English to Spanish Art/Literary Journalism Natural disasters and "Biblical" style

Sentence where it appears:

Hungary: The Danube goes Biblical rising 24 feet in 12 hours and engulfs entire cities.

One try,

Hungría: el Danubio adquiere proporciones bíblicas, con una crecida de más de 7 metros [de altura] en 12 horas que inunda [anega/devora] ciudades enteras.

(Beside the "alternate wordings" it seems too long...)

Random House Websters:
Biblical 3. evocative of or suggesting the Bible or Biblical times, esp. in size or extent: disaster on a Biblical scale; a Biblical landscape.

Besides the "inordinate" length my concern is that Spanish dictionary at hand, “bíblico” just means “perteneciente o relativo a la Biblia”... and not sure if the "full meaning" comes across...

Other than that, any suggestion to improve the translation and/or correct it making it less “farragosa”... I mean, “less cumbersome” and more “terse”... will be greatly appreciated...

At least, at the time of my night (when I first wrote this question), it looked a bit overwhelming... then again, when I look at it this morning... looks like the waters settled down and returned to normal...

Hungría: el Danubio se sale de madre, ascendiendo más de 7 metros en 12 horas y anega ciudades enteras.

This 2nd try would be a shorter version, but somehow I’d like to have the Bible theme there, intertwining with some of the Flood, the Noah Ark and that type of imagery...

I take you get the idea.

I’d appreciate yours!

TIA!
