The scale of dBZ values can be seen along the bottom of the image. dBZ is a logarithmic dimensionless technical unit used in radar.It is mostly used in weather radar, to compare the equivalent reflectivity factor (Z) of a remote object (in mm 6 per m 3) to the return of a droplet of rain with a diameter of 1 mm (1 mm 6 per m 3).

An intensity-duration-frequency curve (IDF curve) is a mathematical function that relates the intensity of an event (e.g. rainfall) with its duration and frequency of occurrence. [1] Frequency is the inverse of the probability of occurrence.
This is the first time reflective passenger plates had been issued since 1993. The changes also occurred to trailer plates at 6JP0-00, Class 2 commercial plates at 44-P000, and Class 1 commercial plates at the beginning of a new format, 0-AA000; this format would take effect after the exhaustion of the A-00000 to A-99999 series.

Heavy rain (Alberta to Southern Quebec: 50 mm (2.0 in) or more per hour. Pacific, Northern and Maritime provinces: 25 mm (0.98 in) per hour) Public bulletins will often mention the possibility of tornadoes; if a tornado is spotted or conditions are favourable enough for tornado development, the warning will be upgraded accordingly.

A massive cluster of thunderstorms occurred on July 11, 2004, with large hail and over 100 mm (4 in) of rain reported within the space of an hour in many places. [26] This "1-in-200 year event" flooded major intersections and underpasses and damaged both residential and commercial properties.
