Fiona is set to make history this weekend.
Winds in P.E.I.'s capital city Charlottetown are expected to gust to 140 kilometres per hour with the arrival of the storm.
Just how fast is that exactly?
Cars typically travel down the highway at a speed of 110 kilometres per hour, and a professional baseball pitcher's fastball travels at about 152 kilometres per hour.
So - if a piece of debris gets picked up, it could be travelling at a speed somewhere in between a car and a fastball.
With winds that high, your best bet is to stay indoors.
What about waves?
Some waves over the eastern portion of the Gulf of St. Lawrence could be higher than 12 metres.
How high is that?
That's about the size of a school bus on its side, or 12 full-length hockey sticks stacked on top of each other.
In terms of width, Fiona is expected to be about 1,500 km at its widest diametre when it makes landfall. That's roughly the distance between Halifax, Nova Scotia and Ottawam Ontario - or the size of about 24,000 hockey rinks.
Thankfully we have four teams spread out across the region just to cover it.
