Yellow Watch - Severe Thunderstorm

Conditions are favourable for the development of severe thunderstorms that may be capable of producing heavy rain. Hail and strong wind gusts are also possible.

Funnel clouds are also possible today.

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/or 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.

Treat any funnel cloud sighting seriously. Should a funnel cloud develop nearby, prepare to take shelter. These funnel clouds usually appear with little or no warning.

###

Damage to roofs, fences, branches or soft shelters is possible.

Heavy rain can cause flash flooding and significant reductions to visibility.

Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to ABstorm@ec.gc.ca, call 1-800-239-0484 or post reports on social media using #ABStorm.
