Montgomery County Emergency Management Coordinator Brian Hamman said today his office received some calls this (Thursday) morning with regard to an Outdoor Warning Siren that was activated last night during the Severe Thunderstorm Warning in Red Oak. Hamman says the siren was not activated by the Communications Center and was potentially struck by lightning or received an electrical surge at the pole.
Hamman says the City of Red Oak has contacted the sales rep for the siren and they will be investigating the cause of the activation. The sirens can be activated during Severe Weather if there is an immediate threat to property and life due to strong winds or extremely large hail.
Shelby County Emergency Management Coordinator Bob Seivert said today (Thursday), that despite the fact some spotty rain had fallen throughout the County, and while every bit helps, the County will remain in the HIGH Fire Danger category until at least Monday, when the next update will be provided on conditions in the County.
Seivert says on Wednesday, National Weather service forecasters were very close to declaring a Red Flag condition for northeastern Nebraska. Wind and very low relative humidity are two of the several parameters used in determining that classification. Red Flag conditions are the most severe for the spread of fire in any given area. The rarity of these designations, underline how significant they are, when issued, according to Seivert, who says also that the forecast is not encouraging for any sustained rainfall over the next week.
Storms that formed in Nebraska late Wednesday night, moved into parts of western and southwest Iowa early this (Thursday) morning. The first warnings for our listening area were broadcast at around 11:40-p.m., and affected eastern Douglas County in Nebraska, and Western Pottawattamie County in Iowa. About 20-minutes later, additional warnings were issued for northwestern Mills and southwestern Pott. Counties. According to the National Weather Service, half dollar-sized hail fell near Lake Manawa, shortly after midnight.
About 45-minutes later, severe thunderstorm warnings were issued for eastern Mills, southwestern Montgomery, and extreme northwestern Page County. Penny-sized hail was reported to have fallen three-miles west of Pacific Junction at around 12:25-a.m., according to the Weather Service. As the storms in southwest Iowa moved out to the southeast, other storms moved into western and northwest Iowa and tracked east.
Thunderstorm warnings went out for Crawford and Sac Counties at around 1:45-a.m. It wasn’t long afterward that penny-to-quarter sized hail began to fall in Mapleton, which is in Monona County. Less than an hour after the warnings were issued for Crawford and Sac Counties, the Weather Service in Des Moines issued warnings for northeastern Audubon and northern Guthrie Counties. Those same storms moved into Dallas County and points east, bringing half-dollar sized hail to Adel, along with winds of up to 50-miles per hour, at around 3:30-a.m.
There were no immediate reports of damage early this morning.
