Manitoba flood fears rise once again with incoming heavy rain, storm threat

Manitoba is bracing for the risk of more flooding this week, thanks to another Colorado low that is set to impact the eastern Prairies with soaking rains and the threat for severe thunderstorms Thursday. Because of the incoming rain and flooding potential, an overland flood watch is in place for southern and central Manitoba, with 26 municipalities remaining under local states of emergency. More on the timing of the rain and potential for flooding and severe storms this week, below.

LATE WEEK: ANOTHER SOAKING, RISK OF SEVERE WEATHER FOR EASTERN PRAIRIES

Wednesday will start off with fair conditions, but showers will spill into southern Manitoba and northwestern Ontario through the afternoon and evening hours. Thursday will see the low push through with the heaviest rainfall, also bringing the threat for thunderstorms, potentially severe in some areas with locally higher rain totals.

There is still some uncertainty where the heaviest rain will fall, but areas stretching from east-central Saskatchewan and southern Manitoba, as well as northwestern Ontario, will need to be prepared for an additional 20-40 mm of rain and locally up to 60 mm.

The heavy rain isn't the only threat southern Manitoba and northwestern Ontario will be faced with on Thursday.

Strong to severe thunderstorms are possible for the aforementioned regions Thursday evening and overnight. Heavy rain could lead to more flooding in Manitoba, while strong winds and large hail are also possible. Heavy rain will also extend west across eastern and central Saskatchewan.

The Storm Prediction Center in the U.S. has placed parts of the Upper Midwest into an enhanced risk for severe weather, with a lesser threat reaching the border with southern Manitoba and northwestern Ontario.

However, the chance of severe storms reaching the Canadian side of the border will be quite conditional, depending on where the warm front sets up. It could either be met with elevated or surface-based instability. The result could either be a rainy day with embedded thunderstorms or a severe risk with rotating storm potential.

As the low continues to track north, precipitation on the north and western extent of the system is forecast to transition to snow Friday night into Saturday morning for northern Saskatchewan and Manitoba.

Because of this additional rainfall, an overland flood watch was issued on Monday for all of southern and central Manitoba.

According to the provincial news bulletin, Manitoba's hydrologic forecast centre will update its water level forecasts to determine the effect the rain will have on the areas already experiencing flooding.

Officials say the Red River flood of 2022 is already the sixth largest on record by volume. Only the 1997 and 2009 floods were larger.
