Join us today to talk about all the weather that we’ve missed over the last 3 months and dive into the details to the Ottawa area tornados.

t’s been 3 long months since the last episode and over 4 months since we’ve been able to tie down Daniel and drag him to the microphone.

Welcome to episode #8 of Canada Talks Weather on October 17th, 2018!

Welcome

Thank you for joining us for this episode of Canada Talks Weather – the (now) bi-weekly podcast where we talk about all things weather coast to coast across Canada.

Daniel and Jerry talk about our hiatus from Canada Talks Weather and what our plans are moving forward.  So where have you been Daniel?

Our plan is to shoot for podcasts every other week this fall and winter.  Building a podcast and arranging guests can be hard work and instead of rushing out an episode, we’d like to put more effort into each effort at a manageable pace.

Some weather events over the last several months….

-Fire Season across Canada

-heavy precipitation events.

-The EF4 tornado moved through the Rural Municipality of Alonsa on Friday Aug.3rd killing a 77-year-old man and leaving a trail of destroyed homes and cottages.

-Cold outbreak and Winter early in Western Canada – heat in S. Ontario

-Hurricanes Florence and Michael in the USA
