The National Weather Service has issued a flood watch for the South Bend area, with severe thunderstorms expected to develop in two waves overnight. Rainfall rates up to 1 inch per hour could quickly overwhelm low-lying areas, leading to flooded roads on major routes like I-69, I-80/90, and US-30. In addition to flooding, the storms may also produce damaging winds and isolated tornadoes, potentially causing power outages and downed trees.

Why it matters

Severe weather events like this can have significant impacts on transportation, infrastructure, and public safety in the South Bend region. Flooding poses risks to drivers, while high winds can lead to power disruptions and property damage. Preparing residents and coordinating emergency response is crucial to mitigating the effects of these storms.

The details

According to the National Weather Service, the first round of storms is expected between 5 p.m. and 8 p.m. in southern portions of the region, followed by a stronger round between 9 p.m. and 3 a.m. across northern counties. The repeated storms moving over the same areas could push rivers back into flood stage, with the potential for standing water to develop quickly on major roadways.

• The flood watch is in effect through Wednesday evening.
• The first round of storms is expected between 5 p.m. and 8 p.m.
• The second, stronger round of storms is expected between 9 p.m. and 3 a.m.

What’s next

Residents should avoid driving through flooded roadways, charge devices, and monitor alerts closely overnight. The flood threat may linger into Wednesday as rivers respond, and additional warnings are likely if rainfall intensifies.
