• Rain threatens the Midwest
  • Up to 5 inches expected
  • Chicago and Omaha at risk

The Midwest is facing another week of hazardous weather, with new rounds of intense rainfall capable of worsening conditions in already saturated areas.

September started exceptionally rainy in some areas and, in certain places, it’s already the wettest start to the month on record.

The situation could become more complicated between Sunday and Thursday, when several storms repeatedly hit the same corridors and increase the likelihood of sudden flooding.

Large metropolitan areas like Chicago, Milwaukee, Des Moines, and Omaha are included in a level 2 out of 4 flash flood threat until Wednesday.

Floods Threaten the Midwest

A system coming from the northwest Pacific will arrive in the Midwest between Sunday and Monday, picking up moisture as it moves into the region.

Although the low pressure will strengthen mainly over Canada, the associated cold front will favor conditions for potentially severe storms on Monday.

The severe risk level 1 out of 5 extends from Wisconsin to Nebraska, with damaging wind gusts being one of the main threats.

Around Omaha, the danger increases to level 2 out of 5 due to the possibility of a more concentrated area of strong storms forming.

“At this time, if the morning storms move away, there will be a possibility of severe weather phenomena,” said the FOX Forecast Center.

The situation could become more delicate as the cold front advances and becomes nearly stationary, allowing new storms to repeatedly cross similar areas.

Mozambique Channel moisture will fuel these storms and could generate rainfall with intensities of 1 to 2 inches per hour.

Iowa and southern Minnesota could accumulate 3 to 5 inches, while the corridor between Chicago and Omaha could receive 2 to 3 inches.

Saturated Soils Increase Flood Risk

The problem is that Iowa, Minnesota, and other parts of the Midwest already have saturated soils, so smaller amounts of rain could trigger flooding quickly.

Successive storms can accelerate runoff and cause dangerous water accumulations in streets, low-lying areas, and sectors near small streams.

The flash flood risk remains at level 2 out of 4 daily until Wednesday, while the rain could continue at least until Thursday morning.

This keeps millions of Midwest residents under surveillance during a week when each new storm could worsen the problems left by the previous ones.

What Can You Do About Flash Flooding?

Flash flooding can develop rapidly when intense rainfall hits saturated ground, especially in urban streets and low-lying areas.

Drivers should pay special attention to flooded roads, where the depth of the water can be difficult to calculate during a storm.

Those living near small streams or flood-prone areas should follow local alerts as successive rounds of rain continue.

The threat could persist for much of the week, especially if storms concentrate again over areas that have already received heavy precipitation.
