Do certain weather conditions scare you?

Scared of the weather?  Maybe you have a weather phobia!
Scared of the weather? Maybe you have a weather phobia!

As recently reported in the Washington Times, if you find yourself suffering anxiety or fear from hurricanes, tornadoes or other weather phenomena, you are not alone. 

In 2006 researches at the University of Iowa surveyed 139 adults.  Of those more than half felt panicked by big storms and only a quarter felt no fears at all about the weather.  During severe weather season it is not unusual to be quite concerned and touched by a bit of fear when you live in an area that is in danger such as along the Gulf Coast during hurricane season or closer to home here in Colorado when a tornado warning is issued.  Most anyone would experience anxiety over an approaching storm that threatens to damage life and property. 

Certainly one can help limit stress about severe weather by being knowledgeable about the type of weather and by extension, remaining calm.  Oftentimes fear is caused by the unknown and if you are more aware and learned on the topic, you are more able to deal with the stress.  Further, a bit of fear can help you survive a situation simply because you are more in tune and aware of what is going on. 

A true phobia though is by definition, “an uncontrollable, irrational, and persistent fear of a specific object, situation, or activity.”  Professional help of course is most likely the best way to deal with phobias.  We have all heard about extremely odd phobia such as the fear of drinking (Dipsophobia) or the fear of lice (Phthiriophobia).  As it turns out there is an entire range of phobias specifically related to weather as well. Davis Weather Instruments recently compiled a list of some of the weather-related phobias including:

  • Ancraophobia or Anemophobia – Fear of wind
  • Astraphobia, Astrapophobia, Ceraunophobia, Keraunophobia – Fear of thunder and lightning
  • Auroraphobia- Fear of Northern lights
  • Chionophobia- Fear of snow
  • Frigophobia, Cheimaphobia, Cheimatophobia, Psychrophobia – Fear of cold or cold things
  • Homichlophobia or Nebulaphobia – Fear of fog
  • Lilapsophobia – Fear of tornadoes and hurricanes
  • Ombrophobia or Pluviophobia – Fear of rain or of being rained on
  • Pagophobia- Fear of ice or frost
  • Phengophobia- Fear of daylight or sunshine
  • Tonitrophobia- Fear of thunder

Discovery Channel’s Storm Chasers to premiere October 19th

StormChasers
Discovery Channel's Storm Chasers

Just announced!  The Discovery Channel’s Storm Chasers second season will premiere on Sunday, October 19th.  For those that haven’t seen this show before, it is absolutely incredible as you follow a group of chasers trying to – literally – drive into a tornado.  As you know, the 2008 tornado season was one for the record books and the Storm Chasers team was right in the thick of it.  I will be watching with great interest as they spent a lot of time in north central Kansas right where my family is from.

Three tornadoes and multiple funnel clouds were reported in Elbert and Douglas counties Sunday evening.  At 5:31pm the Centennial Airport tower reported a tornado on the ground five miles southwest of Parker.  This was followed by a second tornado reported at 5:47pm six miles northeast of Parker.  Lastly, a third twister was spotted three miles west of Castle Rock reported by trained spotters at 6:03pm. 

News video showed the tornadoes weaving through relatively unpopulated areas interspersed wtih some houses.  Authorities currently report no major damage. 

Tornado warnings were issued but have now expired.  As always, please be aware of the weather situation around you and when a danger presents itself, take appropriate action. 

Update, 8/25/08, 7:50am – Reports are varying on the actual number of tornadoes that touched down.  We have seen reports as low as two twisters to as many as a dozen.  Chances are the actual number is toward the lower end of that range as oftentimes the same tornado is reported by multiple spotters with different descriptions of their locations.  The National Weather Service investigates these and at some point in the future will determine the true number of tornadoes.

Here is some video shot by a Parker resident:

Rare mountain tornado strikes Park County Saturday

In a truly unusual weather occurence, a tornado struck near Eleven Mile Reservoir in Park County Saturday afternoon.  Certainly we are all used to hearing about twisters along the Front Range and on the plains but mountain tornadoes are quite rare – the rugged terrain usually disrupts the weather patterns necessary to product tornadoes.  Authorities estimate five vehicles were damaged including a motorhome and pickup truck camper that were overturned, a trailer was destroyed.  Beyond cuts and scrapes, thankfully no one was injured. 

Colorado is ranked ninth in the country with an average of 40 tornadoes a year.  It is interesting to note that every state in the union – including Alaska and Hawaii – have had tornadoes. 

Doing some research at the TornadoProject.com yields an interesting fact as well.  This was Park County’s first tornado ever.  That leaves 12 of Colorado’s 64 counties that have never had a tornado including:

Clear Creek
Dolores
Garfield
Gilpin
Gunnison
Hinsdale
Lake
Montrose
Ouray
San Juan
San Miguel
Summit

It does serve as a reminder that while the unofficial severe weather season is behind us, Colorado’s weather is anything but boring and everyone should be aware of all the types of weather hazards that are possible.

Forecasters increase hurricane chances

NOAA says there is a greater chance for hurricanes in the coming months.
NOAA says there is a greater chance for hurricanes in the coming months.

In their August update to hurricane season forecasts, experts at the National Oceanic and Atmospheric Administration (NOAA) have changed their predictions for the season and now expect a greater chance of hurricanes this season.  They are now predicting an “above normal” season with 14 to 18 named storms – up from the 12 to 16 they predicted in May.

The forecasters now believe there is an 85 percent chance that this above normal trend will take place (up from 65 percent in May). 

“Leading indicators for an above-normal season during 2008 include the continuing multi-decadal signal – atmospheric and oceanic conditions that have spawned increased hurricane activity since 1995 – and the lingering effects of La Niña,” said Gerry Bell, Ph.D. of NOAA’s Climate Prediction Center. “Some of these conditions include reduced wind shear, weaker trade winds, an active West African monsoon system, the winds coming off of Africa and warmer-than-average water in the Atlantic Ocean.”

Thus far in 2008 there have been five named storms and the most active hurricane period – August to October – is just now beginning.  Will this prediction hold true?  Unfortunateley forecasters have struggled in recent years with their predictions.  Last year NOAA predicted 10 hurricanes and only six formed. The year prior, 2006, nine hurricanes were forecasted by NOAA but only five formed.  In 2005, the year Hurricane Katrina devastated New Orleans in the worst U.S. natural disaster, the forecasts underestimated storm activity.

Thunderstorm brings funnel clouds, severe rain

An exciting evening in Thornton as far as the weather goes.  Just before 6:00pm Wednesday a slow-moving severe thunderstorm over north Thornton brought everything from funnel clouds to lightning to torrential rain. 

The Thornton radar image when the storm was at its height. The storm dumped over 2" of rain in 1 hour.

Rain began falling in the area of 120th and Colorado Blvd at 6:00pm and over the next 70 minutes dumped 2.36″ of precipitation.  Lightning and thunder were predominant for the entire time as well.  At 6:40 the National Weather Service issued a Tornado Warning when several funnel clouds were spotted between south Thornton and Dacono.  These slow moving storms presented a clear and present danger but appear to have passed relatively uneventful.  Minor street flooding has been reported in some parts of Thornton but otherwise little damage.

As of this writing, a Flood Advsiory and Flash Flood Watch remains in effect for much of the Denver metro area.  Radar does indicate the storm is deteriorating and things should beging to settle down now. 

As always, please stay tuned to ThorntonWeather.com for the latest.  Be sure to monitor our Warnings and Advsiories page for realtime updates on current watches and warnings.

Area King Soopers Offers Discounted Weather Radio

All Hazards NOAA Weather RadioWe recently wrote about systems which provide severe weather alerts to the general public.  In writing that, we extolled the virtues of having a “weather radio” – a specialty radio that allows you to listen to and monitor the NOAA Weather Radio All Hazards (NWR) system.

Midland WR-100 Weather RadioWe just read on KMGH channel 7’s website that all Front Range area King Soopers are offering a very good deal on a Midland WR-100 radio.  These are similar to the WR-300 model we discussed previously – just with fewer bells and whistles.  The WR-100 retails for $49.99 but through September at area King Soopers stores you can buy one for $29.99. 

You can find more information on channel 7’s website including a list of area King Soopers stores and even a video that walks you through how to set the radio up.  This is a great deal and we would encourage everyone to take advantage of it. 

Windsor Tornado Officially Rated as EF3

The National Weather Service has completed their tornado assessment of the Windsor tornado and determined the twister was rated an EF3 on the Enhanced Fujita scale.  See below for details and here for a map of the path the twister took

PUBLIC INFORMATION STATEMENT…UPDATED…
NATIONAL WEATHER SERVICE DENVER CO
430 PM MDT FRI JUN 6 2008

..WELD COUNTY TORNADO OF MAY 22 2008 RATED AN EF3 TORNADO…

On Thursday May 22 2008 a wide and powerful tornado swept north northwestward for 34 miles from northeast of platteville in Weld County at 1126 AM MDT to 7 miles east northeast of Fort Collins in Larimer County at 1216pm MDT.   The National Weather Service tornado damage assessments conducted on Friday May 23rd and Saturday May 24th documented large areas of damage.  On the enhanced Fujita scale there were pockets of EF3 damage especially near the Missile Silo Park Campground west of Greeley and to homes and businesses in eastern Windsor.  Wind estimates in the heavily damaged areas were as high as 130 to 150 mph. 

The tornado was as wide as one mile at times along its path.  There was one fatality and 15 to 20 injuries.   Damage estimates are not finalized, but preliminary numbers from FEMA are 850 homes damage, with nearly 300 homes signficantly damged or destroyed.  Privately insured damages total 174 million dollars…and the Poudre Valley Rural Electric Association reported one million dollars of damage to electric transmission facilities.  

One question frequently asked is how unusual was this event.  Certainly it was not unusual in time of year (May and June are the peak tornado months in Colorado).  It was not unusual in location (more tornadoes are reported in Weld County than any other county).  It was slightly earlier in the day than normal, as we usually see tornadoes in the mid afternoon to early evening.  The track was longer than most, the tornado was moving fastern than most,  and a track moving north northwest is very unsusual.  Since 1950 there have been a total of 20 tornadoes of f3 and higher within Colorado.  This was the second f3 tornado reported in weld county since 1950.   On May 15, 1952 an F3 tornado injured 5 people within the county. 

For reference…the Enhanced Fujita Scale classifies tornadoes into the following categories:

EF0…wind speeds 65 to 85 MPH.

EF1…wind speeds 86 to 110 mph.  

EF2…wind speeds 111 to 135 mph.

EF3…wind speeds 136 to 165 mph. 

EF4…wind speeds 166 to 200 mph. 

EF5…wind speeds greater than 200 mph.

Tornado Watch Issued for Metro Area – Northeast Colorado

Tornado Watch issued for Denver.The National Weather Service has issued a Tornado Watch for much of northeastern Colorado including the Denver Metro area.  Counties under the watch include Adams, Arapahoe, Denver, Douglas, Elbert, Kit Carson, Lincoln Logan, Morgan, Phillips, Sedgwick, Washington, Weld and Yuma.  This watch is in effect until 8:00pm tonight. 

Tornado Watches are issued when weather conditions are favorable for the development of severe thunderstorms that are capable of producing tornadoes. A tornado watch therefore implies that it is also a severe thunderstorm watch.

As we all saw two weeks ago in Weld County, conditions can quickly deteriorate and the weather can present a very real danger to life and property.  Now would be a good time to run through tornado emergency procedures in your mind. 

Please remember, should the tornado threat increase:  Get in, get down and cover up!  A well built structure with a basement is ideal shelter but if that is not available, an interior bathroom or closet is next best.  Modular and mobile homes are NEVER a good option nor are vehicles.  If you are in a vehicle and a tornado is near, abandon it immediately and seek shelter in a low lying area such as a ditch. 

For these and other tornado safety tips, please see our Severe Weather 101 – Tornadoes

How do you know when something bad is coming?

Emergency Alert Sirens - Not in Thornton!I was recently asked how prevelant tornado sirens are in the metro area and thought that would be a good discussion to have.  Tornado and alert sirens do exist in some municipalities in the Denver metro area but not all. Boulder has a system (primarily due to flood dangers) as does the city of Denver itself. Many of the other suburbs however do not.  Unfortunately, Thornton does not which to me is somewhat odd as in 1981 Thornton was struck by one of the few tornadoes to have hit the metro area so you would think that would have caused them to consider building a system back then.  If you are reading this and live in another municipality, give them a call to find out if one is available in your area.

The sirens definitely do provide a service to the community.  However, USA Today just had an article discussing these types of systems and pointing out that they were expensive to maintain and of limited effectiveness.  Some municipalities have depended on reverse 911 systems to alert residents but it is my opinion that these to are limited because they rely on someone being home to answer the phone.  What if you are in an area park and a tornado is coming? People today are very mobile and a solution that takes that into account and can warn people wherever they are would be ideal.

The city of Dacono recently deployed a system that I think Thornton should give some thought to.  You can read more about it here but in essence residents can sign up to receive alerts on their home phone, cellular phone and email.  Within a matter of seconds, thousands of subscribers can be notified of everything from weather events to disaster updates to AMBER alerts for much less than the cost of a siren system.  ThorntonWeather.com is going to be discussing the idea of this type of system with Thornton City Council members in coming weeks so be sure to check back to see what we learn.

NOAA All Hazards Weathe RadioIn the meantime, probably the best way to ensure you are warned about approaching dangers is to purchase what is commonly known as a “weather radio.” These radios are relatively inexpensive (around $40.00) and allow you to listen to and monitor the NOAA Weather Radio All Hazards (NWR) system. NWR broadcasts official Weather Service warnings, watches, and forecasts as well as other hazard information like earthquakes, avalanches, chemical spills, and even AMBER alerts. These broadcasts continually run 24 hours a day, 7 days a week and provide a great way to stay up to date with developing weather conditions.  One of these radios is actually what broadcasts our weather radio system here on ThorntonWeather.com.

Some of the nicer units even use what is called SAME – Specific Alert Message Encoding – which I would highly recommend. In essence you program in a code for the area in which you live and the radio will automatically turn on and sound an alert when something of note is in your area. These weather radios are very popular in rural areas in Tornado Alley but as we saw last week in Windsor, they definitely can be useful here along the Front Range as well. More information about the system can be found on the National Weather Service’s website and you can find these at many electronics retailers, particularly those on the Internet like Amazon or NewEgg.

Midland WR-300 Weather RadioWhich weather radio do we use?  We are hesitant to recommend specific products but our radio of choice at the current time is the Midland WR-300.  This radio has the important SAME coding feature, a text display to show you what sort of alert is occurring, battery backup and more.  We have been pleased with the two we have.  NewEgg carries this model for $47.99.
