Central PA...February ends, March begins...


Recommended Posts

Sorta looks like that snow region was concentrated in southeast Cambria/Northeast Somerset by looks of most of the reports. I wonder what the top of Blue Knob looked like.

Not sure about there. But we have video tonight at 10 and 11 of the snow in ogletown. They ended up with around 6"

More areas could see that on Friday and Saturday morning with the comma head/deformation band.

0z nam trims the rain a bit thanks to convection in the deep south and Florida. Good news for the eastern half of the state. totals now are around 1.75" from tonight through tomorrow night. Higher amounts are possible near the NJ border.

Picked up about 0.33 of precipitation over night. The 2 major creeks for me are Pine Creek and Lycoming Creek

Pine Creek at Cedar Run picked up about an 1.00 of rain over night. And Lycoming creek picked up from 0.36 to 0.52"

And so far they haven't started rising.

It appears the heavy rain is going to stay further to the east.

Local creeks were up a bit this AM on the way to work but not by much. CTP makes mention of a dry slot lull. Looking at the radar, Virginia and on a line to the southwest is mostly rain free at the moment. That's encouraging for the flood prone areas. Latest crest forecast at Marietta is 53.8 ft and the major flood level is 54.0. If that forecast holds, that would make this a top 10 event for that location.

And to think the Agnes crest was a full 10 feet above the current forecast. What a ridiculous event that was.

I was only a youngin, but remember it like it was yesterday the scenes are etched in my memory. I think a major contributaing factor why i like severe weather.

Hopefully Agnes was a once in a lifetime event!

I went through that flood. Had 2' of water on the first floor of my parents house.

The river was rising about 1 1/2 feet an hour. And it didn't stop rising.

Back then they blew the fire siren when the river went over it's banks.

Hehehe...hear the siren blow around midnight get up the next morning to find the river about 1/2 block away. And I lived over 1/2 mile away from the river.Was unreal!!

Our house won't flood*.

*Said with a grain of salt, but even in '72 the land our house sits on wasn't under water at all. It never got above 3rd and Hamilton - that's actually a high point in the city and kind of a plateau between 3-5 and Reilly and Macklay. Either sides of that little area it drops off quickly.

New forecast for the Susquehanna in Harrisburg is 20' - that's to the level of flooding out quite a few homes in the city. And the Yellow Breaches in New Cumberland will be roaring (it is easily flood prone) and unfortunately there are entire neighborhoods that will be flooded out. It's a normal occurrence there it seems.

I was also just a wee lad in '72. We lived along the Little Conestoga. I remember there was a produce market a few miles upstream that was flooded. There was all this fruit floating by. My brother was wading out and must have snagged over a 50 piece assortment. Weird the stuff you remember. And we had over 6' of water in the basement. The mud sediment crap that was left over after the water receded was rude to say the least.

I remeber Agnes.... the river was moving so fast and so deep that it would have been suicide to be near it. ALso the worse part was how quickly it filled in the valley when the levees broke.

I had just turned 5. I remember being terrified because I heard on the news a guy in York died because he stepped in a manhole crossing a flooded street and was swept away.

Our house on the northern end of the city is on a little elevation on our two-house street. If you are familiar with York, Kiwanis Lake and Willis Run flooded but the water came to just a block away (I grew up two blocks from it next to the projects).

My aunt had to be evaced out in West York. Water was steadily rising in her basement and she had to get out in a boat. Her street was a river, and she remembered people's possessions floating away past the boat.

Interesting aside, rain changed to sleet at Philipsburg at the end of it.

1.35" so far here. Can't remember ever seeing so much standing/flowing water after only that much rain. Our yard suggests we had like 3-4". Looks like another heavy batch about to move in from York County and northern Maryland.

Currently 53.1° with a southeast wind around 10-15mph. There have been some decent gusts as well. Moderate rain, getting heavier as I type.
