Sarnia weather radar

Thank you for reporting this station.

The colors are the different echo intensities reflectivity measured in dBZ decibels of Z during each elevation scan. Reflectivity designated by the letter Z covers a wide range of signals from very weak to very strong. So, a more convenient number for calculations and comparison, a decibel or logarithmic scale dBZ , is used. The dBZ values increase as the strength of the signal returned to the radar increases. Each reflectivity image you see includes one of two color scales. The other scale near left represents dBZ values when the radar is in precipitation mode dBZ values from 5 to

Sarnia's sewer system was overwhelmed by the amount of rain that fell during Thursday's thunderstorms. Environment Canada said a total of 45 millimetres of rain fell in Sarnia Thursday, of which 44 millimetres was recorded during the night-time storms.
