More rain expected in Prince George

Hey, guess what … it’s not over. More rain is expected today, enough to prompt Environment Canada to extend its special weather statement for Prince George.

Moist easterly flow associated with a deep Alberta low will continue to stream moisture across the Rocky Mountains and into B.C. today.

Most of these regions have already received significant amounts of rain over the past 24 hours, ranging from 15 to 30 mm, with higher amounts over the mountains, locally up to 30-50 mm.

On Canada Day in Prince George, 13.5mm of rain fell. It was a lot, but well short of the record 21.4mm of rain that fell on Canada Day in 1999. It will be even tougher to break the record today (not that we want to) as the wettest July 2 on record was in 2000 when 33.8mm of rain fell.

As the main band of organized rainfall slides further north today, rain will end rapidly this morning across the Cariboo but persist along an axis extending from Williston to Prince George to Blue River. However, the unstable airmass over regions to the south will favour the development of showers and thunderstorms later in the day. Some heavier showers and thunderstorms will have the potential of adding 10-15mm locally over short periods well into this evening.

Higher rainfall amounts are expected over the mountains, especially over the Williston, McGregor, and Cariboo regions where storm totals will reach 40 to 60mm.

Although the rainfall amounts may not be exceptionally heavy, the significance of this event is due to the potential for rising rivers levels. There is significant concern for high flows in the Quesnel River (Cariboo Mountains), the North Thompson (Blue River/Clearwater region), and South Thompson (Shuswap).
