Warren County

Every recorded tornado

1. Injuries and deaths are for the tornado’s whole path, which may extend beyond the county. Deaths recorded within Warren County: 0.
2. Weak tornadoes were under-recorded before Doppler radar coverage became national in the early 1990s, so earlier decades read low. Ratings use the Fujita scale before February 2007 and the Enhanced Fujita scale after.

Smoke overhead

1. A smoke day is a date on which a smoke plume traced by NOAA Hazard Mapping System analysts from satellite imagery covered this place's point (the county's population centre or the city centre). Counts here are of medium or heavy smoke. Since 2018 analysts have often drawn light smoke as one area over most of the continent, so light-smoke counts are not comparable from year to year. The plumes show smoke anywhere in the air above, not air quality at the ground, and smoke hidden by cloud is missed.

River crests

River gauges

1. Crests are the highest and the recent crests the National Weather Service lists for each river gauge in the county that has a flood stage, not every flood. Flood categories use each gauge's current flood stages; crests from before levees, dams or channel changes may not be comparable. Crests measured on an old datum are left out of the rankings.

1. The Palmer Drought Severity Index is computed by NOAA each month from the county's average temperature and precipitation, relative to the county's own climate. Zero is normal; -3 or lower is severe drought and -4 or lower extreme drought. It describes the long-term balance of moisture, not water supply or crop losses.

Every earthquake of magnitude 4 or more within 50 miles

1. Earthquakes of magnitude 2.5 or more in the USGS Comprehensive Catalog since 1900. Within 50 miles means the epicentre lies within 50 miles of the county boundary (or inside the county).
2. Small earthquakes were under-recorded before the modern seismic networks of the 1970s and are still missed in remote areas, so early decades read low. Magnitudes are as the catalogue reports them and mix scales (moment, local and body-wave).

   National Weather Service narrative

   Numerous thunderstorm complexes marched across the northern half of the Indianapolis CWA starting on the evening of July 4th. The storms gradually started effecting southern areas of the CWA as well. The onlslaught of periodic heavy rain didn't end until the 11th. This caused major flooding major flooding all along the Wabash River. For the month of July, this type of flooding was likely unprecedented from Lafayette to Vincennes. For a more devasting flood later in the agricultural season, one must go back to August 1875.Location: FS in feet: Crest in feet: Date:Lafayette 11.0 25.05 7/10Covington 16.0 28.92 7/11Montezuma 14.0 30.35 7/12Clinton 18.0 29.50 7/13Terre Haute 14.0 25.09…

2. Jan 22, 1999Flood, Warren$1.0 million
   National Weather Service narrative

   Rapid snow melt and heavy rain on the 21st and 22nd from 2 to 5 inches caused widespread flooding all along the Wabash River from Lafayette to East Mount Carmel. Flooding was the highest since April 1994 as crests were generally around 10 feet above flood stage. As flooding was nearing an end, more rain on the 31st caused the flooding to continue into February. The following are crests for various locations along the Wabash: Lafayette - 21.83 feet (flood stage is 11 feet); Covington - 26.18 feet (flood stage is 16 feet); Montezuma - 26.30 feet (flood stage is 14 feet); Clinton - 25.75 feet (flood stage is 18 feet); Terre Haute - 22.42 feet (flood stage is 14 feet); Riverton -…

   National Weather Service narrative

   A man attempted to cross a bridge over the swollen Wabash River and was swept to his death. It was after dark, and water was over the road approaching the bridge. It is believed that the man crawled through the car window in an attempt to get to safety and was swept away by the strong current. The search was called off on 12 January to wait until the waters receded, due to the hazardous nature of the search.
