On occasion, the remnants of a hurricane or tropical storm will track across central or southeast Illinois. The image below, courtesy of NOAA's Office for Coastal Management hurricane mapping system, shows the observed tracks that have occurred within 125 miles of Decatur. (That search parameter was chosen to best incorporate our forecast area.) The colors of the lines represent the intensity of the storms, shown by the legend at lower right. (H1 through H5 represent category 1 through 5 hurricanes, TS indicates a tropical storm, TD is a tropical depression, and ET means the system is classified as "extratropical".) Information on the tracks comes from the archives of the National Hurricane Center, as well as the Hurricane Research Division of NOAA's Atlantic Oceanographic and Meteorological Laboratory. 

For the most part, such tropical systems make landfall in Texas, Louisiana, or Mississippi before moving up through central Illinois. These particular storms maintained an identifiable circulation along the entire track. There have been other systems that have lost the circulation, but the remaining moisture was absorbed by another system moving through the region.

The map below zooms in on Illinois. As one might expect, most systems have lost their tropical characteristics by the time they reach our area (indicated by the gray lines), since they have been long cut off from their fuel source over the Gulf of Mexico or Atlantic Ocean. However, there have been a few still considered to be a tropical depression in our area (blue lines), and one that made it all the way to south central Illinois as a tropical storm (green line).

It curved northeast in Arkansas and moved into southeast Illinois before degenerating into a remnant low northeast of Effingham. Rainfall of 1/2 to 1 inch occurred between I-55 and the Indiana border, which was welcome due to an ongoing drought.

Hurricane Gustav
Aug. 25-Sep. 5, 2008

It curved northeast and the extratropical remnants tracked just south of a St. Louis to Champaign line before ultimately dissipating over far southern Quebec. Wind gusts of 50-60 mph occurred over some areas south of I-70 on the 14th. The tropical moisture was absorbed into a frontal system, which produced 4-6 inches of rain from the 13-15th over most of the northwest 2/3 of Illinois, and resulted in flash flooding.
