Carmel

Every recorded tornado

1. Injuries and deaths are for the tornado’s whole path, which may extend beyond this area.
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 in Hamilton County, the county that contains Carmel.

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.

The drought index is for Hamilton County, the county that contains Carmel.

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.

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 city centre.
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 central Indiana from the evening of the 4th and not ending until the 11th. This caused near major flooding along the White River in Hamilton and northern Marion counties. The White River at Noblesville reached its highest level since March 1913. However, measured peak flow at Noblesville was about 30% less than the April 1964 flood. Major agricultural damage resulted along the entire length of the White River.

   National Weather Service narrative

   A series of supercell storms dumped hail from golfball to softball size across a large portion of the northern half of the IND CWA. The storms moved across a warm front that stretched across central Indiana. Numerous cars, car lots and homes had extensive damage estimated around 75 million dollars. Frankfort, Anderson and Muncie were hardest hit. In addition, three homes in New Whiteland were burned to the ground by a lightning strike. Later in the evening, a squall line moved across the same area producing only isolated hail reports.

3. Sep 1, 2003Flash Flood$5.0 million
   National Weather Service narrative

   Record rainfall event occurred across central Indiana starting in the evening of August 31 and continuing through the morning of September 2. The heaviest rain occurred along an axis from Vigo to Clay to Putnam to Hendricks to Marion to Hamilton to Madison, Delaware and Randolph counties. Many spots near the axis received 8 to 10 inches over the 30 hour period. This resulted in widespread flash flooding and flooding along small creeks. There were numerous evacuations from homes and rescues from vehicles. Many schools were closed. Many neighborhoods that never saw flooding before were flooded. There were also hundreds of flooded basements. The National Guard was activated to help…

4. Jun 22, 2010Lightning$3.5 million
   National Weather Service narrative

   Newspaper and broadcast media reported a lightning strike was the suspected cause of a fire of a shopping strip in western Carmel, Indiana. Firefighters think lightning struck the El Rodeo restaurant, located in the 12-unit Weston Shoppes, and quickly spread across the shopping center. The strip mall owner said continuing lightning strikes prevented firefighters from hosing the flames from their ladder trucks, hampering their efforts to save the building. Damage estimates, not including each store's inventory, could be between 3 and 4 million dollars. Firefighters were still on the scene 8 1/2 hours later.

5. Sep 1, 2003Flood, Hamilton$3.0 million
   National Weather Service narrative

   8 to 10 inches of rain fell across central Indiana during the Labor Day weekend causing major flooding along parts of the White River. In fact, Indianapolis received the most rain ever for a calendar day (7.2 inches) breaking the old record set in 1895 (6.8 inches). According to a local newspaper account, nearly 3,000 residents across central Indiana applied for flood assistance and flood damage was estimated in excess of 20 million dollars. SEMA reports indicated more than 300 homes and nearly 60 businesses were flooded. Nearly 200 people were forced to evacuate their residences. The cities of Muncie and Anderson had near major flooding as the river crested at its highest level…

6. Jan 22, 1999Flood, Hamilton$1.7 million
   National Weather Service narrative

   Heavy rain of up to 5 inches on the 21st and 22nd combined with rapid snow melt upstream causing widespread flooding along the White River from Muncie to East Mount Carmel. Crests ranged from around a foot above flood stage along extreme eastern sections of the White to around 10 feet above flood stage across extreme western sections. Flooding along the river in Hamilton and northern Marion counties were the highest seen since December 1990 and January 1991. Many homes and streets were flooded, and a few rescues took place. The following are various crests along the river: Muncie - 9.62 feet (flood stage is 9 feet); Anderson - 12.8 feet (flood stage is 10 feet); Noblesville -…
