Live | Tracking severe thunderstorm warnings across metro Atlanta

[Music] oh [Music] [Music] [Music] oh [Music] oh [Music] oh [Music] [Applause] [Music] oh n [Music] oh [Music] [Applause] [Music] Thursday evening showers and STS have returned to North Georgia and these are pulsing up and becoming strong and severe we don't have a lot of storms on the map but the storms that have developed they have become intense in fact in the last 20 minutes we have reports of half dollar siiz hail in alphareta Also that large hail in Roswell as well and this is all within a severe thunderstorm warning which is for parts of Cherokee County Southeastern Cherokee County that northern part of fton County including Alpharetta down to Roswell and also Northeastern Cobb County so that warning is going to go until 9:30 tonight I'm Meteorologist Melissa Norton for Chris Hulen with your weather impact team and this thunderstorm is one of several that we have on the north side of the metro and these all developed after another thunderstorm kind of collaps that was in Walton County earlier that also caused damage and I want to show you the damage from Walton County Sam if we can take this full look at this this is from 11 live viewer Abby Brooks you can see multiple trees snapped over in Monroe County H in Monroe rather in Walton County and Walton County Emergency Management are reporting that we have three to four structures in the county that were damaged at one point there were about 3,000 customers without power between the EMC and Georgia Power customers within Walton County you can see these trees were snapped in half and many roadways were blocked by Fallen trees but that was earlier tonight about 2 hours earlier now we are focused on the storms on the Northern side of the metro area and these thunderstorms producing some 60 MPH damaging winds and also hail so I want to what I want to do right now I know it's kind of hard to see this um on the map I'm going to take some of that fuzziness out of the radar image and what I want to show you is where the core of this storm is I'm going to put on a mode of the radar that we call velocity and this helps us track When Storms are pulsing up and pulsing down they actually just Trimm that warning back a little bit but that storm was really intense right between alfaretta and Roswell and it looks like it's kind of on its way collapsing down right now so still the potential for Hail um the emergency manager in Fulton County as well was reporting hail near the Roswell area we had several reports from train spotters of half dollar size so about 1 and a/4 in size hail there that was in Alpharetta on kind of the western side of Alpharetta and now that storm is centered over the western side of Alpharetta down to Roswell right along Georgia 400 we're also seeing as we zoom out a little bit we don't have any warnings on it but we've got more of these Areas with heavy rainfall throughout portions of Cobb County as well we'll fix the radar again for you so it's easier to see um you can see in downtown maretta all along the 120 Loop we have heavy rain and lightning also as you travel up into Northwestern cob County and Southwestern Cherokee County and Barto County we've also got some Aries of heavy rain and lightning there so again this is one severe thunderstorm warning still in effect this is going to run until 9:30 this evening this is for parts of fton County and also Southeastern Cherokee County and as well as Northeastern Cobb County until 9:30 so that storm these are pulse thunderstorms they're not like a line of thunderstorms we call them pulse storms because they have one updraft one down draft sometimes these storms in the summer they intensify really quickly we see the lightning counts going up on them and as they're collapsing they'll drop strong winds that's how we get these downburst winds in the summertime and sometimes as they're pulsing up we also get hail so these storms that have very tall updrafts the hail keeps getting cycled in them for longer more times up and down the thunderstorm and so the strongest of thunderstorms the tallest thunderstorm uh tops that's where we start to see the larger hail a lot of our 11 alive weather impact team members on Facebook are also commenting what they're seeing out there Heath Harvey started off in John's Creek um about an hour ago with psize hail and then that hail actually grew in size also Nicole U marsten Down in duth was saying there's lots of rain that was coming down there and we just got a video as well in from Lawrenceville I'm going to try to get this up here in a few minutes for you but a lot of lightning and heavy rain in lawrencville and also in Roswell they were getting Dory Griggs was one of our 111 weather impact team members and she was also seeing some of that Heavy Rain the hail the lightning in Roswell um so again just recapping we have this severe thunderstorm warning uh Nichol siiz hail according to the emergency manager in fton County Shane far gski uh nickolai hail at fire station 25 that's in Roswell off of Hur Road also several trees down and if you guys can hear me in The Newsroom I'm going to read out some trees down locations if we can send a photojournalist uh House Road there is a tree down as well on East Creek Circle those are both I think in the Roswell area so reports of not just the hail but trees down in the Roswell Community as well um I will check the Georgia Power outage map we're just kind of tracking this live as we're on 11 alive plus and 11 alive on the app the Georgia Power outage numbers we're not seeing a lot coming in yet but they've just started coming in from kind of Northern Fulton County looks like in between between Milton and Roswell we have about 500 customers without power in alfaretta we have over 1,700 customers without power um and it looks like those outages kind of stop as you get south of Roswell into Dunwoody we're not seeing as many power outages there couple near John's Creek Pete street corners but those are less than 100 people and the earlier power outages that we saw the big numbers about 3,000 without power in Walton County a lot of those are uh restored but still about 1,200 customers without power near Social Circle so that's kind of in between Southwestern Walton County and also Northeastern Newton County where we had that earlier severe thunderstorm so we still have several uh thousand people likely without power and the core of these that are over the north side of Atlanta about 1,700 customers without power in the western side of Alpharetta down through Roswell so some people are dealing with power outages because of those down trees the down likely a couple of down power lines as well and then the large hail that we were seeing I'm going to put them mode of the radar on that we can look at the hail this is the let's see this is a hail size mode not seeing a lot of hail size right now let's see if we can get our hail tracks to come up from the last hour my service there we go you see this okay this is you can see where it pulsed up so this takes us through a history timeline of the hail size within this thunderstorm you see how the hail in John's Creek wasn't very big but then as that storm moved into the western part of John's Creek and Alpharetta it really just pulsed up and I'm going to query a couple of these numbers so that you can see uh the hail size there between wests side Parkway and kind of the south side of alfaretta oo estimated this is radar estimated so not confirmed but radar estimated sizes of nearly 2 in in diameter so when we talk about hail sizes we have a whole chart and we get to kind of nickel siiz hail that's less than an inch so it's not severe warn criteria but when you get up to quarter size so that's about an inch in diameter that's where we start to see severe uh warn thunderstorms the half doll size hail that we were getting confirmed earlier that's about an inch and a quarter then we get up to pingpong ball size hail which is about this it's about an inch and 1.75 in we get up to pingpong ball siiz hail and that's what we were seeing near Manel Road and uh hanbridge Road this is the radar estimated so they're trying try to estimate it was closer to 2 in which would be about hen egg size but I mean who really knows what a hen egg looks like in diameter best thing to do if you have a hail report take the hail and put it in your freezer after the hail's done when you measure it you want to measure it with a ruler so don't just put the hail on the palm on your hand and say this is how large it was everybody's hand is a different size so when we're talking about hail sizes the best thing is is to put it next to something with a reference point so if you have a ruler that's great because we can get a really exact measurement but you you heard me say quarter size nickel size uh half dollar size those are the kind of put it next to a pingpong ball or a golf ball uh and those are the better markers for us to know how big exactly the hail was rather than just the size of your your um hand so again we had large hail the severe thunderstorm warning continues until 9:30 this evening it's for parts of Northern fton County cob County as well as Cherokee County and the earlier severe thunderstorm warning in Walton County that's been expired for quite a while so we've got that we've also got a new thunderstorm that's kind of pulsing up if you will in Northwestern Cobb County and that one between Emerson aworth and kind of the western side of Kennesaw through marsill Road up through alauna high school and that again it doesn't have a severe thunderstorm warning on it but as these storms pulse up even if they don't have a warning we can have some of those wind gusts around 40 to 50 milph at most um and so that that is an indicator of a strong storm that's not necessarily reaching that severe criteria again it looks like the hail threat is kind of coming down a lot and that's great but we did have some earlier confirmed hail that was half dollar size but again the severe thunderstorm warning is kind of for Northeastern Cobb County Northern Al uh Fon County near alfaretta between Roswell and alfaretta and that Northeastern little section of Cherokee County East of Woodstock so kind of along Highway 92 there but we're also seeing the thunderstorms that are pulsing up there in BTO County and Cherokee County um I'm in my chat room and I'm looking through I get information from emergency managers the National Weather Service we also have our 11 alive weather impact team Community as well um and I I really appreciate everybody that sends those reports because that helps all of us track these thunderstorms better um but we did get an earlier video in I showed you a few minutes ago I'll show it to you again this is from the storm earlier in Walton County in Monroe the trees snapped in half um so these thunderstorms a lot of these we typically see in the summertime calming down around Sunset we lose that daytime Heating and they calm down but these kind of just started getting going around Sunset because we had these little outflow boundaries from thunderstorms so these should last another hour maybe two hours at the most I would hope that they'll be kind of calming down by 11 o'clock tonight and then we'll focus on more storm threats on the way for tomorrow and I just want to briefly touch on the holiday weekend forecast while we're talking about the severe thunderstorm that's here now because notice each and every day Friday Saturday Sunday Monday each of those days there's an opportunity for more thunderstorms but none of those days show you 100% chance of rain what that means is kind of like what we're seeing right now the coverage of the rain the coverage of the thunderstorms is going to be pretty limited but when we see these storms developing with it still being hot and humid outside we can see a few of these storms that turn strong maybe even turn severe and tomorrow again there's another opportunity for a couple of those stronger storms this is the Outlook From The Storm Prediction Center for Friday afternoon and evening so that bold kelly green color on the map Athens all the way up into Dela Helen if you're going to be kind of shooting the hooch up there and up through Northeast Georgia that's a level one threat of severe weather so just like today not every Storm's going to be severe but we have enough heat and humidity out there that we'll see the potential for maybe a stray shower thunderstorm that turn severe like we've seen this evening let me show you a forecast track because today's rounds of round of storms will be quiting down we've got another one we're dealing with tomorrow we will start the day mostly muggy and really mild we're going to quickly heat up to around 90 and then as we get into the afternoon we're in the 90s and here we go we get these hitter Miss showers and storms developing they will continue through Sunset and then they'll start to calm down so couple of these could still be ongoing as we have high school football games beginning Saturday morning looks like a dry start so if you're going to be out tailgating before the Georgia Clemson game things look mostly dry but again in the afternoon showers and storms develop I think most of these are going to be done by Sunset but I don't want to say that it's dral together so if you're heading to the Georgia state and Georgia Tech game in the evening it is again possible that there could be a shower or storm impacting you um National Weather Service just continuing this special weather statement that is for the 40 mph wind and cob Barto ping counties um and the severe thunderstorm warning will be expiring here at 930 another thing I want to mention which I don't think we mentioned at the beginning here we tied today's record high in Atlanta yes let me get up the almanac uh we tied the record high of 98 Degrees from 1990 we're waiting on the official climate report to come out after midnight tonight but this was our record for the day I mean we were saying all week how would be very hot Wednesday and Thursday we hit 97 yesterday today 98 so that would tie if that stands which it should stand it ties our daily record for the day of uh 98 from 1990 so that is a 34y old record that is tied today and this rain is coming on the heels of a developing drought situation our drought monitor that came out today brought in again a moderate drought to parts of North Georgia in Atlanta itself at the airport we picked up 77 in of rain this entire month uh I'll pull that graphic up for you we're on if today the month of August ended it would be the third driest August on record for us so we've got a rain deficit of over 3 in I'll step to the other side of the screen so you can see a little bit better we've got a rain deficit of over 3 in here for the month of August in Atlanta so it's been really dry but here today all the way through the weekend it's these pop-up thunderstorms that we'll be seeing that hopefully add a little bit more rain to that rain number so again just recapping we're going to wrap up this uh live broadcast on 11 live plus and 11 live here shortly this thunderstorm luckily has weakened um I I wouldn't be surprised if they in fact end it early the thunderstorm warning but the storm really pulsed up over Alpharetta and Roswell and we saw we have confirmed reports of half doll size hail and I'll show you where those hail trackers happened you see that big purple on the map this is our estimated hail size what it was so this was over hanbridge Road Old Alabama Road uh Manel Road right along Georgia 400 these were hail sizes that were um over you know this is estimated radar estimated close to 2 in in diameter which when you get above golf ball okay when you get to golf ball size hail which this is just above golf ball you see dents of the cars you can see car windshields that have cra CS in them I don't know if it actually got this large but when we get to quarter size we don't see a lot of damage when it gets up above half doll size that's big hail for around here at least we're not in the middle of the plane so when it gets close to 2 Ines in diameter we start to see a lot of damage um so that storm pulsed up really quickly it is now pulsed down but that is what our news team is working on Gathering more information about reports of hail reports of trees down and power outages again we have about 1,700 customers without power in Alpharetta from Georgia power we also have about 500 customers kind of on the south side of Roswell who are without power right now couple of trees down trees down in Roswell um on House Road East Creek Circle Road and we also have several trees that were down in Walton County as well as the storms moved in earlier so again we are tracking this thunderstorm the warning is going to be expiring here shortly I haven't gotten word if they're going to oh yep good so I was just saying I wouldn't be surprised if they expired quickly and just came out just came out at 9:23 they're going to expire the warning at 9:30 the storm has pulsed down it's really weakening but we still have a couple of heavy rain producers and thunderstorms in the western part of we'll go back to the normal radar so we can see that so that's where the hail was earlier that warning is going to be expiring and we still have some heavy rain throughout Eastern Barto County Western Cherokee County Northwestern Cobb County and also right over the 120 Loop there in marota we're still tracking some locally heavy rainfall hopefully we will not see any more of these turn severe uh but we are on it we have a news crew heading to alphara where there were the reports of trees down and large hail we'll bring you all of that live coming up on the news at 11:00 on 11 live in WL for now meteorologist FIS nor with the 11 alive weather impact team tracking these thunderstorms the heat all of that for the weekend if you want to know more about our impact
