Update - Latest graph from above the Babine shows a downward trend. See 6pm graph attached below.
The temperature in the mountain ranges, where the snow is currently still high, spiked today and yesterday. From an average of low teens a few days ago to single digits last week. Today and yesterday the temperature has risen above 15 degrees C. The temperature has stayed above 15 degrees for over 5 hours in the Skeena Mountains north of Kispiox at times getting well above 16 degrees.
In the Tsai snowpack which empties primarily into the Copper River the temperature hasn't reached quite that high or that sustained though it has hit 15 degrees and maintained that temperature for two hours yesterday.
The graphs attached below show the three measuring stations on the Skeena River with measurements taken at 3 pm, June 1. The top graph shows the Skeena measured at Usk. It shows an up and down trend directly correlating to the bottom graph, which is the monitoring station on the Skeena above the Babine River confluence. As the flow increases from the days melt it takes a few hours for the flow to reach Usk (approx. 12hrs). Currently Usk shows a downward trend and the Babine station shows an upward trend. The middle graph is at the Glen Vowell station, a mid point between the two. It reflects the same trends.
With the warm weather the snow pack is melting. The current weather forecast is continuing heat, 21 to 22 degrees Thursday and Friday with a 70% chance of showers for Saturday.
Keep your eyes on the Terrace Daily. This is a terrible forecast for bringing down the snow pack all at once. Only time will tell. The river has dropped below 10 metres, lets hope it stays this way.
Graph retrieved from Environment Canada at 6 pm June 1, showing a decrease in the height at the monitoring station north of Babine on the Skeena River. This indicates the Skeena may continue to drop.
