LOOGOOTEE, Ind. — Local emergency officials and meteorologists are urging residents across Martin County to prepare for a significant outbreak of severe weather as a massive storm system moves from Illinois into Indiana on Wednesday, June 17, 2026.

The National Weather Service has placed a large portion of northern and northwest Indiana under a moderate risk for severe weather, which is a level four out of five on the severity scale. Central Indiana is currently categorized under an enhanced risk. Forecasters note that the system carries a volatile environment capable of producing long-lived, widespread, and potentially dangerous hazards. While the absolute highest risks are situated in the central and northern tiers of the state, southern Indiana remains highly vulnerable to the expanding storm complex.

Meteorologists indicate that all severe weather hazards are on the table for Wednesday, including intense tornadoes, very large hail up to two and a half inches in diameter, and destructive straight-line wind gusts reaching up to 80 mph. According to the Storm Prediction Center, the system is fueled by an unusually strong mid-level jet stream and deep atmospheric moisture, which will create a highly unstable environment as a warm front lifts across the region.

Timing is a critical component of this severe weather threat, with the most intense storms projected to impact Indiana during the evening and overnight hours. Forecasters expect initial storm development to begin by late afternoon, transitioning into a fast-moving line of thunderstorms that will sweep east and southeast across the state between 7 p.m. Wednesday and 2 a.m. Thursday. Because the highest severe risk coincides with nighttime hours, weather experts emphasize the importance of having multiple ways to receive warnings that can wake individuals up during sleep hours creating nocturnal storms.

For southern Indiana, including the Loogootee area, the primary threat is currently projected to manifest as a significant straight-line wind event as the storms organize into a linear complex. However, because low-level wind shear will remain highly favorable for rotation, embedded supercell structures and localized tornadoes cannot be ruled out even within the main line of storms. Emergency management personnel remind residents that straight-line winds can cause damage just as severe as a tornado and often impact a much wider geographic footprint.

Public safety officials including at the Daviess County Emergency Management Center advise residents to finalize their severe weather safety plans ahead of the storm’s arrival. Awareness and proactive preparation are vital. Families should identify their designated safe place, such as a basement or an interior, windowless room on the lowest floor of their home. Charging mobile devices, keeping flashlights nearby, and programming weather radios are recommended steps to maintain situational awareness throughout Wednesday night as this dangerous system tracks through the region.
