This blog post explains the approaching heavy-rain event expected to impact parts of Arkansas, Missouri, and Kentucky this week. It outlines the primary hazards — especially flash flooding — and provides practical guidance for residents and local responders.
Drawing on recent forecast guidance and three decades of meteorological experience, I summarize where the greatest risks lie and expected rainfall amounts. I also describe steps you should take now to stay safe.
Storm overview and primary hazards
A slow-moving storm system is forecast to stall across the central and lower Mississippi Valley. This will produce prolonged and heavy rainfall over already saturated soils.
When a storm moves slowly, the same area can receive repeated rounds of rain. This dramatically increases the risk of flash flooding and river rises.
Flash flood watches have been issued for multiple counties in Arkansas, Missouri, and Kentucky. Local emergency managers are warning that some locations could see several inches of rain in a short period.
Given recent wet spells, many streams and rivers are running high. Even moderate additional rain can cause rapid, dangerous rises in water levels.
Where the heaviest rain will fall
The greatest threat area is focused over the Ozarks and the lower Mississippi Valley. Here, topography and existing river systems enhance flooding potential.
Forecast models indicate some pockets could receive totals exceeding 6 inches of rain within just a few days. The most intense accumulations are expected in narrow bands of heavier convection.
Why saturated soils and terrain matter
When soils are saturated, they can no longer absorb additional rainfall. Much of the incoming precipitation becomes overland flow.
This accelerates runoff into streams and rivers. Both the speed and volume of floodwaters increase.
Hilly and forested areas in the Ozarks can experience particularly fast runoff into narrow valleys. This can lead to localized flash flooding that develops with little warning.
Likely impacts on communities and infrastructure
Officials warn of the potential for power outages, travel disruptions, and damage to low-lying homes and infrastructure. Roads that normally drain quickly can become submerged.
Driving through moving water is a leading cause of fatalities during floods. Local emergency management agencies are preparing shelters and sandbag stations to support residents who may need to evacuate or protect property.
Monitor local guidance and be prepared to move to higher ground if advised.
Practical safety steps to take now
Below are immediate actions I recommend for people in the threatened areas — all rooted in best practices developed over decades of flood responses.
What to expect as the storm evolves
Forecast guidance shows the system shifting eastward by the weekend. Flood hazards can linger after rainfall ends — rivers may continue to rise for days.
Stay alert into next week, especially if you live near major streams or levees.
