that into Tuesday and Wednesday," Hasell says.
Chris Stammers from EC says that the good news is temperatures should stay well above the freezing mark. That means, at least, the rain will not be freezing on hydro lines causing more power problems for the province.
Preparation is key
Hasell says that if the recent Thanksgiving storm taught us anything it's that it is time to get prepared. "I would start with an emergency kit. One for your home and one for your car. A kit that not only has first aid material but what you would need for you and your family to be okay on your own for up to three days. That could be how long it takes for help to reach you," Hasell says.
If you are planning to travel in the next few days, stay flexible. "There are parts of the province where you won't have easy access to things. If you travel, you might get to where you want to go but you might not get back," Hasell says.
"If you don't have power, do you have what you need to be comfortable in your own home? Do you have medications for everyone? Do you have the food and water for everyone? If you have a newborn do you have what you need for them? You need to look at every member of your family and figure out what it is they need.
"People are still cleaning up from the last storm, so having another one coming so soon will certainly make things difficult for a lot of people.
"Whatever the case may be, the initial responsibility of being okay in cases of emergency lies with the individual of the household. So, the best thing that everyone can do is be better prepared," Hasell says.
Some tips include having access to batteries, and ways of charging your phone without power, as well as access to the forecast, to stay updated on what is coming. "All of the little things start to add up really quickly when you are in dire straights.
"It hasn't been easy for anyone in Southern Manitoba over the last month and a half, unfortunately, it looks like that's going to continue to be a problem," Hasell says.
