Millions of people will remain at risk for strong to severe thunderstorms Tuesday night from the Midwest through the Ohio Valley.
A few of the major cities that could experience a round of damaging winds and flooding downpours include Wichita, Kan., Peoria, Ill., Omaha, Neb., Kansas City, Mo., Columbus, Ohio, Cincinnati, Ohio, Indianapolis, Ind., and Pittsburgh, Pa.
While one complex of thunderstorms continues to track through the Upper Ohio Valley, additional complexes of thunderstorms may form later Tuesday night.
Powerful wind gusts are a concern with any complex of thunderstorms that form. Winds to 60-70 mph can lead to downed trees.
Neighborhoods may lose power during these storms as strong winds and falling trees could knock down power lines. Additionally, falling trees may lead to damages to homes, vehicles and other property.
Flash flooding will also be a large concern with these storms. Heavy downpours can quickly drop more than an inch of rain in less than an hour.
There have already been numerous reports of flash flooding throughout central and eastern Ohio with an initial complex of thunderstorms.
With this much rain falling in such a short period of time, small creeks can quickly turn into vicious flowing bodies of water. If driving during a flash flood, try to avoid driving on roadways that have water flowing across them.
Just a few inches of flowing water is enough to move your car. Water over roads may be deeper than you know. If you try to drive through flowing water, it can be life threatening.
Be mindful of flood watches or flood warnings in effect for your area. A flood watch means that a flood may occur, while a flood warning means that a flood is occurring or is imminent.
