Alberto’s outer bands will continue to bring brief torrential rainfall and significant winds. This will lead to more flash flooding and the threat of isolated weak spin-up tornadoes but that now is not too impressive.
Rain and wind continues to be the main threat…Around 3am the center of circulation will be near or over Montgomery, taking a slight jog towards the northwest.
Moving north and weakening over land Alberto will soon be downgraded to a depression and remnants by sunrise. The window for heavy rainfall and flash flooding is more concentrated along the path and little instability around the center of circulation. This will lead to brief gusts to 35 mph and saturated grounds may still be a factor but a weak spin-up tornado is only minor at this time. We may see the worst of this out of the region by morning.
Winds and a few toppled trees and small tree branches will snap-off easily, with 20 30 mph sustained and occasional gusts under 40 mph.
Saturated soils and small streams will fill quickly adding to more localized flash flooding in those low lying areas. Rushing water over intersections will also make for treacherous travel.
*Thankfully this is nothing like Alberto of July 1994 nor does it have the same large scale energy as Irma on September 11, 2017. That was a slower moving system (depression), which posed more significant wind damage across the region by an entirely different set-up.
