Gusty winds may also develop, but should stay below severe levels.
The overall threat of severe storms remains low at this time, but the greatest threat of severe weather will be after sunset, particularly between 10 p.m. and 1:30 a.m. Torrential rain causing flash flooding and damaging winds are the main hazards.

Futurecast timeline Friday, March 24
As of 12:30 p.m. today, parts of southern Indiana have already seen over 2" of rain with metro Louisville sitting a little under 1.5". Once all rain finishes late tonight, widespread totals of 2-4" will be possible with localized higher
All the heavy rain still to come may send area rivers and streams over their banks. Thankfully, no river is expected to experience major flooding, and the high waters should only be temporary.
The Ohio River is forecast to come close to flood stage late Saturday, but should stay within its banks. It'll be noticeably higher, though, into early next week. The Salt River will also be higher, but should stay within its banks.
Forecast river levels into early next week
Other rivers such as the East Fork of the White River near Seymour and the Muscatatuck River are already experiencing minor flooding. Muscatatuck is expected crest this weekend, but the East Fork may run high into early next week
The Blue River in Indiana near Fredericksburg will also experience minor flooding Saturday but quickly recede into Sunday.
Tips to help keep you and your family safe if flash flooding occurs:
- Avoid flooded areas altogether if the water depth is unknown
- Turn around, don't drown! 1-2 ft. of flowing water washes away vehicles
- 6 inches of flowing water will knock you off your feet
- Don't go into flooded basements before ensuring your electricity is off
Wind speeds pick up tonight and, much like our windstorm a few weeks ago, will be strong after rain ends. Expect sustained west-southwesterly winds tomorrow 20-30 mph with gusts between 45-50 mph.
