The storm re-intensified into a tropical storm briefly again before making another landfall close to New York City. The storm was then quickly classified as an extra-tropical storm before recurving and looping, and then eventually dissipating across northern Pennsylvania.
The end result was extreme rainfall across the state with record flooding spawned by 8-10 inches of rain in some locations in a matter of four days.
Actually, the largest cause of damage from tropical cyclones is from inland flooding, and that can affect most everyone. Often this far inland, to get extreme rainfall, the storm has to stall or there is another factor to enhance the rain. If the tropical moisture of the storm mixes with a front, the rainfall can be enhanced. That is what happened with the flooding in our region in 2004.
Occasionally, we can also get some strong winds from the remnants of a tropical cyclone, like was the case of Sandy and from severe thunderstorms or tornadoes spawned by the system but that isn’t as likely as the rain.
These sensors are used to triangulate the lightning strikes with high accuracy. They send data to weather providers like what we use for our broadcast. Our computers can plot these strikes on a map and keep a tally the strikes within a certain area.
