![]() As such, raw weather radar data is characteristically noisy given how common these types of interference are. Among others, the radar can also see returns from non-meteorological objects such as birds, bugs, dust, terrain, buildings, and other sources of radio waves at similar frequencies. However these are not the only objects that will reflect the radar signal. Meteorological targets would include objects like rain, snow, and hail. Reflectivity, put simply is the amount of return that the radar sees at a given azimuth and range. Radar operates by sending out a radio wave pulse that will interact with objects and 'reflect' some portion of that signal back to the radar reciever. While it may present a temporary inconvenience, it is better for water to pool on the street than in residents' basements," the statement said, in part.Base reflectivity is the most basic of all NEXRAD products and can be used to illustrate some fundamental principles. As our climate changes and we see heavier rain events in compressed periods of time, it is difficult for our sewer system to move the water efficiently. "To assist with moving water into the wastewater system, please do not use extra water to shower, do laundry or dishes while experiencing storm conditions.

He said he's never seen so much rain come down. Tim Williams said his basement filled up with nearly three feet of water. The mayor is a resident of the city's Austin community. And again we have the full force of government on display today," Johnson said. ![]() ![]() ![]() "And we're not just showing up to say hi, we're showing us to hear and listen. The flooded Riverwalk had receded by Monday, and the city was cleaning up the leftover debris and muck. Sunday's flooding meant city officials had to reverse the flow of the river into Lake Michigan. Monday, a swim advisory was still in place at Foster Beach, Rainbow Beach and South Shore Beach, while the only remaining swim ban was at Marion Mahony Griffin Beach. The bans were initially put in place due to unsafe water quality from elevated levels of bacteria after the rain forced the city to reverse the flow of the Chicago River into Lake Michigan to prevent downtown flooding.Īs of 4 p.m. Swim bans have been lifted at almost all Chicago beaches as of 3 p.m. Some people are still cleaning up Monday after record Sunday rainfall shut down roads and the Riverwalk, stranded drivers and flooded basements.ĬHICAGO (WLS) - Chicago is cleaning up after torrential rain led to flooding problems Sunday. ![]()
