Water turning into the blood doesn't have to mean the water LITERALLY turns to blood, but this can be explained by just so many dead people on the waters that they become bloody, and giant hailstones don't NEED to mean LITERAL GIANT hailstones from a big thunderstorm, but rather giant catapult stones from Roman catapults.
