HERMITAGE, Pa. (WKBN) – A National Weather Service official in Pittsburgh confirmed Tuesday that they did not send a warning of any kind before Sunday’s tornado in Hermitage.
According to the official, the NWS did not send either a thunderstorm warning or a tornado warning before the storm hit. The NWS determined that the storm was a tornado on Monday.
The NWS said a number of factors led to the decision to not send a warning. They said weak tornadoes are hard to see on radar and Sunday’s storms were more isolated than widespread.
Winds from the storm tore the canopy off a gas pump island at a service station in town, as well as snapping a number of trees.
The National Weather Service plans to use this situation to help them to better detect severe weather in the future.
Tornado threats in Western Pennsylvania and Eastern Ohio are most common in May and June. The National Weather Service’s Pittsburgh office issues about 10 tornado warnings a year and sees about four to six tornadoes form in its coverage area.
