We’ll see how long this deformation like area rests over Atlanta, but looks like S side of town is over 10”. Models did hint at this due to the interaction with the ULL. 

It should be done in an hour or 90 minutes as the system lifts out the dynamics weaken and this is also a bit of a downslope direction

Helen continues to bring prolific rainfall. As of 7:25 am, Atlanta has 3.22" of rain today. Today is the third consecutive day with 3" or more rain. That breaks the record of 2 days set during December 8-9, 1919 and tied during July 4-5, 1994. The three-day total rainfall is 10.96".

BULLETIN - EAS ACTIVATION REQUESTED
Flash Flood Warning
National Weather Service Greenville-Spartanburg SC
717 AM EDT Fri Sep 27 2024

...FLASH FLOOD EMERGENCY FOR PICKENS AND OCONEE COUNTIES...

The National Weather Service in Greenville-Spartanburg has extended
the

* Flash Flood Warning for...
  Oconee County in upstate South Carolina...
  Pickens County in upstate South Carolina...

* Until 430 PM EDT Friday.

* At 717 AM EDT, emergency management reported hundreds of trees
  down preventing rescue operations. Shelter in place and do not
  travel unless fleeing floodwaters. Significant flooding is ongoing
  in multiple locations, resulting in road closures, first-floor
  inundation, and damage to some structures.  The risk of
  life-threatening landslide activity continues to increase in the
  South Carolina mountains. Between 5 and 8 inches of rain have
  fallen. The expected rainfall rate is 1.5 to 2.5 inches in 1 hour.

  This is a FLASH FLOOD EMERGENCY for Pickens and Oconee Counties.
  This is a PARTICULARLY DANGEROUS SITUATION. SEEK HIGHER GROUND NOW!

  HAZARD...Life threatening flash flooding. Heavy rain producing
           flash flooding.

  SOURCE...Emergency management reported.

  IMPACT...Life threatening flash flooding of creeks and streams,
           urban areas, highways, streets and underpasses.
           Extensive flooding of homes and businesses.
           Widespread road closures.  Widespread life-threatening
           landslide activity.

* Some locations that will experience flash flooding include...
  Easley, Clemson, Seneca, Walhalla, Pickens, West Greenville,
  Welcome, Central, Pendleton, Liberty, Westminster, Gumlog, Norris,
  Six Mile, Tallulah Falls, Salem, Lake Keowee, Keowee Toxaway State
  Park, Devils Fork State Park and Lake Jocassee.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Move to higher ground now! This is an extremely dangerous and
life-threatening situation. Do not attempt to travel unless you are
fleeing an area subject to flooding or under an evacuation order.

Heavy rain is significantly increasing the risk of landslides,
especially in areas where slides have occurred in the past. Slides
can destroy single homes and other structures and large sections of
roads. If you are in the warned area, you should not travel, except
to move away from flash flood or landslide dangers. If you are in
the vicinity of a stream near the heavy rainfall, especially on a
mountainside, or at the base of a mountain or in a cove, move
immediately to a safer location.

Turn around, don`t drown when encountering flooded roads. Most flood
deaths occur in vehicles.

In hilly terrain there are hundreds of low water crossings which are
potentially dangerous in heavy rain. Do not attempt to cross flooded
roads. Find an alternate route.

First spot of 30” based on radar estimates*

IMG_4222.png

Can't say I've ever seen radar estimates like that before ever! Wow

 

And even if you were to cut that total in say half it's still 15 inches!  

 

Poor southeast!

Pretty shocking that SC has surpassed GA in outages

Screenshot_2024-09-27-08-03-45-485.jpg

GA I think had more in Irma and Zeta, about 1.2 and 1.1  but that was sort of skewed by the fact ATL metro was impacted, this time they likely account for under 200K of those outages
