Rainfall speeding up Kamloops area streamflows

The Thompson River is not considered at risk for major flooding this year.
May 22, 2013 - 4:28 PM

Between 10-40mm of rain has fallen across the region since yesterday morning with parts of the Fraser Canyon and Shuswap areas seeing the highest amount of precipitation. In Kamloops a new rainfall record was set as the airport measured 22mm of rain over a 24 hour period, nearly double the previous record of 10.1mm set in 1997. With that rainfall Kamloops has surpassed the average monthly rainfall of 24.4mm.

Though record rains have fallen no advisories have been issued for the Thompson River. As of this morning a high streamflow advisory for several Interior rivers and creeks remained in place due to heavy overnight rain though. Among the rivers under advisory are the Nicola, Salmon, Shuswap and Eagle rivers.

Rainfall warnings are still in place for today through tomorrow in the Fraser Canyon and Shuswap, both of which could see another 30mm fall by Thursday morning. The B.C. River Forecast Centre advises this could cause the rivers, which have risen rapidly over the past 12-16 hours, to increase even more rapidly.

Cooler temperatures over the weekend saw the Thompson River go from a peak of just over 7m last week to just under 6.5m by Tuesday morning. Rains the last two days have caused a slight rise in the river again but cooler temperatures continue to prevent snow packs from melting off too quickly, which could cause a quick rise of the river.

While not considered a high flood risk the Thompson River has flooded some areas, like the Rivers Trail at the east side of Riverside Park.
