Flooding Likely Next Week

 

Hydrologic Outlook

RIVER FLOODING WILL BECOME INCREASINGLY LIKELY BY LATE WEEK...

Heavy rains on Thursday left us with very high moisture levels in the top six feet of our soil, especially across southern Indiana and north central Kentucky. While surface soils will benefit from dry weather today and Sunday, deeper soils will be slower to lose their moisture.

A slow-moving system will interact with a rich moisture supply Monday night into Tuesday, resulting in widespread rain and possibly heavy precipitation. Bands of moderate to heavy rainfall may result in areal flooding as soils recharge.

Additional waves of precipitation, though likely not as heavy as what we are expecting on Tuesday, will add to rainfall totals Wednesday night through Friday. These events following the Tuesday rain will encourage river flooding.

Although the heaviest rainfall amounts this week are expected to fall just south of where the heaviest rain fell this past Thursday, all river basins are under a threat of at least minor flooding by mid to late week.

Tuesday through Friday rainfall amounts of 2 to 5 inches are currently in the forecast, with amounts increasing from north to south. About half of that is expected to fall on Tuesday.

We still have a few days before these systems arrive, and changes in the forecast are certainly possible. Be sure to stay up-to- date over the holiday weekend as new outlooks are issued, especially if you have interests in flood plains or along streams, including the Ohio River.
