High streamflow advisory issued for Tulameen River
Global News
'Freezing levels are currently forecast to rise between 1,000 and 1,500 metres, resulting in rain and above-freezing temperatures at mid-to-low elevations.’
A high streamflow advisory has been issued for the Tulameen River in B.C.’s Southern Interior.
The province’s River Forecast Centre issued the advisory on Thursday, at noon, stating that an incoming Pacific frontal system this weekend will bring rain at lower areas and snow at higher elevations.
“Freezing levels are currently forecast to rise between 1,000 and 1,500 metres, resulting in rain and above-freezing temperatures at mid-to-low elevations,” said the Ministry of Forests.
“Current weather and hydrologic forecasts indicate a portion of this precipitation could fall as rain within the headwaters of the Tulameen River, translating into the potential for higher river flows especially within the smaller, upstream parts of this watershed.”
The ministry said river impacts will depend on how much precipitation falls as rain, how much of the watershed receives rain, and how high freezing levels climb on Saturday.
The ministry also said forecasts indicate the potential for increased flows beginning Saturday and peaking into Sunday to Monday.
“At this point, forecasts for the Tulameen at Princeton are lower than peaks experienced at the end of November and early December,” said the ministry.
“This pulse of water will cause the downstream Similkameen River to rise Sunday into Monday.”
