Severe Thunderstorm Warning for Madison County, Montana: 60 MPH Winds and Small Hail Expected
A Severe Thunderstorm Warning has been issued for Madison County, Montana, as a strong thunderstorm moves through the area capable of producing wind gusts up to 60 mph and hail smaller than 0.75 inches in diameter. Residents should take immediate precautions as damaging winds can down trees, damage roofs, and create hazardous travel conditions.
Storm Hazards
The National Weather Service indicates the storm is capable of producing:
- Wind gusts up to 60 mph
- Hail smaller than 0.75 inches
- Frequent cloud-to-ground lightning
- Heavy rainfall that may reduce visibility and cause localized ponding on roads
While the hail is expected to remain below three-quarters of an inch, the strongest threat comes from the damaging straight-line winds, which can break tree limbs, damage power lines, and create dangerous conditions for anyone outdoors.
What This Means for Madison County
Communities across Madison County should prepare for rapidly changing weather conditions. Outdoor activities should be postponed until the storm has passed. Secure loose outdoor furniture, tents, and lightweight equipment that could become airborne in strong wind gusts.
Drivers should be prepared for sudden reductions in visibility from heavy rain and blowing debris. If you encounter downed power lines, stay away and report them to local authorities.
Safety Tips During the Warning
The safest place during a severe thunderstorm is inside a sturdy building.
Remain indoors and stay away from windows until the warning expires. If you are outside when the storm approaches, seek shelter immediately. Avoid open fields, hilltops, and isolated trees due to the threat of lightning. Never drive through flooded roadways if heavy rain develops.
Stay Weather Aware
Thunderstorms across southwest Montana can strengthen quickly, especially during the summer months. Continue monitoring forecasts, NOAA Weather Radio, or trusted local weather sources for updates as this storm moves through Madison County. Additional warnings could be issued if the storm intensifies or new severe thunderstorms develop.
