State Farm is raising homeowners insurance rates in Illinois by a whopping 27.2% beginning Aug. 15, according to a filing with the state last month. The rate hike, one of the largest in the state’s history, will affect nearly 1.5 million policyholders. New policyholders will pay the higher rates as of Tuesday.

Many Illinois homeowners will soon see their home insurance rates skyrocket due to the increase in extreme weather events.

State Farm says in 13 of the last 15 years, it paid out more than budgeted to cover damage from severe weather events in Illinois.
