We have been watching an additional now, Severe Thunderstorm Warnings in effect when we see Warnings Issued that is time to take action, most activity north of the city at present where we do have Severe Thunderstorm Warning for parts of the philadelphia county, sliver in Montgomery County, bucks county and burlington county, cell movinge at 30 miles an hour so impacting abington, bensalem, moving off to the east and impact florence. We have a Severe Thunderstorm Warning and now Tornado Warning for parts of the berks county, it looks like reading is included in that Tornado Warning right now, this cell moving east southe, continuing lightening right now as this cell is moving your way. Also dealing with heavy rainfall and strong wind potentially up to 16 miles an hour, we have previously had Severe Thunderstorm Warning for central berks county until 5 15. National Weather Service has just issued a Tornado Warning for parts of the central berks county until 5 30 so there is rotation being detected within this cell, right at this point would i imagine it is Doppler Radar indicated. I was seeing rotation in the cell in northampton count up as well. These cells do have the ability to have within them a spin of tornado, that will be along with the severe warning, strong, gusty winds, frequent lightening as well. We will look at this cell, Severe Thunderstorm Warning with this cell as well moving off to thee effecting west brad forward right now stretching off to thee at 30 miles an hour, this is Severe Thunderstorm Warning, for potential of 60 miles an hour wind in Chester County. Also keeping an eye on this cell, telling but in Northampton County showing signs of rotation, just a few minutes ago, weak rotation at that but we will keep an eye on this cell potentially that could see a Tornado Warning being issued as well what to expect as we head in the evening tonight . Strong to Severe Weather. We are seeing. That these storms will be rapidly developing and rapidly strengthening because we had that heat our atmosphere is primed, it is extremely unstable right now, so these cells that start to get going they are flaring up very quickly. You can go from no rain at all , sunny skies to dealing with a severe thunderstorm and 10 to 20 minutes time. Keep yourself weather aware as we head in the next several hours. Also dealing with the damaging wind threat isolated tornado threat, heavy rain threat all across the area we are seeing right now most of the activity north of the city but we could see activity flaring up south of the city as we head in the next couple hours. Should we go back to radar . We will go back over to the Weather Center so i can talk about the Tornado Warning, so i have to go take a step back over to the Weather Center and so i can unclick myself manning the Weather Center all along and now dealing with the Tornado Warning. Trying to multi task with you here. Will the storms linger. They will not linger but we will be dealing with this scattered, you know, scattered in coverage and rapidly strengthening, rapidly forming as well, so it is not going to stick around your neck of the wood. Not moving in a extremely fast clip in Forward Motion and 30 miles an hour which isnt necessarily slow. Slow moving cell we would say five, 10, 20 miles an hour fast moving cell would be moving at 50, 60, 70 miles an hour. The Cell Movement is between that but mostly concerned with the cell in berks county where we do have this now Tornado Warning in effect. You can see reading is included, were under this warning, cell is moving to the east way touch of southerly component to the motion there continuing lightening. Lets take this lightening off to get a better look at position here. You will see this bright reflectivity where we see bright red, purple, that is likely your most intense portion of the storm so right over berks county right now, leesport, center included in that, movement off to the east our concern in the maiden creek area, you need to seek safe shelter at this point. I will check these storm reports, there is reports from Chester County from the severe thunderstorm but no reports for berks county as this point tornado is radar indicated so radar showing some signs of rotation, that there could potentially be a tornado embedded, in this severe thunderstorm in berks county moving off to the east at 30 miles an hour. Cell is currently conditions or most potent part of the cell is just north of the reading area, and hey, lauren i will give a second. I know you have news. Give her a second to get all that information gathered but this is a Tornado Warning that is happening until 5 30 currently 5 13. In the bucks county or berks county, berks county area what you want to do is make sure you are away from windows, go to the interior portion of your house. What typically happens is the sky start to turn that green color and you see the atmosphere start to spin around and that is when you want to go inside and get out of these. We are letting lauren look at this information just coming in right now but this is happening, in berks county, and she was saying that this cell if you look right there it is the most intensely colored portion of that radar is where that most intense part of the storm was but this is radar indicated which means no one has had their eyes on it yet but that means that radar is picking up what is likely a tornado. We are trying to get any damage reports, certainly if you are in the berks county area, where you see that radar indicated tornadoinging through take shelter, go to the interior room in your home , go into a bathroom, that is the most safe places in these sorts of situations. This isnt a watch, thinks real deal thinks a warning, a watch means potential exist but this is happening. Correct, that is right, important to know difference. We had that severe thunderstorm watch in effect which means you need to keep an eye out keep yourself aware of the changing weather situation but when that warning is issued you need to take action in berks county we need to be taking action. You need to be on the low level of your home away from any windows. You want to have most walls around you. Basement if you dont have a basement and interior bathroom , interior closet, you want to put most walls around with you this strong wind threat. Even if we dont have a tornado on the ground we still have this potential to see very strong wind in excess of 60 to 70 miles an hour which can cause damage. You could see impacts from flying debris so you want to be positioned indoors away from the windows and also likely and pur line damage also likely with this very strong cell right new moving through berks county. I put a Storm Tracker, see Tornado Warning in effect until 5 30 in the towns here, fresh valley at 5 17. So really in the next two minutes. Sorry if i pronounce this name rust combmanor, owe lay at 5 29 and pine waters at 5 37 as this cell moves east at 30 miles an hour you say 60 to 07 miles an hour that is like a low grade hurricane, isnt it. Yeah, think bit in that context, ukee that is a great point. You think of hurricane strength. Tropical storm force strength is 39 miles an hour and that is where we start things out and thinking about Hurricane Force that is 74 miles an hour , so when you get up in that range 60 to 70 miles an hour that can do some serious damage tour property and could cause potentially personal injury to yourself, to your family, gets or live stock. We are talking about a Tornado Warning if you are just joining us issued by national Weather Service in central berks county is main focus right now accounts just north of the reading area you can see continuing lightening ongoing in and around that area likely torrential rain. This is radar indicated rotation. So no confirm nation of a tornado on the ground but does not mean it is not on the ground. That is how we want to treat this better safe than sorry. We will seek appropriate shelter because this Tornado Warning is in effect for the next 15 or so minutes, 10 to 15 minutes. Now this is Severe Weather warning or warning season is that correct. That is correct, for us as we head in the july month in particular in and around philadelphia area delaware valley, july is a very month where we see a lot of incidents of Severe Weather over last couple weeks we have had quite a few instances of Severe Weather. We had a tornado in delaware. We had two tornadoes in new jersey and now we are dealing with the Tornado Warning right now in berks county where we see that bright purple, bright red color that is most intense portion of this cell right now Doppler Radar indicated tornado. There is some tree damage, can you repeat that, in penn township some tree damage, potential power lines down in penn township. This cell does not have a history of producing, damage with strong wind. You need to seek safe shelter because of this moving through berks county area just north of reading, zoom in as far
