"A thing can be 'unprecedented' only once. After that one time, the 'precedent' has been set. After that happens, a thing can become 'normalized'. Super-floods wiping out geographical areas including major cities - seen it before haven't you - no surprise then next time, and the time after that, and the time after that. Happens all the time - climate change you know ...the Zio-A21 would-be world-redesigners will say.
Dams, reservoirs, levees, dikes, etc - water-control systems - can be allowed to flow, be restricted, be diverted all sorts of different ways, all the way down any particular system. "River-engineering" it is called. Constructed so as to allow the directing of any desired amount of water wherever the 'river-engineers' want it, or need it, to go. Flood location 'X' on demand? Pull a few levers, push a few buttons - presto - how much water you want.
MSM does the rest. 50" (or more) rain? ...6pm news coming right up. "
The new precedent now is hurricanes that can do anything - stop, go, turn right, turn left, u-turn, intensify, weaken, speed up, slow-down, and then vanish. This was just demon-strated to the world. Be aware. Rev. 18:4
