However, don't forget that this IS 2020 - the year of highly improbable events. Who would've guessed that two hurricanes would hit almost the same spot this year or that we'd have run out of names by now, or that (I'm from Boulder, Colorado so I have to throw this one out there) a wildfire would've burned through 100,000+ acres in a day, or that an amped-up cold virus would've shut down the country? This is the year of Murphy's Law and who knows how those levees were actually put together - not what was on the specs but what was actually done or what those levees are actually capable of holding back. Given this year though, if there's ANY possibility of them failing - they'll fail.
