60 Inches of rain in a wide spread area over 2 days. Seawalls would do nothing, upstream dikes would do nothing, prepare... Ok Canada.... Lets take Toronto, lets take 600 miles and drop 60 inches of rain over it. Now lets pretend that you can only clear the water from your streets twice a day because of tidal flows. There is nothing that could be done here. I live in Texas and this is a insensitive, needless blaming article.
