Weather observers reported over 2 inches of rain in southern Wake County on Monday morning, causing some road flooding, but freezing rain that may come to the region Tuesday night and Wednesday morning would be much more worrisome.
The rain total at Raleigh-Durham International Airport was 1.08 inches over the nine hours before 10 a.m. Monday, but observers who are part of a volunteer network that feeds data to the National Weather Service showed 24-hour rain totals of 2.65 inches in Garner at 8 a.m., 2.19 inches in Garner and 1.88 inches in Apex an hour earlier.
The rain proved to be more than some drainage systems could handle, with Raleigh police closing Durham Drive at Tryon Road and state troopers reporting a ramp from N.C. 97 to U.S. 264 was flooded.
Water on Durham Drive backed up several feet deep during heavy rains that did not slacken until after 8 a.m.
Never miss a local story.
Relatively warm air kept drivers from having to worry about ice Monday, and it is unlikely Tuesday morning.
Wednesday could be risky, however.
The weather service issued a Winter Storm Watch for Tuesday night into Wednesday morning with possible significant icing throughout the Triangle. Forecasters were watching computer models of weather systems, but they said that freezing rain or drizzle could start late Tuesday and persist into the morning.
