lrene's Heavy Rain Impacts in PHL 8/29 - 8/31

The biggest implication of this storm potential is the Chesapeake and Delaware Bays backing up water into the inflowing rivers to the bays. The influx of fresh water intrusion into the Chesapeake Bay could also be a major problem for the fishery industry if the Susquehanna experiences extreme flooding. Secondary flooding affects for the Delaware River, Schuylkill River, Neshaminy Creek, Perkiomen Creek and Lehigh River should be a major concern as well. New Hope and other towns along the Delaware should be on alert by this weekend if the ideal track comes to fruition. I agree that a short wave combined with a washed out tropical storm in our area would be more disastrous with the heavy rain.

That's a very Floyd-like track but a bit slower.

I distinctly remeber Floyd in Sept 99 being proceeded by flooding rounds of T storms in August.

Fortunately, that basement flooding got me installing a pump and waterproofing just before Floyd arrived.

I'll be excited if we only get 2 inches of rain out of this. After 9 inches in the last 8 days, I can live with that.

Just curious - what is the max it is showing for central pa?

euro brings irene over lanc and abe...heaviest rain in central pa..del reiver west 2 plus inches.

I'm not. Just ordered a gas generator as a backup to my battery backup for the sump pump. Prepping for shock and awe. Hoping for Partly Cloudy and Breezy.

I wouldn't rule anything out yet..."shock and awe" to "partly cloudy and breezy" (and everywhere in btwn) are still all on the table...:maprain:

Wow, good call. I don't have any redundancy built into our sump pump. I will have to remedy that this week...My actions will of course dictate the outcome. The more $$$ I spend on preparation, the further out to sea it will go...:arrowhead:

Here's a good battery backup system.

If you are going to be home to switch over in the event of an outage, you can get a 4000W gas generator for under $400, but you need a dry place outdoors to run it.

Good stuff, thank you for the links...

Nowhere for a generator outdoors just yet, but I am planning to build a shed in the yard next year, so I could provision to store it in there (with the proper ventilation of course). May I ask where you are planning to store yours?

Nowhere either. My hope is that, in the event of an outage, the battery backup will hold things over until the rain is gone. It is rated for 7 hours of continuous running. I'd put the generator up after the storm (really a backup in case we have a long outage, which is always possible in a TS.)

Plan B if the battery does not last is manually emptying the sump using buckets.

If it's worse than that, I guess plan C is re-finishing the basement after it floods.

A battery is only going to last so long too in the event of a power loss. I got a backup system that runs off of the water line in the house and drains through the sewer lines. It requires no power at all and runs off of suction created by the running water in your house. Its expensive but it works well and you never have to worry about losing power and then battery.

this is the big issue, especially the immediate phl metro area. Granted we will have a couple days to relax the rivers and what not so these numbers will drop. But their on thursday and friday tstorms come back into the picture which could raise everything back to where they are now, then we see what happens with irene which could be bad.
