UPDATE: Heavy Storms Flood Some Areas

Flash flooding in Daleville in Botetourt County from Allison Whitlow.

UPDATE: 4:05 p.m.

Lynchburg, VA - High winds knocked out power to some in our area Sunday, while other areas were flooded yet again in the Roanoke Valley.

Storms have already developing into a cluster moving east into Southside Virginia with another in the NRV.

Other storms have popped up at random Sunday afternoon.

All of the storms are capable of torrential downpours and strong wind as they move through.

In Botetourt County, ABC 13 Viewer Allison Whitlow took several pictures of high water and flash flooding in Daleville around 2 p.m.

In fact, Appalachian Power reports 2,589 people without power from the storms.

At ABC 13, our station continues to take several hard power hits, causing our broadcasting equipment to reset. If you have lost our signal, please be patient... it should return shortly.

As we head into Sunday night, storms may continue for a few more hours before dying off with the loss of heat from the sun.

Temperatures aren't expected to be quite as hot as they were last week, but with plenty of moisture in the air, it will not take much heat to get mainly afternoon and evening storms going well into the week ahead.

When we get into a stagnant, summer pattern, where the humidity and heat just sit around everyday, the "pop-up" storms can turn severe in a hurry. They use the heat from below and can drop hail and create damaging winds for only a few minutes before raining themselves out.

We call these storms "pulse" storms, because of how quickly they flare up and then fade (much like a pulse).

If you get under one of the storms over the next several days, remember to get indoors and away from windows if you can.

If you are outside and can hear thunder, you are close enough to being struck by lightning. Get inside and wait 30 minutes for no thunder before going back out.

You can determine how close a lightning strike is to your location by some simple math, actually. After you see the flash, count the number of seconds it takes before you hear the thunder. Then, divide that number by five, and you get the number of miles the lightning is from you!

It is often mistakenly thought that you simply count the number of seconds in between the thunder and lightning, but you actually have to divide by five.

For example, if it takes five seconds for you to hear thunder after seeing lightning, the storm isn't five miles away, it's only one mile away!
