Pike, Dubois Counties could see big rainfall from Isaac | Weather

Dubois and Pike Counties could see four to five inches of rain as the remnants of Hurricane Isaac blow through the Tri-State over the holiday weekend.

A new map from the National Weather Service has the area in a band that will bring steady, heavy rain between Friday and Sunday.

As rain and wind approach, the Indiana Department of Homeland Security (IDHS) is asking everyone to join emergency management officials in preparing for potential storms and localized flooding.

Central Indiana and areas south along the I-70 corridor, including Terre Haute, Indianapolis and Bloomington, are expected to receive the heaviest amounts of rainfall. 

Rain is expected to fall steadily from Saturday through Monday and cause only minor flooding in some low-lying and river bank areas. Locations that may be particularly prone to flooding include areas around the Wabash, Eel, and lower White rivers and the east fork of the White River around Jackson County.

A cold front from the north may also mix with warm air from Hurricane Isaac and create the potential for strong straight line winds and scattered tornadoes. Unlike typical Indiana springtime tornadoes, these may be shorter lived, but harder to spot because they may be masked in rain.

“While at this point we only anticipate receiving minor, localized flooding in portions of Indiana, IDHS and local officials are monitoring the situation and are prepared to respond to any weather related emergencies that may arise," said IDHS Executive Director Joe Wainscott. “We’re asking all Hoosiers to also be alert and prepared.”
