Rainfall warning issued for:
   Fort Nelson, B.C. (088100)

Current details: 
Rain, at times heavy, is expected.

A low pressure system moving northwards across Alberta will spread rain to the Fort Nelson and Muncho Lake regions Sunday through Monday. Rain will begin Sunday morning, then become heavy at times Sunday night through Monday morning, and taper to showers by midday Monday. Total rainfall amounts near 70 mm can be expected by Monday afternoon. 

Given the wet antecedent conditions in the region this past month (including a similar weather system last weekend), the ground is already saturated in many areas. The prolonged moderate to heavy rainfall may result in higher overland runoff.
