NOAA weather radio is beeping at us. Flash flood warning. Up to three inches of rain has already fallen.

Mr. Big Food remarks that he will not be cutting today.

I need coffee.

A Little Exercise

In reply to SueK, who commented that she could not fathom 20″ of rain– what’s forecast for NOLA.

20″ is indeed a lot of rain. We could get up to 10″. Here’s something I once had my students do– a very long time ago– when teaching both metric system, and some environmental biology.

Take some paved outdoor space of reasonable dimension– driveway, small parking lot. Measure length & width in feet or yards. Set aside.

1 inch of rain is a volume of water– 1 cubic inch.

1 inch = 2.54 cm. 2.54 * 2.54 * 2.54 = 16.39 cubic cm. Round down (so as not to over inflate the eventual stat) and once inch of rain is 16.3 cubic centimeters of rain.

By definition, 1 cubic centimeter of water = 1 ml (and has a mass of 1 gram but that’s irrelevant here) [and I can’t remember but there’s a pressure component to this too]

1″ rain = 16.3ml.

Convert your measurement of the driveway to cm. Let’s say 10′ x 20′ … 304.8cm & 609.6cm, respectively.

Now, drop an inch of water on that surface.

304.8 * 609.6 * 16.3 = 3,028,639.1 cubic centimeters or ml of water.

How many liters is 3 MILLION milliliters? 3028.6391 call it 3028.

Divide by 2 b/c everyone knows how much is in a 2-liter bottle.

One inch of rain falling on a paved surface measuring 10′ x 20′ is more than 1500 2-liter bottles of water. It can’t go down, so it runs off.

Burn ban head scratcher

I swear to God, those folks in Louisiana make us Mississippians look down right intelligent some days. Let’s go look and see if the iPad has a therefore sign. It does not. But you know what I’m talking about. That little triangle of dots that indicates, e.g.,

Hurricane therefore burn ban

Run on sentence.

I am confused about the context. Must be Drudge related.

UPDATE. This is such typical hyper-BS. It’s New Orleans. It has more water than land, and a significant portion of the land is below sea level. And it rained! Oh boy!

Why are they out walking around hamming it up for the camera? Good lord. Just think– we have probably four days of this to look forward to.
