Tropical cyclone (an organized area of low pressure that develops over tropical waters) remnants can move into central Indiana. The most common impact to central Indiana from these remnants is rainfall, sometimes heavy. However, they can bring damaging winds and help spawn tornadoes. The remnants of Hurricane Ike brought damaging winds to central Indiana in 2008.

A map of tropical system tracks from both the Pacific and the North Atlantic Basins shows central Indiana is near the northwest edge of the tracks.

The NOAA Office for Coastal Management has a searchable archive for tropical system tracks. For this search for systems near central Indiana, any system that originated in the North Atlantic Basin and moved within 100 nautical miles of Indianapolis was considered.

There were 19 systems whose remnant low pressure areas moved nearby  the area from 1866-2017. Figure 2 is map of the systems that did so.

Figure 3 is a zoomed in version of the track map. Most of the systems have their names plotted on the map, but due to space constraints a few are not.

The interactive map of this search is available at the NOAA Office for Coastal Management website. Current tropical systems are monitored by the National Hurricane Center.

See farther down the page for details about the systems impacting the area.

The multiple tropical remnants in 1979 caused significant flash flooding in parts of central Indiana. See this excerpt from the Storm Data publication for details.

Notes: Moisture from other tropical remnants may have impacted the area and are not listed here. Some notable remnants, such as Katrina (2005) fell just outside the 100 mile radius. Other parts of Indiana may have had much higher impacts than central Indiana for some remnants.
Additional information can be found by expanding the search parameters on the archive website and by looking through the Storm Data publication archives.
