The primary risks include damaging winds, heavy rainfall, and localized flooding. An isolated tornado cannot be ruled out. Counties under the Severe Thunderstorm Watch include LaPorte, Starke, St. Joseph, Marshall, Porter, and Lake in Indiana, as well as Berrien and Cass in Michigan. Residents in these areas should remain vigilant, especially during the late afternoon and evening hours when storm activity is expected to peak. Flood-prone areas are particularly at risk due to the potential for heavy downpours.
