Overview

Thunderstorms developed as a low pressure system moved across central Indiana. The storms produced a tornado along with some large hail.

EF-Scale

The Enhanced Fujita (EF) Scale classifies tornadoes into the following categories:

EF0
Weak

65-85 mph
EF1
Moderate
86-110 mph
EF2
Significant
111-135 mph
EF3
Severe
136-165 mph
EF4
Extreme
166-200 mph
EF5
Catastrophic
200+ mph
ef-scale
Tornadoes that fail to impact any ratable damage indicators on the EF-Scale are rated EF-Unknown (EF-U)
