A special weather alert has been issued for much of southern BC, including the entire Okanagan Valley.
Environment Canada is forecasting torrential rains that could drop upwards of 25 milimetres of rain from Penticton to Vernon.
The report states that a slow moving upper low is tracking through the southern interior today and bands of showers will continue through Wednesday evening.
Between 10-20mm is expected by late this evening, however thunderstorms may result in higher rainfall totals for some areas. There is still some uncertainty over the exact location where these higher locations may occur.
Due to the recent snowmelt, this could further compound flooding issues and high water levels in some areas.
This sudden precipitation has also affected the Coquihalla Highway, which saw a few inches of snow fall overnight.
