“An upper low in Southern Alberta is spreading extensive moisture across Southern British Columbia. Rain has spread across the Southern Interior and into parts of the Central Interior. Rainfall amounts so far have been in the 20 to 40 mm range except over the southeast where rainfall amounts ranged from 40 to 80 mm,” read an Environment Canada bulletin dated 3:48 a.m. this morning.
“Additional rainfall amounts today will be in the 10 to 20 mm range but over the southeast amounts up to 30 mm are possible. Heavy rain will gradually ease over many areas later today as the low weakens. However rain will continue over the southeast where a further 10 to 20 mm is possible tonight,” the bulletin went on to say.
“A very moist area of low pressure is approaching southern British Columbia bringing widespread rain into the British Columbia Interior,” read an Environment Canada bulletin.
“With this ample supply of moisture and the slow moving nature of the low, heavy rainfalls are likely. Widespread rainfall totals of 40 to 60 mm is expected over a two day period with locally higher amounts possible especially where rain is enhanced by local terrain,” it went on to say.
Ten to 40 mm of rain is forecast specifically for Grand Forks today with 15 to 25 mm tonight – a high of 15 C and a low of 10 C is also forecast.
Five to 10 mm of rain is forecast for tomorrow with a high of 13 C and a low of 10 C.
