so do you subscribe to the post so you can read it?

Doesn't this happen to Ellicott City somewhat regularly? I feel like this is not the first time I've heard of this

In two hours, nearly six inches of rain had fallen, an event so extraordinary that the National Weather Service said it should, statistically, occur there just once every 1,000 years.

So, no.

As a hydrologist, I cringe every time someone on the news uses "100-year storm" or "1000-year storm".

The 100-year storm is an "exceedance probability", meaning there is a 1 percent chance of a storm of that magnitude occurring in a given year.

Old Elliott City was regrettably built at the confluence of about 5 streams.  Someone has cherry picked a piece of data somewhere in that watershed where 6 inches of rain fell.  A 1000-year event, while technically true, isn't the whole picture.

Yes it floods frequently there.  Development in Howard County most likely makes runoff more intense then it once was.  Climate change is also throwing our statistics out of whack.

^WOWZA! Someone who actually knows what they're talking about!!!!!!!!!

So more like an 800-year storm, then?

Guys I have it on good authority that Hydrogen makes up 2/3rds of all water. It logically follows that IamHydrogen knows what the fuck he's talking about when it comes to rain.

He also knows, phish.  What a blast from the past, that guy is. And to come out of nowhere like that. In a thread about the weather.

Gurl.

Seconded. I love that he has 20 posts in a decade and just showed up to school everyone on rain.
