LONDON, ONT. -- A tornado warning issued by Environment Canada for areas in southwestern Ontario Tuesday morning was sent out in error.

There are currently no warnings issued across southwestern Ontario. 

Around 8:40 a.m. Environment Canada issued the warning for widespread areas including London-Middlesex, Chatham-Kent, Watford-Pinery Park, Eastern Lambton County, Elgin County, Huron County, Oxford County, and Perth County. 

It is unclear how the error occurred as warnings are typically issued when a tornado is imminent.

Soon after the warning was issued it was rescinded.

There is a 30 per cent change of thunderstorms overnight and a 60 per cent chance of thunderstorms Thursday for London-Middlesex.

The forecast for Tuesday is 23 C and mainly sunny and as of 9 a.m. there was no activity on local weather radars.

Some took to social media to voice their concern over the false alarm.

Storm chaser David Piano said on Twitter that these kind of errors could make for a potentially dangerous situation.

Piano tells CTV News London, "I couldn't believe it and I thought that couldn't be right."

The Ingersoll, Ont. resident is concerned that next time people may not trust the warning.

"A huge portion of the population is warned about the worst warning there could be...people may not take it seriously next time."

The same concern was echoed by Western University's Northern Tornadoes Project.

They issued a statement that read, in part, "We hope that any critical gaps in the alerting system are promptly addressed so that all Canadians have full confidence in the warnings that they receive."
