Environment Canada has issued a "Weather Advisory" for Humboldt, Wynyard, Wadena, Lanigan and Foam Lake.

An unstable air-mass will lead to shower and thunderstorm development Tuesday afternoon. As these showers and thunderstorms develop, conditions will be favourable for funnel clouds.

Emergency Preparedness Meteorologist John-Paul Cragg dispels the myth that it needs to be sweltering hot before funnel clouds can form.

"Funnel clouds don't have to develop in hot weather, all you need is a weak thunderstorm and good rotation in the atmosphere. The updraft of the thunderstorm takes that rotation and stretches it out, it spins really fast and then you see what results is a funnel cloud."

Cragg goes on to say the thunderstorm activity we could see in the region is expected to be minor in nature including the funnels.

"They would form a weak land spout tornado," he explained if they do touch the ground. "Which could be dangerous for residents, it's not the same as a really strong tornado that could do lots of damage but it's still a danger for residents."

Reports of spotted funnel clouds have been received from Colonsay to St. Brieux and areas in between Tuesday morning.

"Funnel clouds, you should keep an eye but don't be overly about them as most of them don't touch the ground," Cragg reassured.

Thunderstorms will be prevalent over the next three or four days, Cragg expects it to be a cool, wet week in the Humboldt region. It could be a week before temperatures steadily increase back in to the 20 degree mark.
