Five tornadoes tore through parts of southeast Colorado yesterday, leaving several injured and causing considerable damage to farming communities. 

According to the National Weather Service two tornadoes hit Prowers County, two tore through Kiowa County,  and one went through parts of Bent County in the early morning hours of April 27th.

According to the Denver office of the National Weather Service, overnight twisters in Colorado are rare.  The last time an overnight tornado hit the state was April 30th, 1942.  Ironically it hit the same two counties of Bent and Kiowa, the same areas hit this year.

There are numerous shows on TV, like on Discover Channel or the Weather Channel, that glorify storm chasing.  They make it look so fun and cool to be out racing down the highway trying to get right up next to a monster tornado.   Despite being pelted with hail stones, flying branches, torrential rain, and lighting, the vehicles press on with a sense of immortality.  As we all know, TV shows don’t always portray the whole story.  Certainly when it comes to tornado safety, these chasers often push the limits way beyond comprehension.

 Be that as it may, there is an ongoing debate and uncertainty about what is the best course of action if you are in a vehicle with an approaching tornado to deal with.  The conventional wisdom when I was growing up and even during the first decade of my weather forecasting career was that one should always leave the vehicle and go lie flat in a ditch or ravine and cover your head.  Over the past 15 years there have been some high profile cases where people were actually severely injured or killed by leaving their vehicles and going under overpasses or just going out in the open.  Now there is more of a recommendation to use your best judgement based on a number of factors whether to leave your car or not.  Below is a statement from Roger Edwards of the Storm Prediction Center that goes into more depth on this subject.

In a car or truck: Vehicles are extremely risky in a tornado. There is no safe option when caught in a tornado in a car, just slightly less-dangerous ones. If the tornado is visible, far away, and the traffic is light, you may be able to drive out of its path by moving at right angles to the tornado. Seek shelter in a sturdy building, or underground  if possible. If you are caught by extreme winds or flying debris, park the car as quickly and safely as possible — out of the traffic lanes. Stay in the car with the seat belt on. Put your head down below the windows; cover your head with your hands and a blanket, coat, or other cushion if possible. If you can safely get noticeably lower than the level of the roadway,leave your car and lie in that area, covering your head with your hands. Avoid seeking shelter under bridges, which can create deadly traffic hazards while offering little protection against flying debris.

We’ve all seen the horrific images of vehicles twisted around tree trunks 20 feet in the air, or turned upside down and crushed.  Or how about the photos of beams or lumber jabbed straight through a car window or door.  What a horrible thing if someone was in that vehicle in such cases.  I wish I had a hard and fast rule for you when it comes to automobiles and tornadoes.  I hope you never have to make such a tough decision but if you do, try not to panic.  Take care.

For the first time in four years, the Northern Plains will not experience major to record spring snowmelt flooding.  Of course the reason being is that there was very little snowpack in that part of the country throughout the winter.  Most of the major winter storms either missed that area, or it was warm enough that the snow melted off and on over the winter months.  The record warmth in March took care of the rest of any remaining snow pack in the Upper Midwest as well.  This is certainly great news for residents in Fargo and Grand Forks along the Red River as well as folks along the Mississippi River.

There is also a lower than normal risk of spring flooding in the southwest quadrant of the county as well as an area from Florida to parts of Virginia.  Only a few spots in Louisiana, Mississippi, Kentucky, and southern Indiana, and southeast Illinois have an above normal chance of spring floods according to NOAA.

The bad side of lower than normal spring flood risk in the Northern Plains and Midwest is the fact that this usually means the ground will dry out sooner than normal.  Thus there is a somewhat increased chance of growing season drought, unless frequent rains start to show up.

The Intergovernmental Panel on Climate Change(IPCC) released its Special Report on Managing the Risks of Extreme Events and Disasters to Advance Climate Change Adaptation (SREX) on 28 March.  You can read the the full press release from the following link.  http://ipcc.ch/news_and_events/docs/srex/SREX_launch_media_advisory.pdf

The report was authored by 220 scientists from 62 counties around the world.  It was based off of hundreds of studies from across the globe that have been peer-reviewed at least 2 to 3 times.  Some of the major points in the press release regarding climate change over the coming decades include.

• Heat waves will likely increase in frequency, duration, and intensity.
• Sea levels will very likely continue rising, causing increased coastal flooding.
• Heavy precipitation events will likely to increase in frequency especially in higher latitudes and tropical regions during the summer and in northern mid latitudes during the winter.
• It is somewhat probable that droughts will increase in duration and intensity especially in central and southern Europe, the Mediterranean Area, North America, Central America, Mexico, northeast Brazil, and Southern Africa.
• It is extremely likely that the frequency of daily record high temperatures will increase and daily record low temperatures will decrease across the globe.
• It is likely that economic losses from climate-related disasters will increase.  (Part of this is due to greater population with time living in risky areas).

You can read the full 600 page IPCC report here.  Good luck!  http://ipcc.ch/news_and_events/docs/srex/SREX_launch_media_advisory.pdf

A boat that was part of the five million tons of “stuff” thrown into the Pacific Ocean during the massive Japanese earthquake and tsunami has been spotted off the Canadian Coast. 

The Associated Press is reporting that the 65-meter long boat is moving toward land, 160 miles off the coastline of British Columbia. 

To put that in perspective, if you were driving down Interstate 39, that’s about 20 miles farther than the distance between Wausau and Madison!

The horrific earthquake and tsunami struck Japan just over one year ago on March 11, 2011.  More than 15,000 people died and it brought about one of the biggest nuclear power plant scares in years.    

According to The Toronto Star, there is no environmental concerns over the abandoned ship, but mariners in the Pacific Ocean need to take warning because “the vessel poses a potential navigational hazard.”

The rumors have been flying for the past few years that December 2012 will be the end of the world.  A lot of the hysteria has been fueled by the so called Mayan calendar reaching the end of its cycle at that point.  Throw  in the wacky weather and climate of the past few years, unprecedented  March heat, earthquakes in Clintonville, WI, terrible world economies, and a movie dealing with Earth’s demise, “2012″, and you have all you need to stir up a frenzy.

Well some NASA folks have set out to debunk all the end of the world hysteria.  They have put together a nice article that basically says there is no science, no evidence, and no facts to support the claim that 2012 is the end.  They dive into the following items and explain why we should not be overly concerned about them for this year.

• Planetary alignment
• Magnetic pole shifts
• Planets or brown dwarfs approaching Earth
• Meteors, comets, and asteroids
• Giant solar storms
• Super novas
• Super volcanoes
• Mayan calendar

Well if you are worried that our days are numbered, please check out this NASA link.  It should give you a bit of reassurance if nothing else.   http://www.nasa.gov/topics/earth/features/2012.html

Did you know that March 12th – 16th is Flood Safety Awareness Week in the U.S.?  Flooding is one of the top weather killers every year in the country.  Of course it also produces huge amount of property damage.  I’ve seen some streams and small rivers out of their banks the past few days with the rapid snow melt and light to  moderate amounts of rain we’ve had.  Most of the flooding has been lowland and agricultural in nature so far.

 We are really lucky we didn’t have a 2 to 3″ rain storm or we could have been in a lot of trouble when it comes to flooding.  Even though the snow melt flood risk is diminishing now because we never really built up that huge snow base like other winters we still need to be on guard.  This is especially true because the developing pattern is one that could feature shower and storm chances for about a week in a row starting this weekend and going through next week.  Seeing that it will be unseasonably warm and humid, some of the showers certainly could produce heavy rain.  Therefore we can’t rule some flooding problems as the month goes on.

This is certainly a great time to refresh your memory on what flood terminology means, see what new technologies are helping us forecast floods better than ever, and consider buying flood insurance.  These topics and many more are covered in a great brochure put together by the National Weather Service.  It has many fascinating photos of flooding and its power within it as well.  Be sure to check it out at this link.   http://www.nws.noaa.gov/om/brochures/Floodsbrochure_9_04_low.pdf

A fairly large chunk of the country as of the February 7th was on the dry side.  NOAA and the USDA reports abnormally dry conditions across the western half of Upper Michigan into the northwest half of Wisconsin.  Minnesota is in rougher shape with much of the state listed as in a moderate to severe drought.  That extends into the far eastern portions of the Dakotas.  Moderate to severe drought is also plaguing the western U.S. from the Great Basin down into the Desert Southwest.  They have not had many snowstorms this winter out there either. 

 Some of the same areas that were at record dry levels last growing season from southern Kansas to much of Texas are still in a severe to extreme drought.  It is also very dry around Florida, Georgia, and right up into the Carolinas.

According to the seasonal drought outlook into the summer, the drought is expected to overall persist in many sections that currently are so dry.  Let’s hope it doesn’t expand across Wisconsin.

Every year we provide tips for surviving severe weather events here in Wisconsin. There is a Tornado and Severe Thunderstorm Awareness Week, A Flood Safety Week, Lightning Safety, Safe Boating Week, and Winter Weather Awareness Week, just to name a few. While researching safety tips for an upcoming presentation, I thought I would look at some other types of disasters that do not normally happen in Northcentral Wisconsin, just for my own knowledge, because I never know what might happen in places where I might travel. 

I lived in California for almost a year but I never did feel or experience an earthquake. It must have been one of the quietest earthquake years in California’s history. I didn’t even feel a minor tremor. It is probably a good thing, because I didn’t know how to protect myself in the event of a big quake. I am not going to go through all the different safety and preparedness tips here in the blog, just a couple interesting things I learned. For more in depth information here are a couple of websites I found useful:

Geology.com and National Geographic

One of the more interesting tips was that if you are sleeping when an earthquake happens, you should stay in bed and cover your head with a pillow. Also, if you are cooking, it is reccommended you turn off the stove before seeking safety in your home. I suppose the danger of an electrical or gas fire due to the stove being on is greater than threat posed by delaying your move to get under something sturdy and away from the walls and windows.

When looking at Hurricane safety and preparedness, it seemed fairly simple. Most of the action occurs before a storm arrives. The main safety advice is to just evacuate – have a family disaster plan in place and then be ready to evacuate. Be sure to take your pets as well. Once an area is quarantined by the authorities, they will not let you in no matter what. I have heard second hand of horror stories where people were literally just a few yards from their starving pets but they were not allowed to cross the barricade/check point in order to save them. One piece of advice that I did not find on official hurricane safety sites was to keep an axe in your attic. This is advice I have heard from other people and it is mentioned here. The idea here is that if there is major flooding during or after a hurricane and you are trapped in your house, you can use the axe to chop a hole in your roof so you can get out.

Do any of you have any hurricane or earthquake stories to share? What about any other odd natural disasters that don’t normally occur in Northcentral Wisconsin?

We certainly have not had to deal with many Winter “disasters” this year. The Winter has been pretty tame, but it was not predicted to be that way by some. If you remember back to the Fall, the Farmer’s Almanac and Accuwx were at least two sources that were predicting very harsh Winter conditions across the Midwest, including Wisconsin. I think those forecasts were based mainly on the fact that La Nina was occurring in the Pacific. Last Winter there was a La Nina in the Pacific and it WAS a bad Winter. This year was almost the opposite.

You will recall that even I was predicting a little below normal temps and a little above normal snowfall – mainly due to La Nina. I didn’t go overboard because this Winter’s La Nina was not as strong as last Winter and because I know that La Nina historically has not had as strong an influence on our Winter weather as El Nino. It is true that the last 3 La Nina’s brought colder and snowier winter conditions to Wisconsin, but if you go farther back in history, the correlation is not as clear.

Computer Forecasts for ENSO Trend

So what is La Nina up to now? A moderate La Nina is still occurring but it has shown signs of slight weakening in the past month. Here is the latest monthly diagnostic discussion. The computer models are forecasting a continued weakening over the next couple of months, enough so that it is gone (temps in the ocean would be neutral) around May. I just hope that all of our Winter weather has not been saved-up only to be unleashed upon us in March and April. I wouldn’t mind see some above normal precipitation this Spring (I hate droughts), just as long as it comes as rain and not snow & cold.

Have a fine Friday! Meteorologist Justin Loew.

Satellites from the National Oceanic and Atmospheric Administration helped rescue 207 people in 2011 across the United States and surrounding waters.  The communications they provide are the key.  Of the 207 rescues, 122 were on water, 14 involved aviation, and 71 were land situations.  Of the land events, Alaska had the most with 39 followed by Florida with 11 and California with 8.

The NOAA satellites are integrated into an international search and rescue satellite aided tracking system called COSPAS-SARSAT.  Since 1982 this system has supported 30,000 rescues worldwide.  You can read much more about it at the NOAA link here.  http://www.noaanews.noaa.gov/stories2012/20120123_sarsatrescues.html
