# What does a dot inside two parenthesis mean on a weather depiction chart?

Earlier today, a friend asked me what this symbol (referring to an airport in Canada) on a weather depiction chart represented. I didn't know. (Full chart available here)

From here, $(\cdot)$ means that there is precipitation within sight, reaching the ground, not at the station, but < 5 km from the station.
