Tornadoes, thunderstorms, and flash floods.
They're among the most violent storms Mother Nature can throw at us.
Action News Reporter Julianne Sweeney joins us Live outside our studio in Johnson City to tell us how the National Weather Service wants you to prepare for severe weather season.
The weather is calm right now.
But as head into summer, we'll enter severe weather season.
And these gray clouds behind me could turn more menacing and destructive.
"Weather happens 24/7. So it happens when you sleep, it happens on weekends, it happens during the week." said National Weather Service Meteorologist Erik Heden.
Severe weather can strike at any time.
That's why Meteorologist Erik Heden of the National Weather Service is urging people to have an emergency plan in place.
He's working to educate people during National Severe Weather Week.
"You really need that week to educate the public and it is a real hazard because people do die from tornadoes and flash flooding." said National Weather Service Hydrologist Mike Shaffner.
Tornadoes, thunderstorms, and flash floods are all classified as severe weather.
The Weather Service issues warnings about approaching or current storms.
The warnings are announced on local radio and television.
And also on this NOAA weather radio alarm that people can buy.
It should be turned on during times you may not be paying attention to the weather.
"Especially at night when you may not be expecting a flash flood or a tornado, obviously if you're sleeping...you're not really aware of what's happening in terms of the weather." said Shaffner.
When a warning is issued, the Weather Service encourages people to follow their plans to evacuate or seek shelter.
"So you know where to go, where should you go in your home, where should you go if you're at school, place of business." said Heden.
As a part of Severe Weather Week, the Weather Service will conduct an emergency practice drill this Thursday.
It's happening at 1:15-pm.
The practice warning will be announced right here on WBNG.
