Heavy rainfall battered southwestern Manitoba Tuesday night and and into Wednesday, with some areas seeing flash-flooding for the second time since the weekend.

Parts of Brandon saw flash-flooding in streets and power outages. About 80 mm of rain was reported overnight.

Homeowners in Brandon are now cleaning up following the overnight rain storm that also brought strong winds and hail.

A number of properties suffered water damage because the city's sewer system was simply overwhelmed, according to Brandon officials.

"We had heavy rains on the weekend...a torrential downpour last night. These kind of extreme weather events on top of each other has just overwhelmed the storm sewer system," said Brandon Mayor Shari Decter Hirst.

The city is advising homeowners to contact their insurance providers, which might not pay for all of the flood costs.

Officials say they will apply to the province for disaster assistance money to help flood victims but caution there is no guarantee the funding will be approved.

The city advised residents to make sure sewer grates on their street are free from debris and to make sure their sump pumps are working, in case more rain falls.

Reston sees flash-flooding for second time since weekend

Reston received even more precipitation, seeing upwards of 100 mm between 6 and 9 p.m. on June 25.

The RM closed several roads and a section of Highway 2 remained a concern Wednesday.

Reston had earlier experienced flash-flooding on the weekend.

Resident Sheila Campbell says people were just cleaning up their flooded basements when they were hit again on Tuesday.

She said homeowners in the town of 600 had piled up their soggy couches and freezers on the curb after the first deluge, only to watch the rising water carry everything away when the second rainstorm tore through the area.

"We had a terrible thunderstorm go through here with lots of high winds. There's trees down," Campbell said Wednesday.

Water from Tuesday's storm began flowing into about 50 homes, that had just been pumped dry from the weekend storm.

"It was overflowing and splashing into the house. It was making its way into the deck and thankfully we had 30 or 40 great volunteers," said resident Dallas Williamson.

Dozens of people came out to help pump out water and sandbag homes. Some residents were also put on evacuation alert.

The province issued an advisory about more overland flood warnings and high water advisories for parts of Manitoba on Wednesday afternoon for areas in the northwest, Interlake and southwest regions, including Reston and low-lying lands around Dauphin.
