Speaking of construction and technology seems everyone as of late in the media is talking about Joplin, Missouri's new "tornado proof" hospital being built. Here is one of the latest videos I ran across from the Weather Channel. I guess it is possible to build a structure now days to withstand a tornado, even the glass. http://www.youtube.com/watch?feature=player_embedded&v=PMQ_sU2pVfk
One issue I have with OKC metro's warning policy is they sound the sirens for all metro areas if any part of the city is within a tornado warning polygon.
We heard sirens all night in far north OKC (178th/May..we are talking like 20 miles north of the threat).
My fear is that one day a south metro tornado will be warned, and then a few minutes later a new north metro tornado will pop up. The people will assume that the sires are just recycling the warnings from the south metro tornado. Too many sirens in my humble opinion.
Yes I finished your book last week which got me thinking about this during the Friday weather. Really interesting read! I'm working on "Warnings" this week. :-)
Unfortunately I can't think of a good solution. OKC is broken into 8 wards that change every year based on census data. I'm assuming the tornado sirens can't be updated every year to adapt to the updated GIS data.
(Keep in mind I'm just an amateur storm spotter) One idea I had is to develop software that links the GIS coordinates from the metro wards with the tornado sirens positioned in those areas.
So when a tornado polygon is drawn over a specific area on the map, the software would figure out which OKC metro wards are impacted and activate those sirens.
Someone would still pull the switch on the sirens, but the software would help decide which sirens in the metro sound.
Easier said than done I'm sure. And probably expensive! But that is the fun at being an armchair critic. :-)
2am While the risk of tornadoes may continue during the night, this will have to end my coverage. Note the risk of tornadoes farther east later today. 1:35am Wednesday: Tornado watch will likely be issued for the outlined area, including the Kansas City Metro. Make sure you have a way to receive tornado warnings the rest of the night. 11:55p Tuesday: New tornado watch has just been issued for most south central (including Wichita), southeast and east central Kansas. This watch is in effect until 7am Wednesday. This is the overnight tornado threat we've been talking about. I am now providing additional updates on Twitter/X @usweatherexpert . --- original posting (still valid) --- Now until 7a Wednesday The tornado risk has decreased in Oklahoma south of I-40. 7am to Noon Wednesday For Wednesday morning, there is a significant chance of tornadoes in western and, especially, northern Missouri. It is unusual to have tornadoes during the morning....
A major windstorm is forecast for Oklahoma and Texas Sunday. This has the potential to cause widespread power failures. Please prepare now. More information below. 5:35pm: Particularly Dangerous Situation watch due to wind gusts forecast to reach 105 mph and with hail 5" in diameter. Tornadoes also possible. If you live in a mobile home, now is the time to determine your sheltering situation. I urge you to shelter before warnings are issued (spend the evening with friends or family). Power outages are likely. A mobile vehicle from the National Severe Storms Laboratory has already measured a gust of 90 mph! 3:05pm Update: Computer models have consistently increased their forecasts of peak wind gusts pertaining to north central Texas this evening. Wind gusts of 110 mph are possible. If correct, widespread power outages are likely. First Watch of the Day Pertaining to the Derecho In addition to the threat of tornadoes, wind gusts of 80...
It is imperative residents of the central Great Plains use the forecast to prepare for damaging winds and, perhaps, a tornado or two. Tornado Risk The brown area has been moved south into northern Oklahoma and now includes Bartlesville, Ponca City, Enid, and Stillwater, in addition to the cities shown. In Missouri, it includes Joplin and Nevada. Destructive Thunderstorm Winds Here is the color code: Pink and hatched: High risk of destructive winds of 75 mph or stronger. Red and hatched: Enhanced risk of wind gusts of 75 mph or stronger. Yellow: Significant risk of winds 60 mph or stronger. If you live in the red or pink areas, I urge you to prepare for the potential for power outages, some could last a day or more. Bring in lawn furniture or trampolines which could blow about and crash into other objects -- increasing damage. Put your car in the garage or carport.
I'll pass it along to my team. Thanks for writing it.
ReplyDeleteWhat is your opinion on ICF construction and tornado safety?

@Dr. I don't have an opinion on that as I am not a structural engineer. Sorry.
ReplyDelete@Todd: Yes, it is possible to make it tornado resistant although not completely tornado proof.
Great article.

@David: A version of your fear materialized in Joplin in May, 2011. It is described in my book, "When the Sirens Were Silent."
