WednesdayFeb21Winter
The rain across the area is expected to change to freezing rain and sleet later this evening. Ice accumulations up to a tenth of an inch are possible across the winter weather advisory area tonight, especially on elevated surfaces. This may result in difficult travel conditions during the early morning commute on Wednesday.
As we warned, the conditions exist for extreme flooding. The ground is still in a frozen state, most of the snow is now gone, but turned into water and moderate to heavy rains caused a pooling affect. This water will remain with us and some turn into ice patches in the roadways so please be cautious.
The poor soul below did not head our warnings in the early morning hours. Reports state that the person in question was evacuated from the vehicle by Porter County Emergency Services. The family transporter the person to the hospital for evaluation. Given an area like the one below near 550 South in Porter Township is hard to judge unless you have intimate familiarity with the road. So please do not take the chance. If you see a water covered road, turn around and seek another route. In this case the water was at least 28-30″ deep. At that point the car could have very likely been pushed into a deeper area where the person could have been trapped in waters 4′ deep.
Now that the temperatures are dropping and we are looking at a northern air pattern, the precipitation will turn into sleet. So both Flood Warning and Winter Advisory are now in effect. Surfaces will become slick and icy during your commute. Please take it slow and reserve extra time to get to your destination.  Many of the drainage ditches on the roadside in rural areas  are flooded, so additional water damage can and will occur if you slide off the road not to mention the risk of personal injury or drowning.
Ok cupcake, those are the warnings. As hard as we try, some of you just don’t listen. We will reserve the social commentary for another day. Too much information for some of you to take in. Be safe and drive carefully.
