Daily rain could raise flooding risk by weekend

Overnight showers dumped about an inch of rain across parts of metro Atlanta, and with rain likely each day this week, forecasters are warning of a risk of flooding later in the week.

Rainfall totals just before daybreak Tuesday included 1.15 inches in Alpharetta, .90 inch in Marietta, .85 inch in Dunwoody and .66 inch in Chamblee. Hartsfield-Jackson Atlanta International Airport reported .31 inch.

Channel 2 meteorologist Karen Minton is predicting a 70 percent chance of rain Tuesday and Wednesday, diminishing only slightly to 60 percent for Thursday through Sunday.

In addition to the showers, “there is a chance of thunderstorms each day as a persistent wet and unsettled pattern affects north and central Georgia through this weekend,” the National Weather Service said in a statement.

“Multiple rounds of showers and thunderstorms, especially Wednesday and Thursday, will produce an additional 1 to 3 inches of rainfall over saturated grounds,” the Weather Service said. “This will increase the flood potential through the week.”

Minton said highs near 80 degrees Tuesday will be followed by highs in the mid-70s on Wednesday. Highs will be around 63 on Thursday, 71 Friday, 76 Saturday and 73 Sunday, Minton said. She said morning lows in the low 60s early Wednesday and this weekend will book-end lows in the low to mid-50s on Thursday and Friday.

Atlanta’s normal high for mid-April is 72, the normal low 51.
