My First Special Weather Statement

So I got the opportunity to put out my very first special weather statement the other day.  These are used to notify the public of the potential for severe weather when there’s some significant uncertainty in the weather.  They explain a little about what’s going on, and what the current expectations of the forecaster are, and what it is that could be different than the current thinking.  After the fact, it turns out that my SWS was pretty much bang on, which makes me smile.

Special Weather Statement issued for…

City of Winnipeg
Steinback – St. Adolphe – Dominion City – Vita – Richer
Dugald – Beausejour – Grand Beach
Morden – Winkler – Altona – Emerson – Morris
Bissett – Nopiming Provincial Park – Pine Falls
Whiteshell – Lac du Bonnet – Pinawa
Sprague – Northwest Angle Provincial Forest

Heavy rainfall is possible for the southern Red River Valley and southeast Mantioba through this evening and Saturday.  Locally severe thunderstorms may produce in excess of 50 mm this afternoon and this evening.  Convection will give way to an intense low pressure system that will move across southern Manitoba overnight and Saturday brining widespread rain with embedded thunderstorms.  Total rainfall accumulations are uncertain, but currently a further 30-60 mm of rain through Saturday seems most likely.  However, the potential exists that some areas may see the possibility of recieveing in excess of 90 mm.  As more information becomes available about the track and the intensity of the incoming low pressure sysstem rainfall accumulations in the local forecasts will be updated.
