Depending on the season, flooding, lightning, thunderstorms, tornados, excessive heat, drought and winter storms can pose a threat to you and your family.
The National Fire Protection Association provides resources and tips on how you and your family can prepare for weather emergencies.
Watch vs. Warning
According to the National Oceanic and Atmospheric Administration (NOAA), a severe thunderstorm watch means that the potential exists for the development of thunderstorms which may produce large hail or damaging winds. When a watch is issued, you can go about normal activities, but should pay attention to the radio, Internet or TV for severe weather updates.
A severe thunderstorm warning means that a severe thunderstorm is occurring or is imminent based on Doppler radar information, according to NOAA. You should move indoors to a place of safety.
NOAA also states that a tornado watch, similar to a severe thunderstorm watch, means that conditions are favorable for severe thunderstorms to form and may be capable of producing a tornado. A tornado warning means a tornado is either occurring or imminent based on radar. You should take cover immediately.
Lightning Safety in Johns Creek
Thanks to lightning prediction devices and sirens at Ocee and Newtown parks, Johns Creek park patrons have advanced warning of possible lightning strikes.
The devices monitor the atmosphere's electrostatic energy up to 15 miles away and evaluate the potential for lightning within a 2-mile radius. When conditions seem favorable to lightning, a siren sounds for 15 seconds and a strobe flashes. The sirens may sound periodically if conditions persist. When conditions are no longer threatening, the siren sounds three blasts of five seconds each to signal all clear.
To learn what to do in a thunderstorm, read about lightning safety from the National Weather Service.
