I learned this the hard way when engineering microwave links to withstand rain rates based on historical data.
Many of my links that the calculators said would have >99.999% availability saw a cumulative downtime in 2020 over 1hr due to much higher peak rain rates than historically measured.
I now engineer the links to handle double the historically measured rain rates.
