What to Expect in Terms of Weather Extremes
Although Louisville’s weather is generally moderate, the city is not immune to extreme weather events. The area is located in what is known as “Tornado Alley,” so severe thunderstorms and tornadoes are a possibility during the spring months, especially in March, April, and May. While tornadoes are rare, they do occasionally impact the area, so it is important to stay informed during storm season.
Another consideration is flooding, particularly in areas near the Ohio River. Heavy rainstorms, especially in the spring, can lead to localized flooding, though modern flood control systems have reduced the impact of such events.
