Temps in the 40s on Tuesday and Wednesday caused quick snow melt, resulting in drippy gutters, soupy lawns and water-puddled streets.
But bigger issues could be ahead if the area receives significant rainfall.
According to a hazardous weather outlook issued Wednesday by the National Weather Service Quad Cities, an intensifying and very strong storm system is expected tonight and continue into Thursday, bringing thunder, dense fog and a half inch to 1.5 inches of rain.
"At this time of year, on frozen ground, (the rain) may result in some ponding issues and urban and small stream flooding," the NWS said. "There may be a lower risk of flooding due to generally low river levels, but smaller iced-up creeks may still come out of their banks in some locations.
"The threat of ice jamming will also be on the increase along some area rivers and streams late (Wednesday) and especially on Thursday," the outlook stated.
The NWS said melting snow Tuesday released a quarter inch to an inch of water into streams and drainage ditches. "The snow pack that still exists in eastern Iowa and northwestern and west central Illinois still contains anywhere from one to three inches of water," which will continue to become run-off.
Moline public works employees were taking proactive measures Wednesday, ensuring inlet and catch basins were clear of debris and packed snow so the melting snow and rain can get to the storm sewer system, according to public works director Mike Waldron.
Otherwise, it could cause large puddles and flooded streets, he said.
Municipal services general manager Doug House said workers were focusing on critical areas, below the hills in south and north Moline, to ensure rain and run-off will get away quickly.
Today is Wednesday, April 23, the 113th day of 2014. There are 252 days left in the year.
