Here’s how much rain Raleigh, Durham and Chapel Hill got from Debby. Latest counts

Five-day rainfall totals after Debby — which began as a drizzle Aug. 6, shifted to downpours through last Thursday and eventually petered out by Saturday — varied several inches across Wake, Durham and Orange counties.
“This data really shows the value of citizen scientists in helping us better understand when and where rain falls during events like this,” said NC State climatologist Corey Davis .
“The National Weather Service can look at those totals to consider where the local flooding potential is the greatest. And for our state drought monitoring, those reports are also extremely useful to see which areas had enough rain to bring drought improvements, and who might have missed out.”
Even though Debby’s rain began on Aug. 6 in the Triangle, The News & Observer analyzed CoCoRaHS measurements from Aug. 7 to 11. The network’s observations are taken each morning, so you have to look at the following day (Aug. 7) to get accurate totals from the previous day (Aug. 6), NWS Raleigh meteorologist Tom Green told The N&O.
“The most rain we saw around the [Triangle] area was over 8 inches in Cumberland County near Fayetteville, while most of the Raleigh area saw 5 to 6 inches,” Green said.
Here are the five-day totals for Raleigh, Durham, Chapel Hill and surrounding towns beginning Aug. 7. The station names include the distance each rain gauge is from the center of the town/city it’s in with a compass direction.
But Davis is skeptical of this figure, since the lowest nearby total is 4.59 inches. He suspects the lowest seemingly accurate total is 3.95 inches in Wake Forest, near the Franklin County line, he said.
Reports show Cary/Apex got the most Debby rainfall
A Cary neighborhood received the most rainfall in Wake County, the network’s data shows, with 6.76 total inches across five days. The heavy rainfall was recorded near Green Level High School on Roberts Road.
Most CoCoRaHS observations Aug. 7-11 in Cary and Apex show between 5 and 6.5 inches of rain. The lowest amount was in Cary’s Stonehaven neighborhood with 4.72 inches.
CoCoRaHS measured the highest rainfall amount at 7.47 inches in northwest Durham’s West Hills neighborhood . The lowest amount was near the Bluffs of the Eno neighborhood (about seven miles north of downtown) with 3.5 inches.
Rural northern Orange County saw the county’s highest rainfall amount with 6.97 inches. Most CoCoRaHS observations Aug. 7-11 in Chapel Hill show between 4.5 and 6.5 inches of rain.
