Clear Vista School, AB

Thunderstorms are developing in east - central Alberta. Some of these thunderstorms may become severe this afternoon, and produce strong wind gusts, large hail, and heavy rain.

###

Severe thunderstorm watches are issued when atmospheric conditions are favourable for the development of thunderstorms that could produce one or more of the following: large hail, damaging winds, torrential rainfall.

Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to ABstorm@ec.gc.ca or tweet reports using #ABStorm.

Conditions are favourable for funnel clouds to develop near a line from Lacombe to Drayton Valley to Three Hills. This line will move slowly to the north and east this afternoon.

###

These types of funnel clouds are generated by weak rotation under rapidly growing clouds or weak thunderstorms. This weak rotation is normally not a danger near the ground. However, there is a chance that this rotation could intensify and become a weak landspout tornado.

If conditions become more favourable for the development of landspout tornadoes, watches and warnings will be issued by Environment Canada.

Landspout tornadoes do not usually cause significant damage but can still be dangerous. They can be strong enough to topple trees, damage roofs or toss debris short distances.
