Working on Hazard Mitigation Plan

[Mule]

We are working on the Hazard Mitigation Plan require by the State of Texas. There are several emoloyees working on this document. In reviewing the documents a ran across something that made me go WHAT!!! Well duuuhhh!!!

It in the section of Risk Assessement Matrix there's a section on thunderstorms. The definition of a thunderstorm is what I found quite entertaining. see if you agree!

Severe Thunderstorm and High WindsA thunderstorm is a rain shower during which you hear thunder. Since thunder comes from lightning, all thunderstorms have lightning. A thunderstorm is classified as “severe” when it contains one or more of the following: hail three-quarter inch or greater, winds gusting in excess of 50 knots (57.5 mph), or a tornado. High winds are classified as those exceeding 50-60 mph from any source. High winds are most often associated with severe thunderstorms.

Duuuuh!

It's possible there might be folks out there that have not, or don't experience this kind of weather, either because of where they are from, or they just may not be familiair with the State definition. So the definition is in there so everybody working under the plan is working from the "same playing field" ? Sounds good to me.

It does make sense..I just thought it was a little "well duh" of course you thunder if it's a thunder storm.

And it is an intern writting up the document. So I guess they are trying to use a little common sense. It was just a little too much common sense in my opinion.

Common sense is not common, nor it is a universally provided attribute.



Breathe deeply now Mule... "In with good air and out with the bad air,

in with the good air and out with bad air, ...in with the good air and

out with the bad air." :lol:

So if you are deaf and can't hear thunder it is not a thunder storm?

In the U.S., the National Weather Service defines a severe thunderstorm as having large hail being at least 1 inch (2.5 cm), high winds as being 58 miles per hour (93 km/h) or greater, producing tornadoes (though this would result in a tornado warning), or any combination of the three. Prior to January 2010, the size in which hail in a severe thunderstorm would be considered severe was ¾ of an inch; public complacency due to overly frequent issuances of severe thunderstorm warnings and recent studies stating that hail does not produce damage until it reaches one inch in diameter caused the upgrade.[4]

Better be consistant with the NWS

I like mine dry and not shaken:::

Dry lightning is a term in Canada and the United States for lightning that occurs with no precipitation at the surface. This type of lightning is the most common natural cause of wildfires.[40] Pyrocumulus clouds produce lightning for the same reason that it is produced by cumulonimbus clouds. When the higher levels of the atmosphere are cooler, and the surface is warmed to extreme temperatures due to a wildfire, volcano, etc., convection will occur, and the convection produces lightning. Therefore, fire can beget dry lightning through the development of more dry thunderstorms which cause more fires (see positive feedback).

Good information. It's amazing how much one can learn just reading these threads.
