bluewave Posted April 30, 2014 Share Posted April 30, 2014 there is plenty of rain to come on radar and more will probably develop as the warm front passes and we get unstable aloft We have seen some of the steepest mid-level lapse rates from January to April that I can remember this year.

gravitylover Posted April 30, 2014 Share Posted April 30, 2014 What about the day Hurricane Irene hit? Or Hurricane Floyd. Oooh Hurricane Floyd (TS by the time it got here if I remember correctly) was incredible. There were places in the Taconics and Hudson Highlands that got 14+" of rain in one afternoon. I had a 5 gallon bucket outside my basement door in a wind protected area and it was overflowing by the time the sun set that day. I actually had to open my store that morning in Patterson because I was expecting deliveries and by the time I left around 3 it was coming down in buckets. There were a few times I had to come to a complete stop in the middle of Rt 22 because I couldn't even see the end of the hood and there were places the water was running nearly hood deep across the road on the hill up to my house and it was just cross the fingers and gun it. We lost entire hillsides in the woods and the creek that drains the area where I mt bike was fifteen feet deep in a few spots where downed trees temporarily dammed it up. When it was over there were blocked up valleys and piles of downed trees twenty feet high at the bends in the creek. I thought when I saw 11" of rain in an afternoon in Cordova AK that I would never see anything like that again but Floyd was a whole new type of awesome.
