The first severe thunderstorm watch of the year has been issued from Windsor up to Barrie. I don't know how to make a simple list of places under the watch, so I will just link EC's fancy new warning map.

Also note that places like Detroit are under a tornado watch.

What do you guys think of the new severe thunderstorm warning message format? Also, is there anyone near the severe thunderstorm warning that can record the message over the weather radio? Curious to see what it sounds like.

Sarnia - Petrolia - Western Lambton County

Severe thunderstorm warning for
Sarnia - Petrolia - Western Lambton County continued

At 3:20 PM EDT, meteorologists are tracking a line of severe thunderstorms in the Windsor area.

The storms will continue to move eastward and northeastward and are expected to reach a line from Goderich to Chatham to Point Pelee by 4:00 PM EDT.

Damaging winds, large hail, torrential dowpours, and frequent cloud to ground lightning are associated with these storms.

Emergency Management Ontario recommends that you take cover immediately, if threatening weather approaches.

Strong wind gusts and hail can damage property and cause injuries. Local downpours can cause flash floods.

Go indoors and move away from windows and skylights. Avoid areas of the building that could be affected by falling debris such as tree limbs. Stay on the lower floor of your home or building and if the storm is particularly severe go to the basement.

Avoid driving through water on roads. Even shallow fast moving water across a road can sweep a vehicle away.

Remember, severe thunderstorms can produce tornadoes.

In Canada, lightning kills up to 10 people every year. Remember, when thunder roars, go indoors.

Environment Canada continues to monitor the situation closely. Stay tuned to your local media or Weatheradio for further updates. If you would like to report severe weather, you can send an email to .

70 kmh wind gust here in Windsor. Actual blew off a piece of my roof fascia.

Weak little shelf approaching me in London. Just got off work not thinking it's worth driving north at this point to intercept. They don't look very strong at all.

Some word of a tube way up north of Shelburne. Some surface level rotation was detected there too.

We got skirted by a fantastic shelf cloud which passed over the city with a cell that went through Woolwich Township.

Lots of lightning and odd dark clouds here in Sutton and a bit of wind.

However a barn was ripped to shreds and moved across the road in Shelburne

So maybe the first real twister of the year already?
