Rainfall warning overnight tonight (Monday)
8/11/2008 at 10:55 PM
I see that just before 10 PM Environment Canada put us under a rainfall warning where they say we could get from 30 to 60 mm. Looking at radar, a bit of a system has developed just to the North and West and is so slow it barely appears to be moving... hence why it could dump so much rain on anyone underneath it.
The official text...
---------------
30 to 60 mm of rain expected tonight with locally higher amounts along the Manitoba escarpment.
A slow moving trough of low pressure has brought an area of rain to southern Manitoba. Embedded thunderstorms will give heavy rainfall at times tonight. This system is moving slower than earlier expected and has stalled over western Manitoba. As a result the heaviest rainfall amounts are now expected to be west of the Red River Valley over the higher terrain along the Manitoba escarpment. Rainfall of 20 to 40 mm is expected tonight in many areas with higher amounts of 50 to 70 mm along the Manitoba escarpment from Morden to Treherne to Gladstone to Ste Rose Du Lac to Swan River. The rainfall will taper off by Tuesday morning.
