No big changes for Atlanta…

For perspective on wind… A thunderstorm in Atlanta is considered STRONG with winds of 40 mph. A thunderstorm is considered to be SEVERE with winds at 58 mph or more.

Opal in 1995 had 80mph winds and 5-7 inches of rain.

Lightest winds far northwest. Otherwise E/NE winds 15-30 mph in many areas, But gusting in some spots to 50 mph or more at times. The rain squalls on/off diminishing from south to north overnight, down to under 30 mph after 10 Tuesday morning, with the rain chance dropping to 40% late Tuesday afternoon. Additional rainfall one inch or so, with isolated 2 inch amounts.

I will edit, update and add to this blog throughout Monday/Tuesday, check back.

“Tropical Storm” force winds are defined as sustained at 39 mph or greater.

That’s a lot of water over Georgia:

3.3 Trillion gallons of more water projected to fall on Georgia over a 48 hour period

HAZARDOUS WINDS are expected to spread across much of Georgia, South Carolina and Alabama Monday and Monday night. It takes several hours to reset a power pole that has been knocked down.

Wind gusts over 60 will be the exception:
