The storm could dump as much as 10 trillion gallons of rain on North Carolina alone, according to meteorologist Ryan Maue of weathermodels.com. That’s higher than the maximum capacity of Lake Mead, the reservoir that serves water to Arizona, California, and Nevada. (To visualize that, the lake is currently only filled to 38% of its capacity.)

Maue’s prediction is based off of the seven-day rainfall summary from the National Weather Service, factoring in the average and maximum rainfall estimates.

He further notes that the initial estimates from Harvey were much lower than the actual totals. (Harvey ultimately dropped 33 trillion gallons of rain on Southeast Texas and Louisiana.)

South Carolina and Virginia are not going to escape a deluge, either. The storm is expected to stall once it hits land, then slowly move through South Carolina and up into Virginia, losing windspeed, but still soaking the states. (Forecasters say parts of South Carolina could receive up to 20 inches of rain.)

Need to visualize 10 trillion gallons a little differently? That same amount of water could also:

• Fill 15 million Olympic-sized pools
