Brief Tornado in Linn County Sunday

August 28, 2016

Just after 4:30 PM Sunday afternoon, there was a storm spotter report of a tornado touch down near Troy Mills in northern Linn County.  No damage was reported.  The environment was not favorable for severe weather, so the tornado did not last long, nor did it cause damage.  It developed quickly, as an isolated shower with heavy rain developed just minutes before the tornado was reported.

The Storm Track 7 Forecast called for isolated storms to pop-up in the afternoon.  These showers and storms were what we call “pulse” showers and storms, where they build themselves up and drop heavy rain, then dissipate, then pop-up again.

Several viewers caught photos of the funnel cloud associated with this tornado.

River Flooding Update

August 27, 2016

The good news is, all of the rivers experiencing flooding in northeast Iowa have reached, or are reaching their highest point as of Saturday afternoon, and will be falling below flood stage as we head into the end of the weekend and early next week.  Still, parts of the Cedar River, and Wapsipinicon River have flood warnings.

Flood Warning

If you live near the Wapsipinicon River in Bremer County, you’ve likely noticed a rise in the river to right around Flood Stage.  The river will be falling the rest of the weekend.

A Flood Warning continues for the Cedar River at Cedar Falls, until early Monday morning.  Saturday afternoon, the river was cresting at around 91.31 feet, and will gradually fall to Flood Stage by Monday morning.  At 91.2 feet, flooding begins to cover portions of Lake Street.  Downstream in Waterloo, you may notice a rise in the river, but flooding is not forecast.

CF

River levels along the Turkey River are beginning to fall significantly.  The Turkey River at Eldorado is now below Flood Stage.  Minor flooding is still occurring along the Turkey River at Clermont, and continues to fall.

Major flooding is still occurring near Elgin, but is gradually falling.
