I had the pleasure of visiting my mom on this day during when the storm hit. She lives in East Islip – the town just to the west of Great River.
It started out as just a very heavy rain storm. She in fact picked up just under 3” of rain in 45 minutes! There wasn’t too much wind at first and moderate TRW. But then towards the end (around the time to tornado hit – approx 2pm) the wind picked up noticeably and it looked like a monsoon outside!
I also took some video. I can’t remember if it was during the windy part or not. If it was I’ll post that as well.
The heavy rains in a short period of time resulted in some water going into my mom’s basement which only happens when a lot of rain falls in a short period of time – as is evident in the photos.
I drove around Great River around 7pm. I only noticed damage on the street mentioned in the bulletin below. I also drove north up Ocean avenue and didn’t see too much – just some branches down here and there. But I didn’t go into the state park – it was already closed for the day .
