Heavy rain swamps Winnipeg.. again..
For the second time in five days, thunderstorms brought heavy rainfall to Winnipeg, with particularly heavy amounts over the west end. The heavy rain swamped drainage systems, and led to extensive street flooding and waterlogged properties in west Winnipeg (see photo here of Buckle Drive in Charleswood). Last evening, heavy downpours began around 6:15 pm in Charleswood, and continued through 8 pm. At my site, I recorded 42 mm during the evening downpour (peak rainfall intensity 155 mm/hr) , on top of the 20 mm that fell with showers earlier in the day, for a daily rainfall of over 60 mm. Winnipeg airport recorded 45 mm yesterday, with 26 mm falling during the evening downpour. This comes on the heels of a heavy downpour last Thursday that dumped over 50 mm at my site (35 mm at the airport) Scattered showers will persist today across southern MB, but amounts will be light. Thankfully, a trend to drier and warmer weather is forecast over southern MB by the end of the weekend into next week.

Well our snow chance east of Lake Winnipeg got killed. Winds probably won't be strong enough. But we did get a good dumping of rain yesterday. If you look at Regina's low for tonight, that low is cold enough to support some snow or wet snow. Christmas in July anyone?
ReplyDeleteAnd Daniel, you got my name right. :)
Many MB, ND, and Mn locations reported extreme pcpn amts though the data this am indicates the result was haphazard. .1 to 150mm
ReplyDeleteTwo sites that provide links to or display the data are http://www.crh.noaa.gov/fgf/climate/climate.php (link on my name) and
The WunderMap Interactive Radar & Weather Stations (Weather Underground) on your site ROBS OBS>Current Temperatures>WINNIPEG AREA MAP (at the bottom select DISPLAY OPTIONS "Precipitation" .
Bet the rain was slightly heavier west of your station. I'm sure it was at least 75mm here for the day. I'm guessing based on how much the water level rose in my pool. I'm in Westdale backing on to the Perimeter.
ReplyDeleteTotal rainfall here in east Charleswood was 66.4 mm up to 9 AM this morning. Need to get back to building my ark.
ReplyDeleteSo....
ReplyDeleteIf July averages below normal (which is probably will) then that will make it 8 months in a row of below normal months!
Ok.....so who wants to make it 9 months for a record!
I mean we come this far...might as well go for the record!
Steinbach got about 25mm.
ReplyDeleteNow Winnipeg knows all about excessive rainfall. Steinbach and the RRV learned about that in late June!
we had to drain some water from our pool. It was level with the patio and the wind was lapping at the patio shore and there were waves...lol...so that's just under 3 inches (75mm) in Oak Bluff...sorry I mean Lac Bluff
ReplyDeleteRain gauge network from the city confirms 50-70 mm rainfall totals yesterday in the west end of the city, with the maximum of 70 mm at the lift station at Wilkes and the Perimeter. So the 65 mm at my site looks reasonable. Rainfall was about 50-60 mm in St James with amounts dropping off sharply in the southeast to 30 mm or so.
ReplyDeleteNote that there was also heavy rainfall over the whiteshell last night with 70 - 85 mm from Pinawa through Falcon Lake areas.
It is so chilly with that brisk northwest wind today it almost feels like.....shall I say September!!!
ReplyDeleteRainfall totals are now posted by Environment Canada under there Special weather statements!!
ReplyDeleteThanks Daniel P for the EC Bulletin info The WunderMap Interactive only displays the current days totals
ReplyDeleteNOAA s bulletin last night reported over 150mm of rain in the Fergus Falls area but it appears to be anecdotal as the most I saw today was 80mm
Some weak lake effect rain bands off Lake Manitoba coming into Winnipeg this evening giving us a cool drizzly evening.. almost October like. 850 temps are +2C to +3C over the southern lakes with lake temperatures at 18C giving 15-16C temperature differentials.. easily enough to support lake effect. It's even colder at 850 mb in The Pas this evening at an unseasonably cold -3C. Even so, it's still +9c at the surface, with light rain falling. At this time of year, there's too much low level heat input from the surface and lakes to get snowflurries at the surface. Still, you don't want to be talking about lake effect in July.
ReplyDeleteArea of rain over Interlake will spread south into Winnipeg and SE MB overnight. Rain may be enhanced by narrower bands of lake effect in NW flow off Lake Winnipeg and Lake Manitoba as 850 cold core moves over southern MB tonight. Perhaps another 5-10 mm of rain under more persistent bands overnight into Thursday.
Your blog keeps getting better and better! Your older articles are not as good as newer ones you have a lot more creativity and originality now keep it up!
ReplyDeleteWhat a great resource!
ReplyDeleteBad weather with thunder caused flooding in some parts of Winnipeg. This happened exactly a month after my Californian trip where I spent a week from June 6 to 15. If I want to avoid severe and extreme summer weather here in Manitoba, I should spent summer in California, where is nice and warm.
ReplyDeleteRob, that's a good idea to go there in summer because severe weather (thunder, rain or tornado) are rare in California. However, it's still hot and there are wildfires due to Sta Ana Winds in the fall and lot of rain during winter.
