Dry October for Castlegar

Wondering where all the precipitation was in October? Apparently, it was just waiting for November.

This past October was the fourth driest on record, as an upper ridge of high pressure dominated the weather pattern, according to Ron Lakeman, weather forecaster for the Southeast Fire Centre.

The monthly total amount of precipitation, just 7.4 millimetres, was all rain, he said.

“The only disturbances to produce rainfall in excess of 1 mm were a weak Pacific disturbance which provided a brief band of thundershowers during the afternoon of the 7th,” said Lakeman in a release. “An equally moisture starved disturbance provided 2.6 millimetres during the night of the 26th.”

The mean monthly temperature was close to normal, 0.4 of a degree cooler than the normal average during October.

High pressure and the resulting sunshine allowed for the warmest temperature of the month, 20.7 degrees, during the afternoon of 6th.

The coolest temperature was -4.6 degrees during the morning of the 30th.

Despite the lack of precipitation, no records were broken. Other notably dry Octobers were in 2002, 1987 and 1974 with 2.2, 5.0 and 3.8 mm of precipitation respectively.
