Draco casts claudit librocella!

Carnegie-Stout Public Library will be closing at 4 p.m. today (Thursday, December 20th) due to the ongoing blizzard conditions. We hope that you are all bundled up safe and warm at home!

As you snuggle up with your cocoa, or recover from shoveling the front walk, we've put together a few snow related links to keep you entertained and informed.

First up, Brian in our IT Department captured this time lapse video of the snow falling on Locust St as seen through the windows on the second floor.



If you're wondering about the title of this blog post, the Weather Channel has decided to give names to winter storms this year (just like hurricanes!), and the blizzard that has brought the tri-states to a halt shares a name with a certain Harry Potter character.

Of more practical use, the government has tips for weathering a blizzard safely (http://www.ready.gov/winter-weather). You can check out the latest snowfall totals from the National Weather Service (http://www.nws.noaa.gov/climate/index.php?wfo=dvn), or play around with interactive snow maps (http://www.nohrsc.noaa.gov/).

And never fear Dubuquers! Even though the library is closing early, our OverDrive collection is available 24/7 (barring blackouts)!

Record-breaking rainfall

It may be hard to believe, but last year at this time the tri-state area was dealing with aftermath of record-breaking rainfall.

On the evening of July 27th, a frontal boundary stalled along the Highway 20 corridor, spawning a series of thunderstorms that inundated the tri-states with record rainfall. Here at the library, we watched the streets outside the library flood briefly and momentarily lost power. Lightening struck and damaged the Bishop's Block Building downtown, but the library escaped with little damage, especially compared to many others in Dubuque, East Dubuque and the surrounding area.

While we're no strangers to flash floods and extreme weather here, the July 27-28 event broke six rainfall records for Dubuque, including the most rainfall ever recorded in a 24-hour period (10.62 inches; previous record of 8.96 in 2002), most rainfall recorded in July (16.01 inches; previous record of 12.68 in 2010) and most rainfall recorded in a single month (16.01 inches, previous record of 15.46 inches in 1965). It also caused the Mississippi River to rise four feet in 12 hours, caused an estimated $2 million in damage, left many homeless and resulted in one fatality.
