The heavy rainfall poses a significant risk of flash and river flooding, particularly in northeast Kansas and northwest Missouri, where the ground is already saturated. Urban areas and locations with poor drainage are especially vulnerable. Runoff from the rain is expected to raise river levels and increase current speeds, potentially impacting transportation and property. Additionally, there is a marginal risk (Level 1 of 5) for strong to severe thunderstorms, with damaging winds being the primary hazard.
