The National Weather Service has included Cobb County in a flash flood watch until Wednesday morning due to rains stemming from Subtropical Storm Alberto.
The watch was to begin at 2 p.m. Monday and covers most of north and central Georgia. The heavy rains could cause flooding in rivers, lakes, streams and other low-lying areas.
Alberto was making landfall on the northwest Florida Gulf Coast early Monday afternoon, according to the NWS, which also included this information in its watch alert:
Subtropical storm Alberto will continue northward into eastern Alabama through this evening bringing abundant moisture and rainfall along and east of its track. This will allow for increased rainfall potential across the area. Although average rainfall totals will average 2 to 3 inches, some areas could see as much as 4 to 5 inches through Tuesday night. Creek and river levels are already above average and will not take much additional rainfall to cause levels to rise above bankfull.
Several creeks and rivers will rise out of their banks closing roads and impacting homes, businesses and farms. High water may not recede until well after the rain has ended.
The chance of rain in Cobb and metro Atlanta is expected to increase later on Monday afternoon and overnight and through Tuesday, possibly up to a 90 percent chance. We could get up to three-quarters of an inch of rain Tuesday night.
In addition to the rain and possible flash floods, foggy conditions may also be present.
The watch period ends at 8 a.m. Wednesday.
On Wednesday, thunderstorms are likely, especially on Wednesday evening, with the chance of storms tapering off as the week continues.
High temperatures Monday and Tuesday will be in the high 70s and lows in the high 60s. From Wednesday through Thursdays, highs could reach into the mid-to-high 80s with lows in the low 70s.
Sunny skies are not expected to return until Saturday.
