you will see a spike in coverage, generally towards North Northeast. The effective power in that direction is often reported 20-30 dB over the Maximum power.
For example, CHLF's max ERP is 10 KW, but the effective power to the NorthEast is over 2 MW.

Found a another plot with a northward overpower anamoly: CIHF-DT channel 8 in Halifax, NS. Max ERP: 1.000 kW, Eff Power: 6.564 kW
