A Particularly Dangerous Situation (PDS) is a term used in rare situations when long-lived, strong and violent tornadoes are possible. A PDS can also accompany severe thunderstorm watches for intense convective wind storms, according to the National Weather Service (NWS).
"Storm development can be extremely explosive," according to AccuWeather expert Senior Meteorologist, Dan Kottlowski. "Tornadoes can be longer lived and larger than normal."
According to the NWS, these storms can be accompanied by several intense tornadoes, damaging wind gusts possibly up to 80 miles per hour and perhaps, hail up to 3 inches in diameter.
"In this case, if they issue a warning, I'd head straight to your basement or shelter," said Kottlowski.
This phenomena is scarcely issued by the NWS. It is of utmost importance to heed shelter as soon as possible.
