The National Weather Service expects that significant flooding will develop along the Muscatatuck, White and East Fork White rivers in southern Indiana by the weekend.

The National Weather Service says Indianapolis received more than 4 inches of rain Tuesday, breaking a 100-year-old record. Heavy rains also fell in eastern Indiana, prompting flash flood warnings.

An average of 9 inches, more than twice the normal level of 4.2 inches, was measured last month at 200 recording stations across the state. As much as 18 inches of rain fell in parts of northern Indiana.
