(8:15PM - 10/26/19) The combination of Tropical Storm Olga and a storm system merging across the region continues to bring heavy rain, flooding and windy conditions to portions of the state this weekend.
A large swath of heavy rain has been moving across the state through the day today. This rain will continue into tonight, slowly ending from southwest to northeast across the state as the night goes on. Widespread rainfall totals of 1-3” have occurred across much of the state, with final rainfall totals of 1-4” expected across the state, with isolated higher totals possible. The widespread and heavier nature of the rain, combined with leaf drop clogging drains, has enhanced the flood potential a bit. Widespread reports of minor to moderate type flooding has been reported across many areas, including areal and street flooding.
Additionally, winds will be a concern as well. There was a period of higher winds across Southeast Illinois a few hours ago. Outside of this, winds have been on the lighter side thus far for most areas. Winds are not increasing a bit as the storm system organizes, and gusts of 20-45MPH possible across a good portion of the state tonight, with isolated gusts in excess of 45MPH likely across Eastern Illinois.
