Major Flooding Reported

9:45PM UPDATE: The rain in Pennsylvania has still not turned east and is making me very nervous. The rain is as far north as I-80 in Central Pennsylvania. I unfortunately will not be able to update again until after after 12:30am. I will post a quick update at the time though.

The back edge of the rain shield is beginning to move through the Grotonweather tri-county area and will continue to do so over the next hour or so. Rainfall totals are over 3" over most of the area, and radar estimates max out at 4-5" over southern Cortland County. In all honesty though, it appears the radar is under estimating the precipitation, so I would not be surprised if places like Marathon got even more.

As I have been saying, if these rainfall amounts occurred in our area, the ground would not be able to handle it. Unfortunately, that prediction has come true. Here are a couple of the flooding reports I have heard so far, all from Cortland County:
  • Route 11 between Reagen Road and Hoxie Gorge Road is CLOSED due to a mudslide
  • Other mudslides have also been reported
  • In Homer: The Haights Gulf Bridge is out.
  • In McGraw: Roads IMPASSABLE throughout the village
  • Red Cross Shelter for evacuees in the gymnasium at the County Office Building
I have not heard of any flood reports in Tompkins or Cayuga Counties, but that does not mean it is not occurring. I cannot stress enough, never drive through flooded roadways!! There are roads underwater in the area. DO NOT attempt to cross the flood waters. Doing so may put your life in jeopardy. If you are told to evacuate your home, do so!

As I stated at the start, the rain is ending. However, this does not mean the flood threat is ending! Runoff will continue to create flood problems into tomorrow. Area rivers are not expected to reach their peak heights until about this time Friday.

There may be some additional rain tonight. What is left of Tropical Storm Nicole is moving up through North Carolina and Virginia currently. The models have consistently kept this rain off to our east tonight. However, the fact that the models were too far east with today's storm, and the fact that the radar from that region looks very much like it did last night (namely a large area of rain seemingly heading right at us) has me a little nervous. I should stress, though, that we are not in the same sort of set up now, and, thankfully, I do see indications in the upper atmosphere that this rain will turn to our east, as the models indicate. If the models were wrong, which I do not think they are, and we were to get another couple inches of rain tonight, it would be disastrous. Again, I do not think this will be the case.

In summary...the rain may be ending, but the flooding will continue into tomorrow. Stay safe!!!!
